Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

THANKS FOR WATCHING!!
#EndOfTheUniverse #ConstantAcceleration #CoolWorlds #InterstellarTravel
Imagine if Aliens visited us but it turns out they are just ancient earthlings who just returned from a grand space voyage and to them it's only been 60 years.
We’d probably kill them 😑 We’re so primitive it honestly angers me
They probably feel very dissapointed, and get back in the ship, and make another 60 year trip.
I was thinking about that
What??? You realise when they left we would obviously calculate when they left and would await their arival... and you know they Don't go back in time right?
@@zh9664 did you watch the full video...!
I really enjoyed this teaching. At 74 years old I can say I will enjoy every day I have left in this life. Thank you.
Reading this made me realize at 24 that I need to enjoy every day as well. I spend too much time being stressed out about this or that, and I just want to relax. Enjoy my time here and move on. Good luck and happy life to you
@@mayn90s19 me too man.
Here here. Nice to see your enthusiasm, it really inspires me.
You are doing things correctly fellow human.
I'm 40, and I am just realizing what this man said compared to my twisted life. We need elder people like you to guide us into the labyrinth pf our existence. Your words are our path. Thanks.
This dude is the complete package. Looks like a superstar, speaks like a philosopher, narrates like a poet n possesses knowledge like well, a physicist. One of the best videos you can ever see.
Part of me wishes that Prof. Kipping would be gobbled up to take up the mantle of DegrasseTyson. But then I remember that would likely mean he would have to sacrifice his valuable work and research in some way. I truly am thankful for finding this channel, as you say he is indeed the complete package. A voice that is easy to listen to, highly eloquent and is able to convey complex scientific information in a manner that my 10 year old niece can understand. Though the Prof owes me a lot of money, after finding his channel my love of space was reignited and magnified; so much so that I now spend most weekends (weather permitting) with my newly acquired Astro-photography setup. Lockdown and Kipping are to blame.
They both contribute in their own way. Very different personalities.
And has a British accent!
His existence proves that the world isn't fair. He has all stats maxed.
And good thing he is a youtuber too. Otherwise I wouldn't have chance to watch him.
One of the true masterpieces in the whole youtube platform. Watched this like 30 times....
So true
Same, its like meditation
I just saw it for the first time and I have a feeling I will revisit it many times as well. As well as other Cool Worlds videos. Actually...I don't have words to describe what this makes me feel....
30 is insufficient. Do better!
David, you're a poet. I have never seen a physicist describe the universe so eloquently and poetically as you do. Thank you for these videos. Keep them coming.

@Ali Avci I literally just watched it twice in a row. Beautiful
What a beautiful story....
It’s his accent. Accents like his always make subjects like these more interesting
He's pretty hot too. Just sayin'.
I’m 84 years old and watching this video put a lump in my throat. Beautiful done and very kind of scary to think we will never really know what is out there.
I would suggest you watch "journey to the end of time" by a channel called melodysheep. The best video on youtube in my opinion 👍enjoy🖖
Mr sexy voice can do that at times !

@@jasonhollister7497 Dude stop smoking pot.
Hope your doing well !!
This is actually one of the best videos explaining space and time, that narrator is a pro, I was kinda getting a scared and depressed feeling as the video plays to the end, then finally at the end he makes you feel happy by reassuring you to enjoy the Universe as is. What a story.
We all expect an end to this universe at some point. What I think about, however, is can we outlast our universe? When the universe ends, does that mean our story has to end too as humanity and the legacy with it? Some may argue there is no way possible. I would argue, you have quite the amount of time to figure such a problem out - trillions upon trillions of years. Well, 5 billion or so to get away from the Sun first before it engulfs our Earth but if we manage surviving that, our odds of survival beyond are hopefully pretty good at that point. I like to believe, somehow, someway, we can outlast this universe and live to the next universe to tell our tale. I understand the sheer amount of time it would take to even reach that point. But there could be alternatives. It might be that we can simply travel to another universe rather than wait for a new rebirth that may or may not ever happen. If you subscribe the multiverse theory, there's even variations of how multiverse works, but depending how you believe the multiverses work, I would hope we could manage to hop over to another universe before ours ends. Anyways main point of this rant, I hope for and believe that it would be Humanity's greatest achievement to outlast this universe and live to tell our tale in another universe and the fate that will inevitably befall their universe too. Once we've unlocked that secret, Humanity can live on forever.
This video conjures up memories of the movie The Omega Man (1971) . "To bury what was dead, to burn what was evil, to destroy what was dangerous. And when you die, the last living reminder of hell will be gone... are you GOD???" And remember "use the time that we have wisely" ~ David Kipping ~
You use science to tell stories in such an impressive and awe-inspiring way. I'm so glad I came across your channel, thank you David.
It took me 30 minutes to watch this video but I aged only 15 minutes. That's how interesting it was.
Nice!
Relativity boooiii
Took me 20mins because unless I accelerate it, his slow speaking drives me crazy.
i aged only one minute because i stopped before that., however a interesting idea, if told by a more interesting person...sorry
lol
When I was a child, 12 to be precise, I used to lie under a tree in our back yard and look out into the sky as it slowly darkened with sunset. I used to think, what if I was on a space ship that just kept going and going and going….where would it go. No I am 73 and I listen to this. And I know. Thank you. This was amazing.
Have you seen the movie ‘Ariana’? It’s a Swedish sci fi movie, based off a book length poem, it’s really good (I don’t want to give spoilers but your childhood thoughts are represented in the movie). It gave me shivers
Whoops, title is ‘Aniara’ not Ariana
Shouldn't lie its bad
Welcome on board.. we are on the earth plane.
That's so cool! Bet the answer wouldn't have impressed 12 year old you lol. Amazing video!
This remains one of the most inspirational, terrifying, and simply fascinating videos on the entire internet! Thank you for this, and for your other works as well!
So I've been teaching myself the concepts of astrophysics for the last 18 months. I've seen all your videos at least twice and now this for the third time, and it has brought tears to my eyes. It conjures up so many emotions I never thought possible from a science documentary. It puts everything in perspective and makes me wonder why people aren't celebrating this window of opportunity we call life each and every day!
As someone who teaches astrophysics, maybe you can either laugh at my silly notions or perhaps be inspired off of them, as I am not considering the possibilities of what we currently know, as I expect that what we know in billions to trillions of years from now (if we make it that long) will be far, far more advanced than what we know now. We only have record of humanity's writings within the past 6,000 years or so give or take. And civilizations were only formed in the hundreds of thousands of years ago range. Humanity hasn't even had so much as 1 million years together as a civilization, not even close. And humanity has only even had about 200 years to play with cool new technology like electricity. That's not a lot of time, and yet we have this expectation we should know everything by now when that couldn't be further from the truth. SO i'm sorry to preface with all of that but felt it was important to say. But my main point is this. Could we not outlive the universe? Is it impossible for us to do that? perhaps under our current understanding it might be, but I believe there's most likely a way to bypass the ending of the universe. If we believe multiverse is a thing, there's many variations of multiverse. Depending on the variation, why would it not be possible to simply travel to another universe before yours ends? Additionally, can we not figure some self-sustaining method without natural causes to generate energy to sustain us after the universe is gone until a new universe appears, even if it takes quintillions to unspeakable amount of years where time is meaningless at this point? The big problem with that posit is the fact that our current understanding would state energy would become a problem in the ending of the universe, but perhaps we don't understand the full scope or we can bypass some limitations in some way? All I would love is for humanity to outlast this universe and make it to the next to tell our tale about our pale blue dot.
Hey! Thanks so much for tuning in everyone! This one took me quite a while to put together so I hope you enjoyed it and I appreciate you taking 30mins out of your busy lives for this. It’s cliche but please do like, share and subscribe to help us grow and keep improving our content through your support. Let me know down below what topics you’d like us take on in the future!

This channel is going to be huge
This is the second video of yours that I've watched now, and I'm impressed with your narration. Keep up the good work, and I'm sure your channel will flourish! I have to say though, you explained really well how lonely of a place the universe can be as you go further out into space/time towards the big freeze!
Thnks for your work . Best thing ive watched in yrs. Love it
What ?! 30 minutes ?! Guess i experienced some time dilation. ¯\_(ツ)_/¯
Attractive in so many ways.
The ending when he said “theres no better time to be alive now “ that just woke me up to reality
Make each day count
No, It can be better time to live in our Universe. Just use the artificial cosmic superintelligence that can destroy and recreate any number of Universes possible.
Da
you're not done. there's so much work to do. you'll keep getting woke up over and over and over
And then there is 2020.....not so much.
For all the rewatchers of this masterpiece, welcome back. For first time viewers, we’ll see you again soon.
Wow. Just wow! I have no words to explain how I feel after watching this. For the entirety of the video I was spellbound and the ending was so emotional. That line and the quiver in the voice saying 'sometimes when you win, you lose' really got to me. Many thanks to this channel. Timeless!
Watch the film What Dreams May Come starring Robin Williams, if you want some context for that last line (and it's really an excellent film).
Watched this again today - maybe the fifth time. I would gladly nominate this video as the best on KZhead. From beginning to the epilog.
That makes you a cool junkie. Slowly becoming one myself.
What exactly is your qualification? Did you graduate kindergarten yet?
A seriously under appreciated gem. So factual. So cerebral. OMG, I feel my mind getting smarter and my hair growing. Ok maybe not the hair growing part 😜
I agree!
The only real competition for "best video" would be other Cool Worlds videos.
The most tantalizing storytelling I've ever heard in this subject. Such a bittersweet storyline.
Here's something even more tantalizing. kzhead.info?search_query=thunderboltsproject+black+holes
The problem with this video is that Einsteins theory proves wormholes are very much possible. Not sure where this guy got his information.
@@k2r1ce56 that would violate Hawking's causality protection conjecture, I think Cool Worlds did a video about that already
saeid-hn Yes-bittersweet. Another comment mentioned a saturating kind of sadness. I agree.
Bronwin Draney Bronwin, I went there and don’t understand what you mean. There are no wistfully elegant, emotionally intelligent narrations about black holes of the caliber being cherished here.
This is just insane. Not just the universe but the amount of knowledge, detail, and explanations in this video is shocking. David is a special human…. that is for sure. This is one of the greatest videos ever made. Thank you, sir!
Unfortunately, this is pure science fiction. The "proven" "scientific" ideas --- equations, mathematics, methods, etc ---- to travel as he described here are 100% pure science fiction. Zero of it will ever be science. In real life, on large objects, getting them to go 1/2 of ONE PERCENT the speed of light will be close to impossible because of fuel problems, because of human frailty (through evolution, we've evolved to be extremely fragile, physiologically), and because of space "junk" (tony atomic and molecule and larger things that fly really fast every which way in the "vacuum" of space). There are many other problems --- in the 100% inhospitable "vacuum of space" --- but those three are among the Top 5 biggest challenges.... as to why HUMANS will never be able to build giant ships that go beyond 1/2 of 1% of the speed of light... so, again, the speeds "achieved using real science ideas" here is just pure thumb twirling by tenured professors and researchers who have hard core science fiction stuff going on in their heads. And THAT IS GOOD for us; it just is NOT science. The theoretical and engineering DIFFERENCES between (#1) lobbing a few tons of objects (of mostly electronic gadgets) into local space --- or even further afield --- and (#2) sending dozens to hundreds of humans on spacecraft weighing hundreds of thousands of tons that could grow its own foods onboard, traveling at 5%, 30%, 50% the speed of light, etc..... are in ORDERS of magnitude humans will never conquer, whether in 50, 100, or 5,000 years... Sending highly advanced sturdy, lightweight robots... sending pure uploaded human DNA (to hopefully be assembled by advanced alien species hundreds to thousands of years into the future)... or sending decently large and slow but well constructed spaceships that contain a few dozen humans that could reach the Alpha Centauri system in a few generations time.... and do that in the next 200 - 500's years, very possible... Anyway, I grew up on hard core science fiction --- having read over 2,000 books, since my early teens, from the gold age of science fiction of the 1930 - 60s... to the present --- so when I come across hard core science fiction ideas, I immediately spot them. Talking about using "matter-anti-matter," "anti gravity," "dark matter," "dark energy," etc as fuel is PURE Star Trek "Dilithium" stuff... again, that's NOT real science.
We are lucky to be an entity of the universe that's conscious of itself. This channel is a gift to humanity's pursuit of reality, thank you ever so much for these videos
That was the best KZhead recommendation I''ve ever received.
I agree. I found this video absolutly facinating
Right!! I made a comment that said "This deserves an award!!" like an Emmy or something youtube style..lol! I love his videos!
Dark Energy, Entropy, and The Center of Universe - with Dr. Neil Turok m.kzhead.info/sun/fLmvfruPe3-of2w/bejne.html
Some of us found it by searching, not because it was suggested. We are more gooder!
This is one of my favourites, it boggles the mind and makes you feel impossibly small compared with the mind numbing vastness of space. Well done David, a beautiful and thought provoking film.
The universe will never end since it never had a beginning. The universe will never forever be an empty black void; even if the universe keeps stretching thin and reaches to cold temperatures. I'm sure that there will be something that will spark it back into another big bang. Don't forget, we don't know absolutely everything and there's even studies suggesting the universe contracts and expands.
Professor Kipping is such a good narrator, that i kept listening to him long after i stopped understanding what he was talking about.
i could barely keep up man

Weird, I’m watching this at 9:14am, Monday morning. Why not?!
Wednesday.. 8 am
Weirdly enough… i feel like I was in the spaceship my mind travelled while he tells his story. I started freaking out because I’m conscious enough to realize that’s some scary roller coaster trip to be on.
If you’re battling with insomnia I recommend this video for you. You will sleep, wake up and sleep again and yet this interminable voyage wouldn’t have gone anywhere. David’s voice is also very soporific. A complete package for insomnia.
I thought I was the only one!
ever get that feeling of hopefulness and existential crisis at the same time? THIS is it.
Totally agree... This video makes me cringe. Especially because I have heard about all this and more from a recorded, unedited book from the sixth century. Damm.. I am shivering man.
Hahaha.... That's exactly the same feeling Progressive Metal and Rock gives you🤓
@@mishafinresko3145 What does it mean
There is a solution to this. Don't move through space, have space move through you.
@@justin60222 thats deep. i like to ponder to that thought when im high
David's voice can really hypnotize. It's incredible how slow and comforting he speaks of a universe so incomprehensibly larger than us, insignificant grains on an insignificant planet.
Agreed, which is why I wonder Why we fight and argue and waste precious time and money on insignificant things.
@@petercermak4095 Because we are the dumbest critters in the universe!
Less than insignificant. It’s interesting how the astronauts have a profound change in mind set when looking back on the earth from orbit. Everything in society seems so petty.
I disagree. Earth is hugely significant. To all of us. There may be trillions other civilizations living on their own planets, moons and what ever, in that sense we are just one. But everything that exists on Earth, is still unique. Edit: what I mean, the lifeforms we have here, and the cultures are unique.
he is handsome too
Beautifully done. It reminds me of a novel by Poul Anderson called Tau Zero, which had a more optimistic ending. A ship capable of indefinite acceleration eventually finds that the universe stops expanding, and begins to collapse, resulting in another big bang. The ship lands on a planet in the next "iiteration".
Thank you David. The word "awesome" falls infinitely short to describe the workings of our universe and what lays beyond.
Looking at the world through your eyes must be terribly painful when you realize that 99.999999% of the people around you don’t realize how precious and fortunate we are
Don't blame them. Most people ---- outside of tenured astronomy professors and a few souls living off of the grids ---- don't have time to sit down to ponder about stars, giant filaments of galactic structures or even the millions of small molecular & atomic entities moving inside a single human cell, doing wondrous things for the human body, from cellular reparation to red blood & white blood cell activities to feed tissues & organs with oxygen as well as to fighting off foreign infections. Or how most telomeres slowly wear out, from aging and stress, no longer able to protect the ends of the chromosomal structures, after many cellular divisions and, as a result, we die... Human deaths are basically cellular deaths, in large scale... due to crucial cells unable to fight off infections, genetic disorders, or a combination of both... Some life forms, like some jelly fish like Turritopsis dohrnii, for example, could "revert" at the cellular level to earlier stages and restart their cellular growth like babies again..... & theoretically, there's nothing except being physically damaged or eaten that'd stop them from living "forever..." Anyway, most humans are too busy, too locked into their pursue of making a living, from those barely getting by from day to day to those like the Buffetts, Gates, Bezos, Zuckerbergs et al who're raking in tens of billions of dollar every month, due to tens of millions of army ants slaving away, taking turns doing 24/7 work for them. THAT is why mot of mankind's 7.8B people are still believing the same Stone, Iron, and Bronze age tribal fairy tales our remote ancestors believed in, in those millenniums in the past. When you struggle so much, so constantly, with so much to gain or to lose in material comfort, or in position of power.... you don't have quality time to reflect on bigger, smaller, and far away natural phenomena that are not easily pictured like the typical stories and pictures of angels, saints, holy prophets, divine entities, etc. engaging in movie-like activities for you, against you, or "up there" in imaginary paces where your beloved ones who've died have gone to, etc. We humans still are a relatively primitive species, even if the work of a few hard nosed, not easily swayed eccentrics, over the last 3,000 years, have shed some lights on Nature and some of her cycles, patterns, behaviors, and constituents...
I"d say your off by about @least 30%.
@@kiabtoomlauj6249 Disagree, Those fairy tales that you talk about taught us civilization and led us to a civilized complex humans. The events that you think don’t fit according to our modern scientific understanding isn’t enough to provide proof that it didn’t occur. There has been many factors which has been verified , which also doesn’t fit with our scientific understanding. Try researching Science and God. According to religion everything has been created by God that includes everything even the laws of causation. Lets assume those events did happen in our ancestors” How would they notify the later generations??” Through religion of course there were no video cameras or computer existed. How would you explain cosmology and other scientific proofs mentioned in a book (Quran) more than 1400 years ago??. There is so much we don’t know and no it’s not our responsibility to know but rather believe. Why do we have these emotions that have nothing to do with living?? Like Right and wrong, Good and evil, Believe and disbelief, Birth and death, Love and hate, Life before death and life after death. Most key things exist in pairs. Why is that ?? We have two major organs in our body but only one heart?? There is so many questions are unanswered by science? Science only describes something that exist in way. It doesn’t describe why it exist. Why out of billion other possibilities that our fate chose the possibility of life?? Even within those billion possibilities there were billion more possibilities attached to it. Seems like a perfect design so we can come and enjoy. Our consciousness is the answer to everything. Use it wisely!!
@@mehmoodali6759 Science isn't as new and strange as you make it out to be. People were writing down and recording straight facts though observation two thousand years before anyone ever said jesus christ for the first time. Religious dogma is not a device for recording vital information about the universe, and has in fact been used as a weapon to destroy knowledge not preserve it.
I couldn't put it better, I can feel his pain knowing all that and be 99.99...% sure you can never actually see the event horizon
Me before this video: "Oh awesome, a science fiction-y video! Time for some lighthearted space travel fun!" Me after this video: *existential crisis*
Exactly the same here.
you know, existential crises are like traveling to the edge of the universe. they're both best when experienced with a friend.
It's okay. You'll be fine. Just breathe.
anyone wanna see something really depressing? watch - TIMELAPSE OF THE FUTURE: A Journey to the End of Time at - kzhead.info/sun/qKhtmd6te3-LhHk/bejne.html. its both the most depressing and strangely beautiful videos i've ever seen. it will either leave you sad or INSPIRED! it will make you ask - why on earth do humans continue to listen to an elite that's so petty and greedy they want nothing but to divide us, pit us against each other so they maintain their domination over us all. there are more important things than MONEY, materialism, power and dominance! why do we continue to allow the elite to create a world that COMPLETELY distracts us from THIS FACT! this world the elite has created corrupts are natural instincts and skews our very view of reality. anyway, its a cool flick, check it out.
Can I ask what a " existential crisis" is about?.... I just love stuff about space. Can you help me with your knowledge please?.
David Kipping’s videos are brilliant in every way. From the sound of David’s voice to the words he uses in his narration. There is nothing that compares to his erudite and mesmerizing presentations.
4yrs later and almost 200 videos this video still gives me some existential dread. This was the first video I watched on your channel
By far the most scary yet satisfying and intriguing video I have ever watched on KZhead and I have watched millions of them. Thanks for the perspectives and making the intergalactic travel as humane as possible.
No , you didn't watch millions of them 🤣 btw, there is another great video kzhead.info/sun/iK9mkduLgpyhZas/bejne.html&ab_channel=Spark
Don't be scared, that void will come to us muuuuuuuuuuuuuuuuch sooner.

@@derekderek2570 Definitely won't be sooner for us.
@@rupakrisal990 So you can watch this youtube video but can not watch that youtbe video, interesting.....
This video makes me sad. It’s so calm and so melancholic! And yet I come back to watch it every now and then to remind me that my problems means nothing in a grand scheme of life. We are nothing but a drop of water in a endless ocean 😔
Yet your problems mean everything to you.
we are all just a ripple in time
And even the ocean doesn't matter much in the grand scheme of things. If there are more galaxies in the universe than grains of sand on earth then the death of an entire galaxy is no more tragic than the destruction of a grain of sand. What is important cannot be linked to a scale of size. Importance has to exist in another dimension that transcends the limitations of our understanding.

@@willowluo950 We're human.
The narration for this video was so harrowing and enthralling I felt as if I'd stepped off that journey myself! I still can't really wrap my mind around the complex concepts that form thought experiments like this, but bright minds such as yours and Carl Sagan's giving us a glimpse into another world, so to speak, is always a fascinating journey! Please stay curious!
speaking in a human manner, with no advertising rush, is delightful.

So original
I hate to be that guy but it's Arthur C. Clarke. Just had to correct it out of some overzeaolus respect for him.
@@nuryuzlucellat I get that...
As classic, beautiful and concise that quote might look at a quick glans.. I beg you all to differ, upon a closer look.. Because if the latter would encounter us.. Before we encounter them.. It would surely spell our utter and complete demise.. And if the reverse, would be the case.. Well.. let me put it this way.. We haven't exactly been alone for very long now, have we? At the top of the food chain in evolutionary terms, I mean.. Apparently, we didn't think to highly of the "others"..
Being alone is terrifying. Aliens may or may not be.
I have watched this video countless times and it still blows my mind every time...
FOR REAL!! Blew my mind the first time I watched it, still continues to blow my mind.
I typically watch it everyday before bed, something about it just truly resonates with me
@@OurDarkestDecadePV same
Yes.
I've seen this video three times now. It's so breathtakingly beautiful and mesmerizing, it takes me around 30 seconds to sense the real world when the video ends. Thank you for this.
I truly have become to love this channel. Since Cosmos from Carl Sagan I haven't been so inspired by astronomy. This episode is mind boggling. Thank you for this great gift to us!
I've been using KZhead since its inception. I can say without hyperbole that this is the best video I've ever watched.
agreed. beats ashens.
Yeah. It's phenomenal.
You are not special because you watched youtube "since its inception"

You’re feeling of sadness was mine, too, Dennis. When I see any truly realistic, discursive modeling of space/time travel and all the breathtaking contingencies and ramifications, I grow almost infinitely wistful! Somehow great distances evoke some autumnal fatefulness, an intriguing, reflexive nihilism. If you saw “Contact” or “Arrival” we probably shared the same version of “and-then” sadness. Thank you for articulating it.
Just try to have a laugh if you can. We're only here for 2 blinks of an eye.
Your pacing and delivery are perfect. I don’t have to constantly go back to hear something again and try to wrap my head around it. It’s also mesmerizing and impossible to stop watching. You got my sub 👍
Started watching this with curiosity, but it made me feel mysterious. At the end I kinda cried understanding that exploring wouldn`t be like living home. Loving & being with loved ones is way more wiser. And just after that when he said "Let us use the time that we have wisely" made me think about everything wisely.
Wow. As I read this comment and your quote at the end. He said it at the same time.
I’ve never felt so simultaneously hopeless and hopeful at the same time
Check out the Quran, Smith. U ain't half shocked yet. I guarantee you.
Our brains can't handle this "situation", we're in for lack of a better WORD. at least not in our current form, shape nor state.
I’ll never forget spending 8 months in jail with Brian Greene’s “The Elegant Universe” as the only real science/physics book worth reading. I must have read it cover to cover 7 times, and although I had a working understanding of astrophysics before that, afterwards I truly understood relativity and it’s implications for aging in space travel. I also got a very detailed grasp of string theory and quantum mechanics, and that experience has given me a lasting passion for this topic. Sometimes blessings are in disguise, truly. This was such a poetic and powerful illustration of time dialation/lorentz factor. Beautiful work.
I say you spent your time in jail extremely wisely.
@@Slaphappy1975 read many physics books since, the black hole wars by Susskind, Sean Carroll’s The Big Picture, Tegmark’s Our Mathematical Universe and many more but there’s something special about Greene’s writing and presentation, there’s a reason he’s one of our science “communicators”, he’s been involved in crucial research related to string theory and has a gift for writing. 🤘
Thanks nick. Now In my amazon cart
May I ask what you did/what you were falsely accused of that happened? I hope you made it through OK.
@@divereric from 2012 2015 I was in a relationship with a girl who got me into doing heroin, and to support my/our habit I was committing lots of theft and I got it caught at my apartment with a lot of stolen merchandise. I’m not proud of those days, but I’m a believer that nothing in life is above being honest. I’m glad I made it out of that dark period. Nowadays I get to focus on the truly beautiful things in life. When you’re in a Texas prison surrounded by (mostly) by people who could care less about intellectual pursuits it puts things into perspective and you realize that you can do so much better. I got out intact, I cleaned up and moved on, but yeah it was quite an experience. Had there been more physics materials or media it would’ve made it a lot easier but it was a strange blessing getting to focus that intently on ONE book. The Elegant Universe happened to be an incredible read. Anyone that’s interested in string theory or gravity should do themselves a favor and read it as well as Brian’s other books cause they’re equally as impressive. Thank you for asking I’m humbled by your question. There’s some great people that have really awesome taste who watch this channel 😎
I’ve been addicted and binge watching your videos since I just found it. 😂 love the way you explain stuff in a simple way for a normal person to understand, thank you!
Professor Kipping, You've been my favorite guest on Event Horizon since I started watching and this was the 1st Cool Worlds video I've seen. You do not disappoint, This was truly an immersive journey through space and time. Thank you and please keep them coming. I'm hooked!
This story left me with the saddest feeling. The story about a journey that makes you leave behind everything that ever was and will be. All for the pursuit of existential meaning, at the cost of literally leaving existence behind. Who would pay such a price!? Incredible topic, flawless presentation, liked and subscribed!
I want to That's will be a good day to day at the edge of the universe
I volunteer; but not for the pursuit of existential meaning. I'd do it for the fun of it. Take that philosopher.
That's the price you pay to find new meaning, and it's always worth it, it's better than wondering all the time.
@@gn9476 Sure, from the comfort and safety of my couch I get the incredibly appealing notions of being all knowledgeable and act as the Universe's last and sole conscience, but really try for a moment to vision yourself being encumbered by nothingness, by a perfect void, in absolute darkness. At least make it a plus one journey, for the sake of (temporary) sanity.
@@L20Nardi The only way I can describe nothing is by thinking about where I was before I was born, but being aware now of a past before me implies I must have existed somehow, the specific things I am constantly drawn to since I was a child (my likes and dislikes) the way it progresses implies I lived a life before this, or I exist with the purpose of continuing something that is not yet finished. In the darkness my imagination creates reality from the hollow void which penetrates me, even without thought, these specific things are there on my path again, impossible to ignore, and the more I accept them, the more things make sense, that I am adding to something greater than myself, something important, that it favors those who acknowledge it, and prepares you for the next step, and no matter where I go in this world, no matter where I am, I am still myself, and it is there, paving a path before me, I am never where I'm not supposed to be, it calculates, and the more I learn to read its code, the more it gives me to bring me closer to it, therefore I am not alone, never, and there is no true nothingness or void, it just seems that way for the things which are not yet, the things which are still to come, have not been assembled by the imagination of ones mind, which means that all that is to come, all that will ever be, exists already somewhere and just needs to be calculated correctly into an organized form, for imperfection requires constant refinement, what's the point of life without refinement? this may be too much information, for to truly understand you must have your own experience of it, and maybe you do, and that's why you are here, to confirm or to progress or to refine, whatever your reason is, I hope that I have helped you somehow, for you have already done the same for me.
This guy so brilliant how he explains about space n etc.. i can literally sit and listen to him all day..Just brilliant Absolute brill..👍👊

i remember watching this on my tv like a year ago and i finally found it this video is probably one of the most interesting videos i have ever watched
What to say....Just mindblowing...saw it at night with lights closed and enjoyed more than i have enjoyed in any movie. Thanks for making this masterpiece and also making everyone realize the beautiful time that we are alive in this universe...so much to see, experience, learn & know...🙏
This video is a master piece.
Thanks so much, it was a big effort to put this one together!
What a load of theoretical nonsense! Sorry dude but people are waking up to the fact that the Earth is flat and stationary with space being a lie. I guess you can get away with doing this when the majority believe it but your time is almost up! People need to be shown so if our solar system is anything to go by when it’s closely looked at then the universe is just a story! Everyone needs to look on KZhead for, ‘Real stars and planets’ It will blow your mind I promise! It’s video footage from the legendary Nikon P900 high powered zoom camera of the luminaries😍 Tesla said it was an electric universe and once you see these images you’ll definitely agree. Or just type in Mars P 900 and tell me you think fElony Musk could shoot his load to a luminary!

This was one of the most interesting videos on how deep space travel I have ever seen. I actually understood about 75% of it! Thank you for doing this video. It really makes you think what is out there!
At the end...nothing... You're welcome...
@@thebringer6216 Yup. Nothing but a huge empty void. If that's all you want to see, just stare into my bunghole.
I keep rewatching this video every few months, usually when I'm around people who haven't seen it. My gf just looks at me and shakes her head. :-) Each time I pick up something new, read a new comment, think about something else. I keep thinking over how it's possible that space is expanding faster than the speed of light. Its mentioned about returning home. After so many years, the ship is your home. Returning to anything later on in life (even if Earth and people you knew still existed), I think you'd end up just wishing to go back to where you've lived your whole life... the ship.
I don't think it's an exaggeration to say this is one of my all time favorite KZhead videos.
You know, I find this video fascinating and, for some reason, quite emotional. It may sound stupid to say it's emotional but the video is so perfectly done, that it brings out a kind of sadness and longing. The music, the way it's explained, the tone of voice used... all these things bring about a longing to see that further distance and a sadness of what must be left behind to do so. Silly, I know but if the imagination is great enough to place yourself in that ship, one can't help but feel such emotions. I'm not sure how many times I've watched this over the years it's existed but every once in awhile, I take this journey and the emotions are always there... sadness and longing. I know it's more than two yrs old but thank you for making this video. It's 30 min I happily sacrifice to see and feel the end of the universe. Beautifully done 😌
Exactly the same emotions are felt by me.
just read holy Quran you will know greatness of God you will be worshiping the God how great this universe
Absolutely emotional and how small are we as Humans and life on earth! Hope humanity can appreciate this every moment of our living lives !
It is just a very stark reminder of how small and inconsequential we truly are
Ya, no kidding. It's times like these I envy future generations. All that we've seen, the advancements we've made in my lifetime alone, are amazing. Makes me wonder how far we'll go or how far we'll fall. It's fascinating, as well as a little scary, to think about. We as human beings have so much potential, it's mind boggling to think about all the ways we hold ourselves back. God, the things we could accomplish if we could stop looking at ourselves as the most important thing in existence. The level of our hubris is astonishing, to say the least.
This concept needs to be made into a movie. The astronauts return to a barren earth...
watch the original planet of the apes?
There is a movie called time trap on Netflix, and tho the concept of how it happens is different, the way the universe appears is almost exactly the same as in this scenario

This was mesmerizing. One of the best videos on YT. Thanks for taking us on a ride to the edge of the Universe. Makes me want to live the best of life on this Earth within our limited time. You are just exceptionally amazing!
Nothing is more humbling, or feels more important and edifying, than astronomy / astrophysics / cosmology. The death of the universe never fails to bring a tear to my eye. I was in tears at the end of this video.
This is so cool but in a terribly depressing way. The things we can never know, its hard to fight the feeling of nihilism when I watch this.
I don't worry about dieing Saying that, don't worry about living, and just live your life, tbh stop watching these types of video, i only use these video's for abstract thinking from the normal boring world The end isnt here yet (yet could be long after your lifecycle)
I was thinking the same like being the first and the last person to see all that wonder. I feel sad after this video. It's so hopeless great work one of my favourites video in YT
It's anything but depressing to me. There are things we'll never know like intelligent life in other galaxies because the distances are just so great. It will probably take another 10 Einsteins and 10 Dawkins before we fully understand the Big Bang, how something came from nothing, and how life evolved on earth.

This was one of my most favorite of your videos so far. Incredibly entertaining and thought provoking. I'm sure I will watch it again. Thanks!
The most hypnotic video I have ever watched. 30 minutes passed as if it was just 30 seconds.
Almost like the relativistic point of view Prof. Kipping explained in the video..
How fast were you travelling?!!
I slept like 4 times
What a masterpiece. I love that sad background music towards the end - it just adds something to the feeling of being alone and lost in the vast scale of the universe. Which we actually are.
it actually means that life has no sense at all. nothing has sense at all if you will. sounds sad but its true

@@viranisco we're all 1 consciousness split into fragments having multiple experiences. Everything is connected mate. Even the Universe. We're a speck of a speck.$
Actually, everything is connected, not isolated.
I've watched this probably ten times. I keep coming back to it. It haunts me.
Brings back memories of Poul Anderson's book Tau Zero, where Tau refers to the ratio of your actual velocity to C, the speed of light. As Tau approaches zero, your speed approaches C and time dilation means thousands, then millions, then billions of years are passing outside the ship. Also Heinlein's book where a scientific foundation subsidized sub light interstellar travel expeditions that with communication provided by telepathy between identical twins. At some point technology develops trans-light travel and the protagonists ship is met by such and returned home decades later.
This is the part that is not intuitive to me I think, I thought I was following the video, but then he describes traversing vast distances (billions of light years) while travelling less than the speed of light, but i would expect even travelling at the speed of light for that to take eg 1 billion years for 1 billion light years distance
I never could wrap my head around " infinity".. now I know why, it keeps running away from us, faster and faster... absolutely my favourite video EVERRRR...THANK YOUUUU
"Infinity" can't "run away". I assume you're referring to movement of observable/finite mass. Didn't watch the whole video. But yeah, "infinity" doesn't have a size, it can't move in any direction because there is no border, however mass within it can.
The way he says "you and your crew" is everything
The only video that i can say is the most important video someone can watch, ever. I knew that relativity and time dilation could cause chaos, but I never knew just how far it could take you. In a brilliant way, in the end, you will have outlived the universe. You would be the universe in fact, since nothing even exists besides you. Somehow this feels like the main quest to life.
This is the exact video I've been looking for for so long, thank you.
Please please go into urban schools and do this presentation! I promise you would inspire some disenfranchised youth to want to explore space. I am dyslexic and I understood perfectly I’m 50 but you made my mind 15! You deserve an award for this

@@AX1A Yep yep yep
David, this video and the smooth calmness in your voice had me mesmerized and hypnotized the whole way through. The way you were explaining the entire story had me imagining that I was right there on the spaceship 🚀 with the crew soaring through the cosmos!!! How you were explaining everything about existence of time itself and not even the speed of light could catch up with the end of time. Or, the beginning of time??🤔🧐🤷🏼♂️? Was mind boggling and bending but also fascinating!!! Best and longest journey I’ve ever been on through the universe!!
Wow, what an interesting and well produced youtube channel. Dr Kipping does an excellent job of explaining these concepts. Why am I just discovering this channel now?? This channel should have been recommended to me years ago.
This presentation not only answered all of my universe related questions it also answered questions I hadn't yet pondered.
Woah that was intense. I’ve never said this about anyone except Attenborough before, but I could listen to you narrate something forever. Maybe even for as long as time itself ;)
Right? Love his voice...
I hope you are good company because I would join you :)
I love you dude. This is amazing. Ive always had a picture of expansion and causal limits in my head and this helped flesh out parts of it. The only part i cant wrap my head around is inertial reference framing. Say you get to the mid way point going 0.99% the speed of light and see the red shift then stop accelerating, youd be at rest and your frame would be the same as the start? Im basing this on all inertial reference frames being at rest from the point of the observer within it. I dont know if that makes sense but some nights i see its all clearly as im falling asleep to lectures beyond my critical thinking and math heh.
This is one of the most moving things I have ever seen, come back to it every now and then.
I watched this 5 times so far, the reality I get from this is why are we fighting for politics, ethnicity, land, religion ... just makes me wanna enjoy life while I can.
Because that's how evolution works... Why can't people understand that? World peace is a silly fantasy that would kill us all. Let survival of the fittest do it's job.
@@anthonyhutchins2300 I beg to differ. Evolution does not have consciousness, but we do. There is no natural selection anymore, we are choosing to change the environment in such a short time without any time for natures to compensate. There is no need for being the fittest where societies are able to fit the ones who have potential. If the fittest means survival of the rich, then lots of potentials are ruined because of religion, politics and ethnicity.
To enjoy life I presume you would need a few things that are provided by others, thus politics will be required.
Nah, just make sure that birthrate is few and that people plant more plants and trees faster than we are to consuming them, as well as animals. We will also have to make sure we don't pollute our environment and waters. If people work together to do this, there would be peace.
The answer to this is summed up in one word..... GREED.....
I always come back to this footage often. It teaches me how small this life is and wonders of unknown
Don't be despondent. Life is massive and it is global. Afterlife will most definitely deal with us another way.
Why do I always get so emotional at your videos when I’m just trying to learn a little about astronomy and physics?😊 Thank you so much!!!
