I was rather surprised when I recently learned that the British science communicator and ex-particle physicist Brian Cox supposedly debunked the Big Bang with a creation story, no less than in a BBC documentary. I had a look at the clip and I think I know what happened.
The Daily Express article with the BBC clip is here: www.express.co.uk/news/scienc...

I think one big problem is that too many people are not ok with the concept of: I don't know
That's not a problem, that's science.
@@mater5930, you are right that "I don't know" is the beginning, middle, and end of science. But what was actually said was "one big problem is that too many people are not ok with the concept." Let's all promote "I don't know" as a valid answer!
@@susand3668 I agree
@@mater5930 You'd think, but many scientists let ego get in the way...
More people are content with Big Bang Hypothesis, which is itself a creationist myth and it's defenders still ignore intrinsic redshift, the thermodynamic impossibilities of standard cosmology and the holes all through GR, including its falsifications and better explanatory models put up in its stead. #toobigtofail somehow, even now...
as someone who just moved to paris, I can confirm "excusez-moi, quel âge a l'univers" is very practical in day to day life
You can always add "Mon aéroglisseur est rempli d'anguilles" - Trust me, I have a B.A. in Monty Python
What ?! Ca vient d'où ?
doesn't that translate to "will you sleep with me tonight, under the stars?" or "will you help me move my couch?" i forget.

"Excuse me, where is the nearest mail box or toilet?"
I am always grateful for ANY person who simply attempts an accurate explanation of what evidence shows THEM…instead of trying to be “sensational” or “all-knowing”…
I saw the Daily Express logo and that answered the question for me.
Yes it really simplified it. A good equation to use is. D.E = a zero point of truth. They are a singularity of pure nonsense.😂😂😂😂
Brian Cox and the BBC - a scientist that endorses political views and thrives on the air of sensationalist publicity, working for an organisation that I would not trust to inform me of todays date!
@@tonib5899 Brian Cox might not even know he works for them 🤣
@arturama8581 I don't understand why Prof Brian Cox is being cooked for this, the guy just tried to explain complicated science in terms most would understand, when you talk about science on a scale like Cox does then you have to dumb it down, treating this as a negative is in itself negative, science can be scary to new comers and we need people like Cox to be welcoming and make it feel manageable, bringing good science to the forefront is absolutely vital especially when considering increasing budgets for stuff like nasa
@@ryanlee6920 But the Daily Express dumbs it down and warps it to the point where there is very little, if any, fact left. It is an absolutely disgraceful rag.
Sabine will debunk you so hard your high school physics teacher will feel it.
LOL 🤣
Well played, oh Zen One
😂😂😂 Also just the sentence "debunked the Big Bang" 😂
Sabine is so cool… you will totally enjoy it when she debunks you. 😂
No. Sabine debunked nothing.
TLDR: A scientist said something salacious and the press ran with it like a Christmas ham under their arm. The more I hear about this type of stuff, the more I think that "separation of press and science" is more important than separation of Church and State.
That's why science communication is a thing. I think it's up to the audience to be skeptical. Good luck with that 😂
Do you think the solution is to eliminate separation of church and press?
The "news" is just another unregulated way to make money, so truth and verifiable information are less important than clicks and eyeballs. So, Separation of Press and Reality.
I remember when journalism was a respected career. Now it's just glorified blogging.
You change that to politics from science and you have a point. The press is needed to convey information, politics warps it to whatever is the party line.
that was the best ad incorporated in a video I have ever seen. She actually showed that she's learned some french. awesome
She's also brilliant, so that makes things easier 😊
Yea her French wasn’t bad, and not to be rude or anything, but her French accent was better than her English accent… in my opinion…
@@mgx2077 Uh ... her English is completely fluent and intelligible.
I suspect Ms Hossenfelder is fluent in French.
@@mgx2077 "Yea"? what version of English are you using?
SO GLAD that you did post this brave open, honest video, and NO NO NO, it wasn't too much at all. THANK YOU SO MUCH, Sabine.
G-Day Brother.
With that constant smirk on Brian Cox's face its clear he knows exacly what happened at the beginning and he is having fun not letting us in on it.
His constant smirks … it’s what irks
never got that smirk thing, but i have noticed it in members of family ( cousin of my mother and his son), so it seems to be some character/genetic thing that can occur.
Just seems to me as if he's passionate about what hes talking about and happy people wanna converse with him about what he loves @ulazygit
Yes, God made it. The smirk is revelation of the method, and the joke is on you.
@@michaeljsullivan524 God could very well have initiated the big bang
I am a francophone and I perfectly understood what Sabine said in French, so she's a good learner! I wouldn't dream asking her to lose the Teutonic accent. It gives a distinctive twist to her English and we are now used to it, so the same goes with her French. Accents are the last thing one loses when learning a foreign language, if ever.
I think weight is always the last thing one loses, learing a foreign language or otherwise.
Leering is what happens at you if you do lose the weight.
I thought she just sounded sexy all the time. Here is the question do you think there is as fine a singer in French as Lea is in German? I have reason to suspect that no one makes music as well as the Germans do to-day in German. À propos Traduit de l'anglais-Lea-Marie Becker, connue professionnellement sous le nom de Lea, est une auteure-compositrice-interprète et claviériste allemande. Wikipédia (anglais) The reason I note this is for selfish reasons. I love to look at the videos of the musicians in all the nations and language to debate who is the best. French music is stellar. Sabrine sounds like Lea. Lea is sexy thus Sabrine is sexy also ❤.
@@josedelnegro46 who asked?
@@JBroMCMXCI I ask. Have you heard of Lea? Sabrine has music videos. I like them. She sounds like Lea or Lea sounds like her. But if you are saying who am I to ask? That has been answered. Yo soy Sancho Panza y Sancho Panza Es una persona ignorante nadie... nada y estúpido. Gracias et merci encore
I think you mean hypotheses or speculation and not theory when talking about what happened before the Big Bang. Love your work. Learned so much from you. Thank you!
I wish there was a lot more "we don't know" out there instead of "here's how it is". Knowing what we don't know, and the curiosity to fill in the gaps, is what drives the best science.
The Daily Express ~ "A right riveting read!" Read ~ "a load of Bollox"
a load of Botox...
The only place to find the Daily Express is in the bathroom, just in case you run out of loo roll.
The British press is a dumpster fire lately. Mind you, the rest of the MSM is not much better either.
What do you expect from a guy named Cox?
All those Rupert Murdoch's newspapers are great for a ton of things.......use it balled up under kindling to get the fire lit then keep feeding the fire with more of his newspapers
As soon as I saw Daily Express I knew it would be a total lie.
I'm surprised they didn't manage to imply that this meant we were in for a severe cold snap next winter and something something, Princess Diana lol
Precisely, The Daily Express doesn't qualify as a newspaper, it's a propaganda sheet for wing nuts and a scandal rag for idiots.

I love the fact that CERN labeled the tubes. CERN LHC. Just in case you were lost inside that tunnel at least you know that you're at cern in the large hadron collider.
It's marketing. We saw it, so donors see it, and your aunt watching a news clip on TV sees it.
Maybe it's so when they are being transported on the back on a lorry, people don't assume it's a supergun and start panicking?
it was also very interesting to me that those labels are slightly worn off. like, who is rubbing up against the particle beam tubes so often that the lettering is wearing off? hmmm
@@JonS But that's just what someone transporting supergun parts would label them with, isn't it?

As one of my favorite science communicators, Dr. Becky, says, "Space is hard. Words are harder."

i like that you question main stream science and keep an open mind like a real scientist must due. Nice Job Sabine
Express and Dailymail should always be ignored.
"infinitely lame" had me replaying that 5 times. you're hilarious, Sabine!
infinitely hilarious
I am not a mathematician, but the idea of infinity as well as proportions or types of it, such as half infinity, is all considered kind of a real thing. Even though that's all basically still just infinity. First of all you need to fully accept that we humans have no perception of it, and that it's fully natural to emotionally dismiss it. The start to see that this way of thinking opens lots of possibilities in science, and especially with physics and time. Also think a second about how time can become infinitely slow around black holes, while it still is there. There is also something with singularities if I am right. They do not actually exist at our point in time, but the idea is that they exist infinitely far in the future for related reasons, if they actually even do.
"The smart thing to do would be to just leave it at that. But that's no fun". Well said.
Ah, The Daily Express. That bastion of truth, accuracy and integrity.
True, but I'd extend that same sentiment to all mainstream media outlets as well. Even the so-called science mags are often full of it.
@@methylene5 whilst I agree, some publications are worse than others.
for the ignorant in comments: "In addition to their individual work, Cox and Hossenfelder have also collaborated on a number of projects, such as the book "Black Holes: The Key to Understanding the Universe" and the documentary series "The Universe: A Journey Through Space and Time." These collaborations have helped to bridge the gap between theoretical physics and the general public."
mmmmm???.........wonderful???
Hearing you speak plausible French is honestly the best endorsement of a sponsor you've ever made.
Thank you for all your excellent videos, Sabine. I fully understand what you have been going through, and think you are now doing very good work for everyone who is interested in science but who are not themselves scientists.
Great video with plausible information, thank you. TS
I think Brian Cox is a very pleasant science communicator to listen to and is generally good at communicating complex ideas simply. He may occasionally be just a bit loose with language, but not to any ridiculous extent. However, he seems to be one of those physicists whose words often get twisted into outrageous headlines by the media and by tabloid science youtube channels. I honestly don't envy him that.
Brian Cox was a Blairite & is a remainiac globalist who believe in nationstate democracy. In other words he doesn't believe in democracy.
Its not a twist. Brian Cox really does use the term "big bang" in an odd way, but, since scientists dont use it at all, nobody has held his feet to the fire over it until now. Sabine is ruthless. Thats why we love her. 😳🔥❤️
@@deltalima6703 For sure, but she's not really being ruthless to Dr. Cox here. She's being much more ruthless to the "science media" that is grossly misquoting him here. She didn't really disagree with anything that Cox actually said.
@@deltalima6703 Scientists don't use the term Big Bang? Try an academic search engine: you will find the phrase in the titles alone of more than a million published papers. BTW Brian Cox is professor of particle physics at one of the World's most prestigious [physics] universities. It seems scientists use the term.
@@deltalima6703: Cox is referring to the observable big bang rather than hypothetical big bang. I don't see what's so odd about that.
Thinking about the universe hurts my brain and my soul. It's so infinitely beautiful and sad at the same time. The endless mysteries and the fact that we'll never ever scratch the surface of understanding and knowing it.
It doesn't seem fair does it. Not knowing and then you die! Damn the Cosmos! 😊
It will probably be dead simple once we understand it. It wouldn't surprise me if you could easily explain how the universe works to a five year old if you just knew how it worked.
your whole universe is the one you see, little piece of the cosmos! a universe to yourself!!
Though we may never know the answer at least find joy in the fact that we can ask the question.

I wasn't a fan of daily short videos at first, but I think you hit a pretty good sweet spot now in terms of length. If the videos are 5-10 minutes long, I don't mind it as much! It was only at first, when they were 2-4 minutes long and 1 minutes was sponsorship, that it was a bit fragmented :-)
Yes, because "The Express" is a reliable source of information 🙃
Super reliable LOL !

Well, not quite as good as Daily Fail...
Was it Eddington who said, "Something unknown is doing we don't know what."?

Thanks Sabine. You are a treasure of sane, educated, thoughtful information. Coated in tasty humour. ❤
I would not make such an inappropriate comment, but some would say tastiness in more than just humor.
Time is the strongest force in the uni An object at rest will not remain at rest if time is allowed
Life = heat time distance. Time is what allows something to come from nothing

"According to this theory, out universe is created in a quantum fluctuation in a field called the inflaton." OK, give me a few years to chew that over....
"In the beginning there was nothing, then it blew up"
You ain't supposed to eat the theory! Have a Macdonald's Sir! ❤
Thanks for this clarification. Brian Cox is not alone in referring to the Reheating following inflation as a Big Bang; IIRC, Ethan Siegel does, too. It is confusing for those of us more accustomed to thinking of inflation following the Big Bang rather than preceding it.
Ethan Siegel (and others) generally refer to this as the "Hot Big Bang". AFAIK this puts constraints on the initial conditions of the early universe w.r.t. size and temperature to explain the lack of certain artifacts (e.g. magnetic monopoles) that would otherwise have to exist, but for which there is no observational evidence
Perhaps he feels lucky.
For a communicator like Brian Cox to use the term Big Bang in a way that's different to the way it's used in everyday life, is positively stupid.
What a banger of a video Sabine 🎉

Thank you for the video.
Off-topic, but hopefully appropriate. This channel is awesome!
Not off topic actually direct hit.😊👍🙋🏻♀️🇨🇦
Hey Sabine, that part you said about singularity arises because we assume space to be smooth and not discrete??? Yeah... that's kinda what Stephen Wolfram has illustrated for us quite elegantly with his method of quantizing space using hypergraphs. He's onto something that turn-of-the-century physicists all assumed to be true (but didn't have the tools to probe).
I am just curious. Other than Big Bang, is there any imaginative hypothesis to explain the redshift of Universe?
There's the idea of "tired light" (Google will tell you more)
Yep. Something called "tired photons hypothesis" or something like that.
Tired light is better explained as time dilation.
@@SabineHossenfelder Sabine, i Love your videoes! I have a question for you: Is it impossible that the gravity we are affected by from sagitarius, could explain the redshift we are observing from objects outside our galaxy cluster? That everything isnt traveling away from us, but that its an effect of being trapped by our own black hole? Im not a physicist, and I realize Im probably provably wrong, but I would love to hear your perspective on this and why It might be wrong. Thanks
@@SabineHossenfelder (we want you to do a video about it)
"infinitely lame" i can't stop laughing!!!
Thank you for promoting Babbel, Sabine. You (and your discount deal) have encouraged me to finally start learning French. It's been easier than I expected because Babbel hasn't been picky about my pronunciation.
Very interesting Sabine. A quick question: As space expands into the universe, could there be galaxies that are so far away from us, so their light would never reach us?
I'n not Sabine, but i can answer that. The answer is yes. There is a limit on how far away we can see, because the speed of expansion becomes faster than the speed of light after a certain point. That's not in contradiction with general relativity because nothing (i.e., matter and energy) is moving faster than the speed of light in their own frames of reference. The set of all things we can see is called the observable universe: it's a sphere of 45.7 billion light-years radius centered on us (of course, if there are alien astronomers in another place of the universe, their observable universe would be also centered on them)
As soon as I saw that the headline was from The Express I knew where this was going 😉
“Well, that’s no fun!” Is the thought before every physics theory.
And every physics test I've taken.
They have fun at our expense, having to learn it and take tests about it as though it's serious science. When their theories are proven wrong, we don't get a single apology for being jerked around!
"Well, that's no fun!" Is the thought before every tax season knowing they fund garbage like this instead of things to actually improve conditions for people.
Thank you for sharing your time and work Sabine, if a caveman such as myself can get something from this, and I can, so great job communicating effectively, peace
Those theories always remind me of the stuff I made up as a kid to explain my lego spaceships that I built while watching animated series. "This is infinity fast, so everything that goes faster than it uses atomic energy magic to convert infinity into more speed, like it's two times infinity now."
There are different sized infinities
@@NotSoNormal1987That's true, but not remotely relevant.

I love the way the analogy of the water drop was used, where the drop tapers to infinity, yet the actual source, the tap, is in plain sight. 🤣
I think she said the tube of water doesnt become infinitely thin because quantum mechanics trumps fluid dynamics.
@@deltalima6703 My point was the source of the water drop... the tap.
To my understanding the analogy, implies that we are living in a universe that dripped off of something, and we'll never know of what ...
@@stefaandondeyne Agreed... maybe there was a source, but we can only see as far as the single point where it was launched.
what is this meant to mean, it's an analogy for singularities not the universe. And the tap just moves water from one place to another so what does that imply. huh
I knew you before i knew brian cox. You have done a better job spreading science and knowledge in my opinion. Thank you ❤
Good explanation!
"We don't know." So much more satisfying than, "Your question has no meaning," which I have heard supposed experts say.
I am sure that refers to asking "what happened before time?", which has no meaning. It's like asking what is at 91 degrees north. It's beyond the scale, and so the question has no meaning. To ask what is outside space-time may be such a question. Saying you don't know is also a good answer, but there are a lot of examples of meaningless questions that include an impossible premise for example.
Questions only have no meaning if they are obviously self-answering.
Some questions have inherent assumptions built into them. Examples of such questions that are NOT meaningless include leading and loaded questions. Other times, the bult-in assumption simply makes no sense. "How many angles can fit on the head of a pin?" depends on if an angel occupies a finite amount of physical space and, if so, how large a head of a pin really is in comparison (do we take a statistical average all pins in the world?) Just because a question is meaningless doesn't mean it can't have any value. "What is the sound of 1 hand clapping?" is a well known *koan*, used in Zen Buddhism to challenge rational thought.
@@LiveFreeOrDieDH Single handed clapping is possible, by whipping the four non-thumb fingers around so they slap the palm hard enough to make a sound. It sounds like two-handed clapping done by someone who has only barely learned to do so: weak and irregular. Anyway, I hope this doesn't ruin Zen Buddhism ;)
@@Antares2 Well, time's a funny one. Either it's infinite in both directions, or has a "start" or an "end". But for time to "start" is a pretty weird notion. And I don't blame anybody who'd ask what happened before the "start" of time. I mean, "start of time" is circular, as far as I can tell.
If you’re going to Paris, can I suggest you memorise; ‘Excusez-moi, pouvez-vous déplacer votre tracteur’, you may need it!
I asked GOOGLE's Bard, and here's what it said: The concept of "before" the Big Bang might not even be meaningful in the traditional sense. Time itself is thought to have begun with the Big Bang, so talking about what happened "before" is like trying to describe what's north of the North Pole. Our understanding of physics is constantly evolving, and it's possible that new discoveries in the future could shed light on what happened before the Big Bang. So, while we may not have a definitive answer to your question yet, the quest to understand the origins of the universe is one of the most fascinating and challenging in all of science. And who knows, maybe someday we will be able to crack this cosmic mystery!
As we are finite, our perception is constrained by our very narrow frame of reference, we live, and we die, and through this, we may forever struggle with the concept of eternity.
My theory: Before the universe, there was Nothing... and then Chuck Norris roundhouse-kicked Nothing in the face and told it to get a job.
Gold nunya!
One of my favorite Brian Cox quotes (at least I think it was him) is “Nothing doesn’t like to exist.” (in response to the question of why is there something instead of nothing).
What does a rock dream of?
If nothing existed, it would in fact be something by virtue of existing. You’re welcome for the bit of sophistry.
"Something" won the coin flip. Metaphysically.
It's the natural curve evolution to shear entropic radiation resonation waves. We know literally everything in the universe has it's paradoxical opposition. The fact that we can make any choice or have distinction between inverse properties.. entropy wants our disorder to permeate and refract into nitrogen jello or plasma without thermodynamics.. but we are here, partially aware of this, evolving everything scope to human existence towards curving our destruction. We are the natural evolution of resonation currents trying to shear the radiation waves they needle cast to phase vibrate through. Just think of the universe as a neutrino ocean and pay attention to fluid mechanics/dynamics.. curvature into spheres is the perfect inverse skirting of resonation pressure attempting to squeeze things into diffraction after loosing their coupling, entanglement, attraction forces/reactions. Because they weave through paradoxical sets in a looped system.. it can only expand to evolve together in Ying yang transference across turbulent exchange into strange attraction. So like the train in the movie "the core" .. no matter how much energy pours in or how much one side jumps to gain relative to the other.. they refraction and bifurcate waves and vertices, Vortex and supernova, fusion and resonation pulsation field coupling to only strengthen eachother. Over a Lorenz strange exchange and paradoxical flips
@skipper2285 naw the opposite. Look up strange attraction and the von Karman Vortex streets. Dynamical systems mean they ebb n flow but any gain diffracts into resonation harmony in Ying yang over paradoxical flip. It's why we are/everything is expanding
Love how Sabine smoothly segues from Brian Cox to language to Babel.
You're amazing, Sabine.
A few years back I commented on a video regarding a similar topic and said that from what I can observe, everything around us is some sort of oscillation or waveform. So why shouldn't what we call universe be a cyclic expansion and collapse? I got laughed at and I still can't explain why I think that other than my observations of daily life.
There is some that think that theory is one of the explanations, they call it the big crunch when it contracts. And if people laugh of that they are just idiots... But as it is now parts of the universe we can observe is moving away from us and is already moving away faster then light speed can cover the distance and it is lost for us forever (that is called the particle horizon). So for now it seems that this universe we live in will not be able to contract ever again.
The latest observations suggest that it is likely that the universe will eventually contract. Philosophical intuition and logic tells me the same thing as it tells you, but experimental evidence is needed. What is expected is that the dimensions can only be those that we observe since they are an abstraction of the orthogonal directions from a point, from that reasoning and knowing that nothing can arise from absolute nothing, what can be deduced is that space-time has always existed and will always exist, with local Big Bounce cycles probably. I am of the opinion that what we call the Big Bang can be described as a white hole and what we call the Big Crunch can be described as the maximum density black hole that is incapable of further curving space and undergoes a transition towards a new white hole, or Big Bang.
Search up Conformal Cyclic Cosmology
It's not at all a new idea, the Hindu idea of the "days and nights" of Brahma goes back thousands of years
of all the theories for what happened before the big bang, eternal inflation is the most pleasing to my brain. Would be interesting to know if it could ever be verified through observation?
I believe there is a certain type of polarization in the CMB, B mode that if detected would make inflation more likely and rule out alternative theories such as the cyclic models.
Eternal Inflation is eternal into the future, but presumably finite into the past. That's why Sabine said the Eternal Inflation multiverse had a beginning at a finite time in the past.
Something I've been thinking of a lot is what if it's not expanding but instead shifting like water. Instead of it having a beginning it just "is" along with all of the stuff within it which tends to gravitate to each other overtime. How it behaves now and how we imagine it could've started seems to have a disconnect. Galaxies collide with each other often and/or move apart, just constantly moving in different directions like a trash pile in an ocean. Gases that also exist in this space gravitate to each other until you get nebulas and the process of creating matter happens on its own. It makes much more sense to me that the universe just always was and the process for creating stars had the by-product of creating other materials. Like we know how stars are made and yet we assume it all happened all at once but also took billions of years before looking like what we understand now. It would be more consistent if the entire process took billions upon billions of years rather than part of it and then BANG
Very well done clarification
Well, part of the problem is that 'Big Bang' is a terrible name. At best, it was a super tiny event and there was no 'bang' because there is no air in space. Also, the theory doesn’t adequately explain certain aspects. Why 'Big'? How did the 'Bang' happen? It's like naming a theory 'apple theorem' and then discussing orange juice. Moreover, what kind of theory requires adding 95% of unknown substances to make it work? That's a 20-fold error. It's akin to a child claiming to have two PHDs after the first year of school (the additional 19 being 'dark education'). So, rightfully, people question if the theory's name is wrong, what else could be? If you need to add (fake it to make it ) 95% material to fit observations, it's not science; it's prophecy.That's exactly it. This is precisely why a Priest read the Bible and formulated the Big Bang theory. Just like other observations, such as everything appearing to orbit around us, leading to the belief that we are at the center of the universe.. It's astonishing that people still refer to observations as facts, much like those who claim the Earth is flat because, based on limited observations, the horizon appears flat. The Big Bang theorists are, at best, like divorce scientists who conclude the main reason for divorce is marriage based on observations alone. Without mathematics, it's not science; it's philosophical speculation. Mathematics clearly shows that 5 does not equal 100, and it's time to abandon such religious-like beliefs and seek better theories.
I love how she properly writes sponsors into the video script, almost as rare on KZhead as her honesty
Absolutely. And I think endorsements like these should be far more expensive for those purchasing the ads because they're just so much more effective.
6:38 😂 the delivery, beautiful.
I am glad Dr Hossenflelder and her team, are here to put things in perspective. We just don't know, a refreshing disclosure. However that is no reason not to come up with alternatives and theories, which Dr Hossenfelder mentions.
1:40 I've never before heard anyone explain the big bang using this equation before, that's great
also water drop example!
Brian Cox has this air of mysticism that really, really made me appreciate KZhead and the regular scientists communicating on there.
Telling everyone how full of shit he is.
An air of mysticism? He looks like the epitome of a nerd... If that is your air, you can find it easily near any university.
Some small energy ya got friend!@@ozymandiasultor9480
@@ozymandiasultor9480 Nah, I agree with Fjord. The problem is these long form documentaries where he has to travel to India and Egypt (using Orientalist type tropes) or South America where he writes in the sand, spending tens of thousands on their production budget, when he could have stood with a blackboard behind him and said more in two minutes than in the entire 45 minute show.
Oh come on. This reminds me of some historians going on amazon trashing a popular science history book. Cox makes these programs for the masses and people like me have learned a great deal from him and enjoyed doing so. If you want more, there's other sources, but for most people Cox will do just fine and it should be shown on TV regularly.
I like your new intro :)
"its not a very popular idea probaly because the entire point is that its infinitely lame" got a good chuckle from me
I would like to hear Sabine's thoughts on Pernrose' cyclic conformal universe.
She already made a video about that kzhead.info/sun/fdBmmd2tiqlvfoU/bejne.htmlsi=EGnAHFNlEA9Ai2KB

I would guess pretty much what she also says here about eternal inflation: we don't know. Interesting theory that we haven't proven wrong - which you can say about just about any of the early universe/before it theories, because we just don't have any data to speak of.

In one of the Dr Who audio plays the Big Bang was simply a misfire of an alien spaceship firing up its engines creating our universe.
Seems more likely than the singularity
Goofy piece of writing, that.
@@BalBurghit's Doctor Who. That's a requirement, lol! After all, one of the 5th Doctor's stories (the one where Adric died, for Whovian timeline clarity) had a spaceship crash into the Earth, about... 65 or so mya. Not that pesky asteroid that left the big hole in the Yucatan about that time that got such a bad rap. 😂
City of Death? Mysterious link with Sabine learning französich, eh?
That's really stupid
Physics is when you use some math to create a model that approximates recent observations. I attended a lecture by the guy who hypothesized the big bang years ago, and he now refutes it himself saying he now believes it is a big oscillation.
It's inherent in science to ask "What caused that?', but perhaps somethings were always there and will continue to be forever.
True: God!
His name is Jesus.
Sabine, I have not understood why you say that eternal inflation must also have had a beginning at some finite time in the past. My understanding of this theory is quite limited, but what I get is that it should, on large scales (much larger than any individual universes), more or less resemble a de Sitter model (spatially flat with Omega_Lambda = 1). Under these conditions the expansion law is a pure and simple exponential, it does not admit any beginning or singularity and more in general there is nothing special about any point in time.
Oh I hate it when journalists sensationalise basic analogies or hypotheticals into literal things
I KNOW the "big bang" has been debunked and disproven since the 70s
Cosmology has always made my head hurt.
Always interesting watching “historical scientists” squirm to maintain their grants discussing events they do not, will not ever know or understand 😂
Thank you. I’m not scientific, but I enjoy listening to you.
I think "Scientific" is a direction - not a state of being.
Don't forget we are all made of stars! :)
no, i am scientific and i know what he's talking about @@DeclanMBrennan
sorry to say but if you boil a kettle at all you're a scientist. cooking is science and i don't mean domestic science i mean actual science, you conduct an experiment and if you're lucky you get dinner out of it. you are an artist too, if you can make a mark you're an artist - don't ever exclude yourself from the human race. we are all journalists too - check out the first amendment.
@@DeclanMBrennan boiling a kettle is literally doing science. it just takes longer with a bunsen burner.
I love Brian Cox, he was amazing in Succession! 😜
You should see Stella Cox, she has a lot of movies.
Sure, but he knows almost nothing about astrophysics...I mean that iteration of Brian Cox, the old dude from Succession.
Oh, and in Oppenheimer!
@@fredrik241 haven't watched Oppenheimer yet, does he play the bomb?
@@synystera no, the warheads got together and signed a petition complaining he would make them look small.
Sabine’s chair - in the advert at the end of the video 8:20 - looks extremely comfortable. Where can we buy this excellent chair? Someone ask Frau Hasenpfeffer, please!
I think the two most current theories of which I'm aware are by Laura Mersini-Houghton (author of Before The Big Bang: The Origin of the Universe and What Lies Beyond, July 2022), who proposes that our universe is part of a multiverse created when the cosmic wave function resolved at different energy points across a string theory "landscape" - and the other by Thomas Hertog and Stephen Hawking (author of On The Origin of Time, 2023) which proposes that the universe resolved from a quantum state due to our observing it backwards in time (given that by Einstein's equations the arrow of time is bidirectional). At least, I think I understand these two theories that way. Each has given a presentation on their theory at the Royal Institute as well (one can find the videos on KZhead). I would be very interested in Sabine's take on both of them.
"Take a super simple example of a singularity". No, I don't think I will. Not with my brain.
The singularity, is when your equation says you have to divide by zero to get your answer.
I've always liked the comparison of "asking what was before the big bang is like asking what's north of the north pole." It might not be right if there's all these theories out there about what came before, but I think it gets you in the right mindset to think about time and space as intrinsically connected. There's all sorts of interesting questions that come out of it, like how do you build a frame of reference that doesn't consist of space or time? What is the universe expanding into? Does that question even make sense? Mind boggling stuff to think about and it's kind of amazing that us pink meat apes can even begin to think about it.
Yes I remember a physics teacher saying the universe is only expanding in our 3D world and contracting in a higher dimension, I'm not really qualified to know if that makes sense either,just his theory I suppose
The only thing that detracts from this video is the obnoxious set of the compulsive, obsessive hustle culture's sales ads which limit the universe to how can I jack off for money in my little microcosm.
That’s because we are not just “pink meat apes” that just stumbled on fire and electricity by accident, our consciousness is also not generated by our brains rather a receiver, that’s why we can even ask such questions. I doubt that “animated matter” with chemical reactions(which is what we are portrayed as being) can think such mind melting topics especially when this gets mixed with theology( btw theology and science are both asking the same questions just in a different was like 2 different sides of the same coin)
@@Jack-gn4gl I'd be lying if I said I understood it any better but to me that explanation falls under the "push it up the chain" category that Sabine was talking about. If there's a higher dimension then where did that come from? How can it contract if it doesn't also have some dimension that represents time or space? It's mind boggling, the more I think about it the less sense it makes. Clearly "Something Happened," and we're all here today, but the idea of "Something Happening" without time or space existing doesn't make any sense, let alone "everything happening all at once." Who needs to quote Brian Cox out of context when thinking about the reality is enough to destroy my brain...
Before big bang there was small atomic universe which expanded to our current universe which cooled down now we have Earth habitable planet
A prize for the copy editor who wrote that headline. This is the third WTF? feature I've encountered responding to Brian Cox's supposedly "debunking" the Big Bang 😂
When we finally find aliens Humans: So what happened before the Big Bang? Aliens: Wait, what, you mean this round is your first one? Wow, that's so unheard of
