What lies at the edge of the Solar System? Far beyond the orbit of Neptune and the Kuiper Belt, deep into interstellar space, we find a vast, thick shell of icy space debris. We have never seen it directly, but we know it exists- because it is the source of the most distant comets that we see entering the Solar System. So why is it there? Today we'll find out, in a new episode of #OOTW

After watching countless space videos throughout the years, I’ve become more familiar with the huge scales of distances between objects because I hear them so much. Don’t get me wrong, they’re still insanely and incomprehensibly large, but I wasn’t shocked. But hearing just how big the Oort Cloud actually is blew my mind. The fact that Voyager I has traveled roughly 7 hours worth of light speed of distance and the Oort Cloud extends for 18 MONTHS worth of distance is absolutely insane.
Voyager is around 22 light hours away
Me too bro cool huh
It’s going to come back as V’Ger 🙃
@@JJ-fq4nl lol excellent reference
Part of me wants to believe one our space probes makes its way into another solar system many thousands of years later to be discovered by a space faring people. Long after we’re gone, our existence will remain in what we have left behind
I’ve only recently started to truly appreciate how vast the greater universe is. But this video gave me a whole new insight on just how vast our own solar system is!
It really didn't. Look more.
Watch his "End of the Universe" video if you want a real perspective shift.
Well, think of this: if you shrunk down our solar system to the size of Earth, then Earth would only be about the size of a pea.
and Loader's Number makes the sizes in these videos look absolutely insignificant
@@matthewviramontes3131 no smaller probably
Incredible to think that we peer right through the Oort Cloud every time we look at our neighboring stars, it’s an invisible wisp of matter that barely registers amongst the brightness of the stars. Thanks for making this video, it was particularly good.
no the main this is how MINISCULE humans are and the scale of astrology. Silicates and metals are cooled meterials from supernovaed gen 1 stars!
@@aaronmcconkey1062you mean astronomy? astrology are those horoscopes and sh*t
The distance between the comets, asteroids and even larger objects would be at least several if not more than ten A.U. One A.U. is 93,000,000 miles or 150,000,000 kilometers. Because of the very sparse distribution of bodies in the Oort cloud, and their jet black surfaces, we look right through it.
I can't help but wonder what it would be like to land on a mile wide object in the oort cloud and just sit there in the vastness of space. It would be a depressingly lonely place but also an extremely peaceful and quiet place.
@JJnS Farms 😂
Intriguing idea. I'd reckon that we'd not be able to spot any other Oort Cloud members, even when sitting on one of its objects. The Universe has that habit if repeatedly telling us "No, no. That's your daily life scale. The cosmos is qualitatively different. Forget what you might 'see'. Think more in terms of time, for ultimately that's what vastness really means - abyssal, imponderable periods of time"
@JJnS Farms no you'll find yourself a few days in yelling "why can't these damn alien kids stay off my lawn! And what's with their music?!"
No internet, no radio waves, no light once the electricity if the battery died. Just darkness lit by feint starlight until you died. Peaceful, indeed. And, in millions of years, you would never decompose.
JJnS Then falls asleep on the lawn chair only to wake up naked in an alien facility who are probing your behinds.
The Oort Cloud is so fascinating to me, I hope I live long enough to see astronomers learn more about it

It’s so wild to think about the scale of these absolute mega structures. The Oort Cloud in particular. When you put the scale of the universe into perspective, it tends to make you not stress as much about that next presentation. Stop stressing y’all. Enjoy it while we got it.
Oh Brett.
I was just stressing about a presentation. Thanks for the context!
@@jurassicmatt2796 don’t stress man!! You got this.
Structure?
I was thinking about the absolute astonishing scale of the universe and all the beautiful yet utterly chaotic things in it, and came to a deep realization that we all all infinitely small and insignificant, so I stopped stressing about it.

It’s insane how even if we imagine an “infinite” universe, the real life size of it is still bigger than we imagined.
Humans don't have the ability to imagine infinity, we just imagine something very big at most

The real mind-blowing thing is that our universe may be a size that is unlimited for us, it still is finite! So, we have all the advantages of an infinite universe without the physics problems it would have of it actually _were_ infinite! 😃 We will never be able to run out of more universe to explore. And if we did explore it all, doing so would take so long that when were done we would have forgotten what we had learned at the start, and have to start all over. 👏

This is also one of my favourites for night time relaxing, SEAs narration is second to none 🥇 my kids fall asleep while I learn about our beautiful universe ✨
I still remember seeing the Hale-Bopp fly by. I was like 4 years old, clear sky, waiting for the ice cream truck with my mom and she tells me to look up. Something I'll never forget.
I do too. Even though the previous approach to us was 4,200 years ago, and it will be 2,400 years in the future when Hale-Bopp comes back, it goes nowhere near the inner Oort or Hills Cloud today even though it likely was there long ago. Hale-Bopp was the most spectacular of the dozens of comets I observed.
I do too, but I was 30 at the time. It was spectacular with a tail that was 20 degree long and visible from my city, even downtown.
I remember Halley's comet when I was six looking up into the night sky with my mum. It was magnificent ☄️ I missed Hale Bopp though ☹️
18 months for light to leave our solar system...... incredible!
It really is ! 8 mins to earth , 5.5 hours to Pluto .... 18 months to leave the solar system ... my mind is fully blown ....
If the sun were to suddenly disappear, it would take 18 months for the light of the sun to actually fade out. It's light would still be there, but the actual sun would be lone gone. It's crazy, and that happens all the time, especially in the massive scale of the universe in millions and billions of light years. We are only just seeing the light of events that have already stopped thousands of years ago.
@@qwertydavid8070 The light would last a whole heck of a lot longer than 18 months
@@qwertydavid8070 do people often talk slowly at you?
@@qwertydavid8070 well no, it’s light would shine for basically forever, so long as you’re far enough away. Many of the stars we see in the sky are already dead, we see them as they were millions of years ago, and the same is true the other way around.

It's almost maddening when you begin to grasp how truly vast and extreme some of the distances mentioned in this video really are. Then you start to realize how mind numbingly insignificant they actually are when you compare those distances to the ones between just two stars, then you move to star clusters, then branches of the Milky-way, then between Us and the Andromeda galaxy. That's just two of the two TRILLION galaxies we know about. It really helps you realize that the bs we all go through in our lives really doesn't matter all that much lol
Now imagine, that same scale between you and a viral cell. If the universe was a particle of silt, our galaxy would be an atom.
We do matter because to us we matter. Meaning is such a rare thing in the universe which what makes us even more special and significant
@@eoin05 We are a parasite specie and our bodies can't survive to the extreme conditions of space, or technology it's not advanced to us live outside of this ball of rock and ocean. Our lifes in the cosmic scale don't matter at all not ever have purpose. Our lives matter here but it's a matter of time that we're gonna get ourselves extinct so yeah... Weare highly insignificant.
@@assgardiano that’s such a dead way to think of it bro u are a living thing aswell as all of us and from what we have observed that hasn’t happened anywhere else also things do matter as it matters to us maybe not on a cosmic scale but to us it matters and that’s what counts I don’t get why people think in such a negative manner just live bro
I don't even think our minds have the power to grasp the immensity of the universe
I wish these videos were on spotify, I would love to listen on long drives.
Damn I had not heard on any of the other channels the vastness of this cloud. Amazing reporting my man.
ive been wondering more about the Oort cloud lately... thank you for uploading this and explaining it comprehensively. SEA never fails to be exceptionally educational
I never tire of revisiting your channel. Thanks for producing these well done, carefully researched videos. There's something compelling and a bit unnerving about the scale and size of the Oort Cloud. I'm an old amateur back garden astronomer and enjoy imaging comets. The immense distances and orbital periods of these primordial objects are mind melting.
Even our vast solar system in its majestic grandeur has tons of building rubble dumped down the back of the garden behind the shed, next to the yellow bucket with a hole in it and the moss covered trampoline 😅
I’ve always been fascinated about the Oort Cloud and what lies beyond it ever since I found out about it at age 7... 11 years later and it’s still fascinating.
It’s there so that the Goau’ld do not find us again
@@mbukukanyau Last time I checked Dr. Jackson and General O’Neill took care of that 😉
I wonder if humanity will ever reach the level of technology required to explore our own Hills or Oort cloud, let alone that of other star systems. I have my doubts we'll get that far.
The David Attenborough of space did it again! Awesome video mate.
This is my favorite video of yours, I’ve watched it at least 5 times over this past year. Its so interesting and the music throughout is wonderful. A welcoming but mysterious tone, very nice platter for all the information. 🤘
Very touching ... very philosophical ... ... very close to the metaphysical ... ... in a way, very sad ... in another very blissful ...
"The Oort cloud is one of many fascinating things we don't see when we look up at the night sky and other stars. Each tiny speck of light from the sky abstracts the intricacy of its system from its planet and moons right out to its Oort cloud; the vast hidden shell that lies in the space between stars." What a poetic concluding paragraph
Your research and narration of these videos is unbelievable mate. Keep up the good work

You showing an exact scale of how large the Oort Cloud was in comparison to the rest of the solar system gave me an existential crisis.
25000 years to get beyond the solar system? It amazes me how far away everything is from each other. When you see a shot of a galaxy it looks like everything is lumped together so close. It is because there would be absolutely no way to view it at scale. Crazy
Plus most of us don't comprehend scales, and tend to think 9f the planets as being about the same distance apart, when the reality is that most planets in our Solar System are at least 50% further from the Sun as the next innermost planet, often more. one example is Saturn and Uranus, where Uranus is roughly twice as far from the Sun as Saturn. Neptune isn't quite as extreme, but is 10AU further out again (from Uranus), which is the same distance as Saturn is from the Sun. Get to Saturn and we are just a third of the way to Neptune, assuming a pile of things that include the shortest distance between the two planets, whereas the actual distance travelled by Voyager 2 was considerably greater.
Never stop making videos! I adore them because i'm really fascinated with space and there isn't as far as i know another channel like yours c:
There are a few more. David Butler is one. He hits just the right note with his measured pace. Anton Petrov for a daily science hit can’t be beat too. Event Horizon, Fermilab....all good for cosmology and things weirdly quantum.
"We'll never be able to understand another star system better than we understand our own" I mean... yeah. Even if we could go to other systems, I think ours would be more explored.
