ORIGINAL VIDEO: • How the Universe is Wa...
I wanted to try and understand more space and just the Universe overall and i did not EXPECT THIS!!
The scale of the universe is so mindbendingly vast, it's good to just sit back, put on a TH-cam video, and just chill out while you listen to how insignificant everyone and everything you know is in the grand scheme of everything
Yeah, more of this type of content would be awesome. The universe is a weird and wild place! I'd watch reactions to anything like this - black holes, pulsars, the detection of gravitational waves (that's another great one if you want your mind blown! It's amazing how accurately we can measure things.)
@@AbelShields reality is stranger than fiction. That statement wasn’t said for nothing. Not when we have entire planets made of diamonds and the likes
Vast isn't even the tip of the iceberg. At the end of the universe (which MUST have an end) what comes next. At the end of that (everything has an end) there must be something else. It's so mind boggling because infinity is conflicting in it's very nature. Everything has an end but infinity is infinite... 👀😶
@Bomma26 not saying I disagree with you bit you made me think of something, if the universe isn't infinite and yet always expanding, what can stop it from expanding?
And what we can see is just that... what we can actually manage to observe... what the hell is OUTSIDE what can be observed?
Don't be sad, or sorry, Don. The fact that in a universe this bewilderingly vast, we get to even be aware of it - and have our minds blown by the realization - is a precious gift.
Everything you learn, be it how the rasengan works or the scope of the universe in which a single human once dreamt up that fictional idea, exploration, discovery, and surprise are guarateed to be infinite.
To the curious mind, everyday is christmass morning, with as many new gifts to unpack as we can manage.
Enjoy it, mate.
Gives a headache sadly :(
💯 man. Well put.
Born too late to discover anything new on earth, born too early to discover anything new beyond it...
Born just in time to find dank memes
@@aadil1998 I live by that message
Born to say you gave up hoping and dreaming. And have no hopes to change that?
We are litterally discovering things every day man. Lol in every aspect. Pay attention. You’ll thank yourself.
Huh? This couldn't be further from the truth. In the cosmological timescale, we live in the golden age of discovery. And as far as I know, no Earth scientist claims that there isn't anything new to discover down here either, not by a long shot.
The observable universe is everything we can see through voyager 1, Hubble telescope etc, it’s estimated that the universe is probably bigger than we will ever conceive and the universe is expanding faster than the speed of light meaning we will never see past the observable universe
and the space between galaxies is gowing faster than light too (i think), so in x years from earth it will be imposible to see another galaxy.
@@agustindirisio2766 he said what your trying to say, except he got it right, yes the universe is expanding faster than light, yes this locks away anything over our cosmic horizon ever being seen, no it does not mean in x years nothing will be visible from earth because we are in a galactic cluster and that galactic cluster holds itself close because gravity is stronger than expansion, we wont watch our local cluster of galaxies disapear from sight, just the ones that arent part of our cluster those will disapear eventually, for our own galaxy clusters to disapear we have to wait for the era of neutron degeneration, but life cant exist then anyway so there will be no observers to see it.. neutron degeneration is when neutrons finally decay away as radiation then no atoms can be formed.. so it will be a universe full of nothing doing nothing never changing forever but still expanding the nothingness.. but dont worry, thats not for quadrillions of trillions of years from now and our sun only has 1.5 billion years left till it swallows earth and then shrinks to a cold tiny rock..
I thought they can't get images or sound in space so how did they get so many pictures
Of course you can take photos in space, where did you get that from?
@@AkohTech if you are earnest. most of the solar system can be photographed in the traditional sense. the most advanced camera's can take traditional pictures of most of our galaxy, albeit mere dots. then everything beyond is radio telescope photography, most of which is infra red. they are built to measure all forms of invisible light, also called radiation. this data is then reformed to make more understandable pictures. these will never be close to naked eye observations, but they are very exact to the collected data. the cosmic microwave background is a prime example of phenomena discovered this way
It’s so hard for our brains to comprehend how big the universe really is. The crazy part is that this is just an estimated size, the universe is probably even bigger, and this increases the probability for another earth like planet with life on it.
The “Universe” has theoretically infinite size. We will never reach the edge, ever. Even in 10^9^9^9^9^9^9^9 years. Its always expanding.
There has to a parallel planet or other beings out their… or another theory can’t remember who said it, maybe we are the very first species to exist…
Yeah what the person is showing is just what was observable. I heard we can't see our own universe.
It wouldn't even have to be earth-like. We're carbon-based life forms, but something else could be ammonia-based, etc. The chances of us truly being alone in the universe seem slim to none.
@@SoggyToast506 the barrier theory or something like that I think is what your referring to, which is that there's some incredibly tiny chance that a certain barrier to the formation of life will be surpassed, and that life on earth is the only place that has met the exact stringent conditions for which life can start, but I could bewrong haha just taking a guess at what you were thinking of. :) I personally believe that there is life out there just both the distance and difficulties in becoming intelligent life have kept us from finding the other life out there, mostly the distanced being the issue
I know it's not really your traditional content but, I'd personally love to see more videos like this. Also, to CLARIFY, the part they mentioned about only being able to detect a certain distance, they were talking about radiowaves, not what we can see.
(Recommendation: look into explanations for higher dimensions. It gives you a good feel for how much vaster even a single room could be).
There was both the mention of the observable stuff with the naked eye which was just a small square of our own galaxy.
to me Carl Sagan's words about every single person living on that tiny dot suspended in a sunbeam shows us how insignificant most of our squabbles are and how we would be so much better off working together as people.
But at the same time also how IMPORTANT we are in that insignificance. We might potentially be the very first intelligent life in the history of the universe so far.... perhaps we are not, but it's plausible.
"Oracle, are we alone in the universe?"
"Yes."
"So there's no other life out there?"
"There is. They're alone too."
- Written by James Miller from A Small Fiction ; there's also a nice comic of it from The Oatmeal
I feel it really captures the sad part you were talking about.
With how far each galaxies are and how fast the universe is expanding NO ONE WILL PROBABLY FIND ANY OTHER LIFE FORMS THAT IS LIKE US like i bet 10 dollars rn that there's already a few multiple other smart species that's at our level but we can't find them from how far they are.
Should do more similar stuff like this. Love watching just random reactions
What really bums me out is that even if intelligent life does exist somewhere out there, chances are really high that it exists so far away from us that we will never even detect, much less meet or talk to them.
That could be a good thing... given our history with meeting "foreign" civilizations.
@@LadyDoomsinger yeah true but it would be cool seeing other life forms as intelligent or even more intelligent than us
@@spiritual9574 Oh for sure, but I think as long as humans can't even get along with each other, meeting extraterrestrial life of any kind would be bad (for them or for us).
I'd rather we never find intelligent life, than find it, if we just mess it up.
I’d love to see you react to more videos like this about space, science and history.
Good Sir, please watch "history of the entire world, i guess" next. It is the perfect addition to this space video. You will 100% appreciate seeing it. Thank you and can't wait for you to react to it!
This reminds me of a memorable series of books I read as a teenager called The Ultimate Hitchhiker's Guide To The Galaxy where they would show someone everything in existence in an instant as a form of execution due to our brains not being able to comprehend it all and literally shutting off.
cool to see you reacting to stuff like this
Bro, Imagine Mario's face when he realized he's gonna have to travel across 2 trillon galaxies.
The flipside of the coin to your sadness is that you are actually alive in a time where not only we can observe our universe, but actually have that information shared online to educate us all.
Such a privilege. Be well ✌❤
Who else is certain that aliens are definitely real after watching this?
always known aliens existed
I definitely believe it after watching this
Life existing on other planets is almost certainly true, but intelligent life that is capable of traveling these unimaginably vast distances to visit us is far less certain. If we were visited by aliens, I would be far more exciting about the fact that a species has figured out how to cover those distances than I would the appearance of the aliens themselves.
@@susanmaggiora4800 i think intelligent life is out there
I think of it like a gambling slot machine. Every sun is a pull of the lever. Pull the lever a few billion times and you'll probably hit some jackpots. Having life evolve that is able to reckon the universe is the ultra-jackpot. With how many suns there are, there's bound to be many ultra-jackpots out there.
Hey, something I know a little about! (I'm just a guy who watches a lot of space videos, not a scientist or anything lol so correct me if Im wrong folks)
Our radio broadcast do not go beyond the yellow dot that was pointed out.
Were indeed going to collide with the Andromeda galaxy in the future. When galaxies collide, nothing actually 'collides' because stars and planets are still too far apart to do that . But many stars and plants and gas will be flung away from the center.
Supermassive blackholes are the gravitational center of most galaxies but they don't have enough gravitational pull to keep galaxies 'together', that's the job of the dark matter that surrounds galaxies (theoretically).
Telescopes like the recently launched JWST can see infrared galaxies up to a few hundred million years after the big bang (which is currently a mystery since we didn't know galaxies formed that early!). The part about how far we can see was specifically about the naked eye when we look up in the sky. That's why we know what the observable universe looks like. It's whats 'observable' with our various telescopes.
Light travels faster than anything, yeah. It's known as the max speed of causality because if you were to travel at light speed, time would stand still for everything except you. Going faster (which isn't possible) would break the laws of physics and you would end up probabaly traveling backward in time lol.
Is there life out there? Almost certainly. Will we ever get to know what it's like? Almost certainly not. It's bittersweet to think about :p
Even with these tools to help us visualize the scale of the universe, even while looking right at it, our brains still can't truly comprehend the scale.
With how big the universe is estimated to be, no one can ever convince Me aliens don't exist
People say it to calm themselves that’s what I believe
I've always said they almost definitely exist. Them making it here to earth is a completely different story.
Using pure statistics it's almost guaranteed that there is plenty of carbon based life out there and that doesn't even include the fact that there may be other forms of life that we can't even comprehend because we've never seen anything like it
next reaction, history of the entire world i guess?
Upvote
Really enjoyed the reaction! Wanted to help answer a couple things, not sure if others have or not already.
Even with how many stars exist inside our galaxy, and even more in the Andromeda galaxy, there is a very low chance that any stars would collide with one another when our galaxies merge because of the absolutely immense distance that is between stars. Some orbits of planets and stars could be effected by others which could certainly cause some major problems over long periods of time. It would make for one insane spectacle however if you were around to see it.
The way we know that these incredibly distant things like stars or galaxies exist is because we can see them with telescopes. Light waves that shoot through the universe become "stretched out" as they travel through space for significant amounts of time because of the expansion of space itself and those waves become way to large for our eyes to be able to see them. So to be able to see things very distant we use telescopes to capture the enormous waves and focus the waves down to a length that our eyes can see.
Whenever I need to center myself I put on some good headphones, lay outside, and stare up into the sky listening to something relaxing. Doing this you are looking into the eyes of countless other beings throughout time also looking up. We are all connected over time and space, transmitting our own thoughts into the ether.
Hi, dont know if anyone answered this yet the reason we can see observe a large part of the universe but our own broadcasts havent reached nearly as far is because the light from the things we have been observing has existed and been travelling towards us for vastly longer than humanity has been able to interact with the universe in a larger sense.
For your question about Mars' distance, it varies because of the shape our orbits around the sun are.
The orbits aren't exact circles, they're more oblate. Earth is pretty unique in that our orbit is much more consistent, leaving us constantly in the habitable distance from the sun.
Mars' orbit, to contrast, is both more oblate than ours (meaning it takes longer to get to the middle of a martian year), and also slightly off-centre, meaning it will sometimes be vastly closer to us than the last time it passed us by.
Loving the content bro, you should try and watch the movie interstellar if you haven't watched it already. It can get mindblowing at times.
When I was younger I thought about the vastness of space and I came up to a problem. What's on the outside of space? A wall. What's on the other side of the wall? More space. The idea of infinity blew my mind.
I love everything that had to do with space, if you could please do more reactions to such videos 🙏🏻
You should react to “History of the entire world I guess”
It’s a great video I’m sure you would enjoy 👍
10:04
The narrator said "Furthest Extent Of Humanity's RADIO BROADCAST SIGNALS" he didn't say that that little point in the Milky way was the furthest extent of what we can currently see.
The thing is, with the help of powerful telescopes and research, we can see the very edge of the universe (that's right, the very EDGE). Ever seen that oval picture of the universe with the blue and the green colors? Yeah that's the one, it's called the CMBR or the Cosmic Microwave Background Radiation. It's the very first light that was ever released into the universe!
The light you're seeing in that picture was emmited when the universe as we know it was just a few hundred thousand years old! Meaning that this light began it's journey to us before the Earth had even formed, heck before the Milky Way galaxy had even formed! It then traveled through space for over 13 and a half billion years, losing energy as it did so due to the expansion of the universe which slowly stretched it into low energy Microwave light by the time that it finally landed on our telescopes.
Now the place from which all of this cosmic radiation was released is formally called the "Surface Of Last Scattering" and not only is it the farthest thing in space that we have ever seen, it's the farthest thing that we CAN EVER SEE! It's the edge of the visible universe!
Take a look again at the picture(if u can, maybe look it up)
Now you might ask 'What am I looking at?'
You're looking at the moment that the hot early universe transitioned from an opaque plasma to a transparent gas.
You're looking at the light that was trapped within that primordial plasma
and set free at that moment.
You're looking at the AFTERGLOW OF THE BIG BANG!
in other words, you're looking at a baby picture of the universe.
(dis took so long to type so plz like)
We'll probably never leave our local group of stars. Space is too big.
This perspective helps people understand universal level characters in fiction. Imagine a single being capable of destroying or erasing everything you saw in that video... quickly and in real time. It goes to show just how powerful these type of characters are really meant to be... and we're not even getting into the multiversal level ones (especially in comics). That's a whole other level of power.
I wouldn't be sad, Don. One way I like to think about it, is no one in the future will know everything. It's easy to feel envious of the cool things some people will learn as humanity expands further out into the milky way, but there's a lot we get to experience they'll always be curious about as well.
Eventually there may be people zipping around with knowledge of their local intergalactic communities, but I doubt it will be much different for most people from how it is now. maybe there'll be some alien friends but there's not much else to learn out there other than what other entities might be up to in their particular corner of the local galactic cluster.
One day humanity may be spread across the stars. Every terraformed planet with its own history of struggle and overcoming alien environments. But each one will share a common history. They'll all share a common source. Us.
We get to exist at the start of it all. Life is quite convenient already compared to the past thanks to new technology and the journey to Mars will start in our lifetime. I think it will only accelerate as industry opens up to the solar system. We get to see how it all started before we spread out into an unknowable number of stories. I feel blessed to get to live in this era.
Definitely love your enthusiasm! I considered looking in to all of your questions because it is honestly incredible
most of the colorful pictures of galaxies and nebulas are mixtures of visible light, xray, and thermal imaging put together. so the actual image you see is usually much less exotic.
16:20 Makes me think of a scene in the movie Star Trek: First Contact
Lily Sloane: "I envy you, the world you're going to."
John Luke Picard: "I envy you, taking these first steps into a new frontier."
damn man i support how you made this video even though you wasnt sure if people gonna watch it, thats how you enjoy life!
Fun fact: When you look at the stars, you see the stars as they looked in the past. This is because light takes a very long time to travel from the distant stars to Earth, so when you look at stars you are basically looking into the past.
I'm an amateur astrophotographer, as far as I know when you look up at the stars you don't see the present, you see the past, that's why I don't think other civilizations will ever be found.
The funny thing is that we are technically seeing the universe in the past, so we don’t know if these astronomical bodies still exist that are millions and billions of light years away.
He said the furthest we could see with the naked eye was 99% within that yellow box. The Hubble telescope is literally a super powered light catcher, which is why we have been able to see and track the observable universe. The James Webb however can see further, and more clearly.
YESSS! I love science and was hoping you'd get around to this video because alot of reactors have done it and you didn't disappoint. If you like this id recommend 2 similar videos 1 is "VFX artist reveals the scale of atoms" and 2 is "VFX artist reveals the scale of the universe" they are both really mind-blowing and informative like this one.
More of this reactions! Very enjoyable. Its actually one of my most favourite video.
I one hundred percent agree with your conclusion, it makes me sad to not be able to see how far and what humans in the future will experience. however that's all the more reason to live in the present and try to enjoy what we have. Loved the video and seeing your reactions to how incredible what we already have found out is. stay happy!
What scares me is that if we managed to be able to travel faster than the speed of light, with the size of the universe, we could in fact be lost and can't find our way back home.
Don needs to watch some of those videos comparing the size of Earth to different planets and stars. Or maybe something like the Boötes Void when he had some concepts clear
I was 8 years old watching man in black 1 and at the last scene it zooms out from our planet to a point that the whole universe was a tiny air molecule on another planet that had creatures walking on it.. that gave me food for though for decades..
He quoted Carl Sagan in this video, I think you should watch his show "Cosmos", maybe even react to it. It's a really beautiful series about the Universe.
No, you're spot-on about Andromeda, and Saggitarius A*, the supermassive black hole in the Milky Way. Yes, the galaxies will collide in about four million years. It'll actually shred the Milky Way, as Andromeda is about ten times bigger. Oh, and yes, light in a vacuum is the fastest thing there is, but it's even weirder than that. Turns out that the speed of light is really the speed of cause and effect.
You should keep watching more videos like this, I enjoyed your real reaction and thoughts about the future no matter how depressing it can be because that's reality for us. Thank you!
As someone who loves everything related to space and universe since Im 5 years old, I've had plenty of time to think about it in a lot of different ways and every time I feel a little bad or uneasy in my life or when someone dies etc I just think about me on earth, then going back far far away and it's always a great feeling and will always make me happy and glad to even exist. The fact that something exist can be crazy when you look at it, and the fact that Im something that exist, but also able to see other things who exist, trying to understand them is so amazing that I couldnt care less for our present world's problems, my mind is always in space and nothing matters.
Also, you shouldnt feel sad to be born early and not being able to see what they'll find after us, because they will also feel the same way and wish they can see what people after them will find. We are lucky to have such informations and to have found out all this compared to our ancestors who also wished to see it. Dont be sad about your time, just live with it, because it doesnt matter when you live, you always want to see more.
I like this type of veideos! more Science and Space video please, I reccomend Black Holes next
Honestly the scale of the universe is just crazy to think about. Also, second!
You can't travel faster than light. But if you travel fast enough, you slow down your clock, so in theory you can go from one side of the universe to the other side in like 10-15y of ship time. But while you were traveling the universe would still pass the time at a normal rate. So if you travel 100 million light years away in 10 years, in 10 years you will see 100 million light years pass at superspeed. So by the time you get there, both at earth and at your destination 100 million light years would have passed.
7:54
Man just casually threw that in there😂
Just a note about the "Pale Blue Dot" photo: what look like beams of light in the _Voyager_ photo are actually the glare of the sun on the camera optics. Really, if it weren't for that glare, the rest of the image other than Earth should perhaps be much darker.
We can see all of this stuff because the light from the far away objects hits our detectors. The light takes time to get to the detector, so the further away it is the more back in time we see objects. Because the universe is expanding on the large scale, the light from very far away objects "stretches" and has a lower wavelength than what it was emitted at. So a star from a galaxy far away enough emitted a photon in the visible part of the spectrum, but we detect it in the infrared. This is why the James Webb telescope is engineered to detect in the infrared. The earliest galaxies are so far away that the space between us and those galaxies has stretched the light into the infrared wavelengths since it was emitted.
Damn Don, your closing thoughts are deep.
My biggest regret in life is that I wasn't born at the end of time, so I can't see how it all ends.
I enjoyed the video. Would love to see more space related reactions
Ooooooooo next you should watch an explanation of the 10 dimensions in our universe. If you’re watching scientific videos that have to do with the stuff in Rick and Morty, that’s a must. Because there are 10 dimensions of space total, not just the 3 that we know.
7:00 correction:
Yes there is a supermassive black hole at the centre of every galaxy but they have little to no influence on anything
Their mass only makes up 0.001% of their galaxy's mass
Its the gravitational effect of dark matter that keeps galaxies together
2:33, unlike the simplified models that are sometimes used, planets don't really orbit the sun in perfect circles. So depending upon where Mars and Earth are their rotations around the sun, the distances can be smaller or larger.
I agree. It’s so sad that we won’t know MORE! It’s also sad and scary that the universe is EXPANDING so stars and galaxies are moving away from us, so in a few million years from earth you won’t see anything, no stars, nothing, except for our own solar system.
You're reaction was absolute gold 🥇
I would love to see you react to the kardashev scale video from kurzgezagt
You seen to confuse what we can see with the naked eye, and what we can see with telescopes. What we can see with our naked eye is limited by a lot of things. Our atmosphere blocks some stuff, and so does the light from the sun and moon and our own cities. We can only see really bright stars, for example our closest neighbor star, proxima centauri, we can't even see with the naked eye because it's too small and dimm. Also, light when it travels long distances decays, until what's left is mainly infrared, which we can't see but telescopes can.
Telescopes on the other hand are out of the atmosphere and/or not influenced by the light pollution, can see a bigger spectrum of lights and colors, measure the background Radiation and all kinds of other stuff. Also, they are often bigger than our measly eyes and can see light that our eyes just can't. They're usually pointed at one area of space for prolonged amounts of time, which too helps. I'm sure you've experienced something similar when you've watched the stars: the longer you look, the more you see. Similar thing with telescopes, just instead for minutes it's for days!
It’s so crazy to think that there could be a planet just starting off like ours somewhere far away, with dinosaurs and all the animals we’ve seen
Another famous assumption in science due to the advancement in technology and medicine is that the first person to ever be immortal has already been born. Someone living now will be lucky enough to stay alive through scientific breakthroughs in human progression. They will benefit from all medical breakthroughs for disease and sickness. Because of the speed of our advancements, it's almost a guarantee that the first near-immortal human is already among us. I find that to be a crazy fun idea.
"in my lifetime I won't get to see everything else they discover" FINALLY someone said it. I've never wanted to be immortal but I've always wanted to know how the universe goes on beyond our lifetimes
Also the whole math section was just estimating how big the universe might actually be. It took into consideration how old the universe is and how fast the universe is expanding to calculate how big it might be now!
Even crazier part is that we don’t really know how big the universe is, we know how far we can measure (at least now), but there’s no great reason to believe it stops… ever.
The universe could be infinite and if it is, that’s a whole other level of mind blowing. Because if the universe is infinite, then you exist somewhere else, doing the same thing you are doing now, in exactly the same way. And you? You’re also infinite.
There’s no real reason to think that’s true or even remotely likely, but we can’t prove the universe isn’t infinite and if it is, everything happens infinitely.
Sextillion is such a huge number that our punny human minds can't even conceptualize it lol. This is so amazing. Ty for this video i enjoyed it
Telescopes are used for seeing the observable universe but space telescopes like the Hubble telescope have extended what is observable and more are planned for the future. Astronomy is amazing even though it makes us feel incredibly small.
Consider that we didn't know this until rather recently. Just a couple of hundred years ago we had no idea there were so many stars. You were at least born in a time where you could learn this.
The human brain just cannot fathom the size on the universe, these videos are the best way to put it into some form of scale.
When I die, I wanna become a star in space and just look at earth and see what they are doing and what they are discovering. I believe!!
You were correct about the center of the Milkyway being a black hole. It's called Sagittarius A and is blocked from view by the cosmic dust of the spiraling arms around us.
However, I don't know if every galaxy has a black hole, but I'd guess that it is usually the case. If anyone else knows, I'd like to find out.
To answer your question about why some things like Mars and Earth are not always at the same distance is because of their orbit around the sun. First, they are not perfect circles so that contributes to it but the most important factor is that Mars and the Earth don't orbit the sun at the same speed so sometimes Earth and Mars are on the same "side" of the sun, the distance between them is smaller than if they are on opposite sides.
2:28 because their orbits are not exactly circular, they're slightly egg shaped
Knowledge like this....changes a person, I used to be quite arrogant and full of myself, I can admit that....this stuff though....it tears through ego entirely...a life changing experience man....
"Wait, how can we see all this?"
The short of a very long answer is: When light left these objects, they were closer to Earth. The objects have since moved, but the light is still coming at us.
It's a big thing to also remember that Most of space pictures are in black and white and colorized by us so it's hard to say that's exactly how things look out there
Just wanted to add that the images are often colorized to help the viewer visualize the entire electromagnetic spectrum.
Some clarifying information:
1 AU (astronomical unit) is the average distance between the earth and sun or about 150,000,000km or 8.3 light minutes
1Ly (Light year) is equivalent to 9,461,000,000,000km (9.461 trillion kilometres)
Also if we invented light speed travel today, it’s unlikely we could escape our local cluster
the vergo super cluster are groups of galexies. The part we are in "local group" contains over 50, so yeah.
Hi, we see everything by analysing the background radiation.
To simplifie, after the big bang, a noise (vibration) remained zooming everywhere. If you interpreted that radiation, you can see this picture :)
Hope it helped
this video was so unexpected but i really like this kind of videos
did not expect this. nice vid!
VIRGOO GANNGGG!!! No wonder i was loving ur channel❤
What's really crazy about the universe is that we have already invented time travel through advanced telescopes.
Because the light takes so long to reach us from further parts of the universe what we can see in the furthest parts of the observable universe actually happened millions of years ago.
Like we are currently seeing stars and planets that already were destroyed a long time ago just because their light and shadows only just now reached us in the present
You know, i normally dont comment under videos, and I've been watching your content even before you started reacting to naruto, but the reaction to this video tops it all for me. I thoroughly enjoyed this video and your reaction don. Don't ever apologise for posting and reacting to content that you don't normally react to. This was amazing 🔥💙 keep it up!
The distance to Mars changes because it and the Earth are different distance from the sun and orbit at different speeds. So sometimes it's closer and sometimes it's further, depending on where they are relative to each other in their orbits. This is also why the different planets move around in the night sky from day to day. If you look up a graphic of the planetary orbits you'll see what I mean.
It's cool that you check out this video and posted it. This video is always a trip to revisit.
In To Scale: The Solar System they built a 7 mile across model solar system in the desert, and the planets are marbles you could carry in your pocket. Something about the physical model makes it more jarring for me.
To your question about if nebulae really look like that pic. Yes, and no. Those pics are multiple pics though different cameras that can pic up various wavelengths of light coming from them. If you could see every spectrum of light from visible, to uv, to microwave, to possibly gama rays. Then that's how space would look
Also, we can only see a tiny bit of our galaxy with the naked eye. But once we send satellites into space, they are able to pic up far more sources of light. Plus its not all that distorted since there is no atmosphere messing with the lights ability to be perceived. A real mind fuck, is that if the universe is truly infinite, meaning it had no end it fractals out without end, then its possible every single idea every single person on this planet has ever had. Regardless of how obscene or ridiculous. It exists out there somewhere. It would also mean there are an infinite amount of you and me doing everything we did today. To the t. Without any difference, as well as every other choice you could have ever made, and every potential outcome for your life playing out all at once. In the past, present and future. Playing out for infinity.
let’s say theoretically you had A pair of Scissors where each blade was 100 light years long, if you were to close those scissors you would immediately break the light barrier as theoretically the shears should close almost instantly spanning light years
10:08 You can see all of it because of light. Your naked eye can only see so much, but with a powerful telescope, you can essentially peer into the very outskirts of the universe. It is kind of like using a microscope. Bacteria are all around you, but your eyes alone do not possess the ability to detect them unless you zoom in to the point you can see them. Light also works in tandem with time. Everything you see is delayed, even the movement of your own arm by millionths of a microsecond because light needs to reach your eye to pick up what you have just seen.
The best example is if a alien civilization 65 million light-years away were able to zoom into Earth and see the surface, they wouldn't see us, they would see the last hurrah of the dinosaurs because it would take light 65 million years to reach them meaning they see Earth as it was 65 million years ago. The further back in the universe you look, the further you look back in time. Where the light ends is what the universe looked like when it was born. It is fun to think about huh?
9:51, they mentioned the farthest we can see with the naked eye. This would also extend to using a telescope as that only magnifies what we are looking at.
We know what is beyond what we can actually see by using infrared telescopes and x-rays of our skies. Light is within the visible spectrum that we can see, but many stars and interstellar objects radiate light that is not within the visible spectrum and radiates infrared, radio, microwaves, ultraviolet, x-ray, and gamma rays. Through several methods scientists use this entire spectrum to map out our observable universe
I've had a nerdy hobby for a year or so, wathing "the size of the universe" videos. Every time I watch one, this truth hits harder and deeper. But, anyway, it's feels good to know. Thumbs up for you👍
Mars can be different lengths away from earth because its orbit path around our sun isn't a perfect circle, it's more like a squashed oval
10:00 to answer your question, we can see this stuff because the light from those places has been traveling to us for billions of years. We're only looking into the past though but can take snapshots and calculate where things are.
this is honestly so humbling
There are scientists who devote their lives to exploring the depths of our universe. Using high tech equipment it is possible to see outside of the range we can reach
