Reacting to The Universe is Way Bigger Than You Think

hello so guys welcome back to another video and this is another random video reaction this isn't anything to do with history obviously this is a scientific type video but this was suggested a lot and i mean a lot and i'm still going to be doing all the other videos but the videos i see the most suggested i'm gonna look at and this is the one and the video is how how the universe is way bigger than you think this is gonna be one of those videos that sort of trips me out i have a feeling like i'm gonna be sort of like i don't know just sort of thinking about the world that we live in and then more than the world we live in this like space in general which is i mean i find it interesting but it's one of those things that does trip me out a bit so i mean we're gonna see what what's in this video but i hope you guys are going to enjoy and if there's any more videos that are related to this suggest them in the comments i'll be sure to do so in future but yeah thank you all for the support so far like so far i mean at the moment it's ridiculous and i just want to i just want to send my appreciation i guess i could say because again i'm not great at expressing emotion but trust me when i say this i can't believe what the hell is happening right now but it's incredible and hopefully it will continue and yeah i mean if you're new to the channel please if you like it would mean a lot and leave a like in the video as well but let's check this out and see how the universe is way bigger than i think this is a real life lore video made possible by squarespace make your next move with a beautiful website from squarespace this is funny you live here on this planet somewhere and everything that you've ever known is located right here but just how small exactly is earth when compared to the scale of the entire universe let's start by zooming out to where we can see our nearest cosmic neighbor the moon you may think that the moon is very close to earth since it dominates our night skies but in reality the moon isn't quite quite actually turn off this close to our planet it's actually about this far away 380 oh this is absolute 4 400 kilometers away from you right now on average you could fit 30 entire earth close to our planet it's actually about this far away 384 400 kilometers away from you right now on average you could fit 30 entire earths in between this distance and if you somehow were able to drive a car at a constant 100 kilometers per hour speed it would take you about 160 days to drive the entire distance despite this incredible distance however 12 humans have actually set foot here representing the furthest away that any individual human has ever been away from the earth and one of humanity's greatest achievements this is what the earth would look like from there if you were standing there with them and if you wanted to communicate with somebody back at home it would take a message about two and a half seconds to travel between you and them since that's how fast that sort of stuff trips me out like the fact you could even send a message to someone i mean you wouldn't be getting signal right surely see that's just i can't sort of get out get that out of my head imagine just being on the moon just texting just texting someone and then they receive it that just mind blows me but probably just it probably would be able to happen the speed of light can travel at this is a photographer on mars and that tiny dot that you see there is earth as seen from the martian surface on average mars is an incredible 225 million kilometers away from earth but that distance can be as high as 401 million kilometers that means that whenever humanity finally gets around to landing a human on the planet that person will be 986 times further away from earth than the astronauts who live in addition the time delay for sending a message from mars back to earth isn't just two and a half seconds it's actually more like 20 minutes each direction which would render instant communication in the event of an emergency impossible when we zoom out even further away we can find the voyager 1 space probe which is the furthest away man-made object from earth it is currently located 138 a use from the earth a u meaning astronomical unit which is the distance between the earth and the sun which means that voyager 1 is 138 times further away from us than the sun is at some point on its long voyage voyager 1 turned its camera around and took this photograph it may not look like much at first but in my opinion this is the greatest single photograph ever taken in all of human history this tiny pale blue dot is earth and i don't think that anybody has ever said something as amazing about this as carl sagan when he said if you look at it you see a dot that's here that's home that's us on it everyone you ever heard of every human being who ever lived lived out their lives the aggregate of all our joys and sufferings thousands of confident religions ideologies and economic doctrines every hunter and every forager every hero and coward every creator and destroyer of civilizations every king and every peasant every young couple in love every hopeful child every mother and every father every inventor and explorer every teacher of morals every corrupt politician every superstar every supreme leader every saint and sinner in the history of our species lived there on a moat of dust suspended in a sunbeam there has to be more out there don't know i don't even care multiple universes away or galaxies away there has to be another sort of civilization on a planet like this man i don't know it's just i don't know how they couldn't be because it's i mean we're gonna find out just how big it is now like we're finding out already but we're gonna find out how much bigger it is there just has to be man see these thoughts i'm getting in a real sort of like deep mindset about how things are he obviously got into it there and it's just when you really like think about it it's wild how everything that happens is on that man how how like what the [ __ ] voyager 1 is currently traveling at 17 kilometers every single second but even at that speed it won't break out of the reach of our solar system for another 30 000 years once we go beyond the solar system we arrive in our interstellar neighborhood here we since this is the neighborhood that you're in here so we're just like a little street on the neighborhood are you absolutely crazy bro look at this oh my god the light year unit of measurement which is the distance that light travels in a full earth year or about 9.461 trillion kilometers the star proxima centauri here is the closest other star to us other than our sun but it's still 4.24 light years away from us to put that into perspective if it was heading in the right direction it would still take voyager 1 over 70 000 years to reach it in other words if you drove your car at 100 kilometers an hour like in our previous example to the moon it would take over six times longer than the entire age of the universe is just to finally get there and it wouldn't even exist still when you arrived when we zoom out even further you can see the entire milky way galaxy inside of which earth is located right here this yellow dot is the furthest extent of humanity's radio broadcasts throughout history how are they able to find this out like i don't get how they're able to like scientists can find this stuff out it's [ __ ] bro this is i knew this could be a trippy video this is making me think differently possible aliens who live outside of this range are totally unaware of humanity's presence silence outside of this yellow dot as far as we are currently aware but the entire galaxy spans over 100 000 light years from end to end there are over 100 billion stars and over 100 billion planets inside of our galaxy but you have never seen the full glory of the galaxy at night because 99 of the stars that you can see with the naked eye are limited to this small tiny region right here but even this massive galaxy is nothing compared to the rest of what's out there zooming out even further and we arrive at the local group of galaxies stop it just stop this is it's just getting bigger it's just there's just no local galaxies what the [ __ ] galaxies that is about 10 million light years across but zooming out even further and we can see the virgo super cluster of which the local group here is just a tiny segment of there are at least 100 other groups of galaxies just like our own local group inside of here and the distance from one side to the other is a mind-numbing 110 million light years but even the massive virgo super cluster is nothing but a quiet and tiny are you are you done are you done i'm gonna go back because i want to properly listen but how like where do they get these names from how do they know this it doesn't compute in my brain how mad science is see i want to live forever just so i can see like what happens really goes within space man because i mean just to know all this stuff would be incredible like just to have the answers for everything like this would would be nuts 110 million light years but even the massive virgo supercluster is nothing but a quiet and tiny lobe of the great laniakea supercluster an enormous structure that is home to our galaxy as well as 100 000 other galaxies the distance from one side to the other is 520 million light years but from even there we can zoom out all the way to the entire observable universe and see that even the titanic laniakea super cluster is just a tiny this is the observable universe and it contains everything that we know of it is home to at least two trillion different and individual galaxies which together contain more stars than there are grains of sand on the entire earth the distance from earth to any side of the observable universe is 46.5 billion light years which means that the entire width is 93 billion light years isn't it just getting bigger as well what's perhaps even more interesting however is what actually lies beyond the observable universe keep in mind that the observable universe is all that we can currently see and it's entirely possible that the rest of the universe outside of it is vastly larger and more fantastic than we can possibly ever imagine when he says we can see it how does he how is he determining that is there technologies that can literally see this far because i don't really know how he sort of means that but if that's the case i don't i just don't i'm sorry i'm just repeating myself at this point i don't understand it the world is insane we simply don't know what else is out there because the light from these incredibly distant places has not yet had enough time in the universe's history to reach us yet back on earth and the light from some places may never reach us at all because some parts of space very far away from earth are expanding away from us faster than the speed of light that means that the light from these places will never in an infinite amount of time reach earth meaning that even if humanity is eternal and exists forever there will still be an unknown number of places in the universe that we will never know about or ever see so it is very likely that as unbelievably enormous as it seems the observable universe is just a tiny slice of what we can currently see of the entire universe according to the theory of cosmic inflation that was proposed by dr alan guth if it is assumed that cosmic inflation began at 10 to the negative 37th of a second after the big bang and with the assumption that the size of the universe before inflation began was equal to its age times the speed of light then this would seem to suggest that at the present day the entire universe is 150 sex tillion times larger than the observable universe that number for reference looks like this with this many zeros let this number sink in for just a moment this would be similar to you thinking that the entire observable universe everything that you could see was the size of a light bulb but then realizing that in reality the entire universe is larger than the former planet of pluto this is one of the craziest videos i've ever seen i can't i can't get over how absolutely mind-boggling this is man this is absolutely wild man this is absolutely wild imagine a light bulb in the center of pluto inside the light bulb were totally unaware that pluto existed outside of it and that's a similar situation to this we are all so unbelievably small but you shouldn't worry because all that means is that there is so much left out there for us to discover together this video was made possible by squarespace if you're wanting to create get your money man honestly get your money you deserve it for an absolutely astonishing video like this this was absolutely insane this has just opened my eyes so much more it's just crazy how how mad everything is now i understand why you suggested this this like this trips me out in the sense that i just we're tiny we're so small in comparison to everything and like how like he says like well when does they say the universe it would let me start again when they say the universe is expanding like when they say that do they just mean it's actually getting bigger or it's just so big they don't actually know like i don't i don't i just i want to know the answers to everything man this is how it comes when i look into sort of science and space i just want to be able to know everything it's not fair why can't i know everything man this is the video i fall back on when i'm feeling down about something helps me remind how makes helps remind me how irrelevant and insignificant my problems are honestly can't understand how someone could think of after watching this video and that we are the only beings in that whole entire universe and you're still scared to ask about your crush like how he broke this down so that a moderate moderately intelligent person can understand it feel tiny just imagine how bacteria feels after feeling this after watching this video the videos though bacteria is small but god damn it it's powerful man i'm looking at the virus right now it can cause damage mate so what you're telling me is star wars may be real [ __ ] sake but honestly hope you guys enjoyed this i really do appreciate you guys suggesting this to me and if there's anything out there that's anything similar to this this video i would love to see it i don't know how this is going to go down because this isn't like a historical type video so maybe people aren't going to enjoy it as much but hopefully you guys do go on to enjoy it and we can do more of this in the future but without further ado please like subscribe and peace
