I have heard theories that the universe has a sort of "filter" ( of alien origin) that is preventing humanity from contacting/ being contacted by alien life. Another theory is that the universe is simply so large that no intelligent civilization will ever be able to reach us, even if they were capable of light speed travel. Or perhaps, the distance prohibits intelligent life from ever noticing us.
@@Farscryer0 The problem with time is relativity and speed of light. The things we're seeing could very easily and almost certainly not exist anymore. Trillions of intelligent species could have gone through the whole evolution process and died before the first upright man.
It takes 8 minutes for the rays of the Sun to touch the surface of the earth........so anytime you look up to the Sun you are looking 8 minutes into the past (cool eh)
Expand that formula and you realize some of the stars you see have been dead for a long time, i.e. the supernova that was observed a couple years ago, that may have imploded a thousand years ago
It takes at least 100,000 years for light to travel from the core of our star to the surface, before it can then begin its journey to the Earth. So the sunlight you see every day is actually much much older.than you realize
Lol this reminded me of me and my friend. When it comes to stuff like this he trusts me to understand what they're saying. It's a really sweet comradeship :)
I believe that all world leaders should go into space at least once just to see it. As all astronauts who have been to space have expressed this profound experience that just shows how small and connected we all are. Perhaps then the world might be a better place.
Yep, it is even more humbling when you read the next paragraph of that quote: " The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot."
It seems impossible to me that we could be alone. When you are dealing with trillions of stars and planets the chances of something occurring only once are a near statistical impossibility.
@@doesnotexist305 Its like saying there is no fish in the ocean because we've looked inside a small man made pond. We're looking for life within a specific set of rules, meaning planets within the goldielock zone and carbon-based life
Yet we are certain that the universe is so fine tuned for life to exist, that it is already a statistical impossibility for us to exist by mere chance.
Andy B Obey Obey, you only think what you know based on what they tell you. You have no idea what is actually going on you just accept with blind faith because someone has a piece of paper saying you should trust them. Ignorance is bliss.
Troll Nation The universe is expanding. Intelligent people trained in the discipline can determine the rate of expansion based off the Doppler effect on light. Reverse the equation and you eventually come to a time when everything we observe was all in one place. About 13.7 billion years ago. And because light travels at a finite speed and the universe has an age, anything farther than 13.7 billion light years away we could never hope to see because the universe hasn’t existed long enough for light to travel that far.
Kenjuu you are making that assumption from a particular theory that you put faith in and that does not make it a fact it just makes it a possibility. There are plenty of other Scientists that disagree and have other plausable theories you just believe what your mind likes the sound of. There are plenty of theories of the exsistance of the universe from multiple as you say “intellegent” people. Again it all comes down to “Faith” and what you put yours in, who is the Authority...? Your mind or some particular Scientist that you think. The laws and physics of the close space we know of may not apply in other parts of space what to speak of different dimensions. For you to claim you know how this Universe was started and created is nothing but pure arrogance and ignorance. All you can do is wonder in reality, None of us know or will ever know those kind of answers you seek. There are plenty of plausable theories which put things like the big bang “Theory” to shame. The big bang Theory is just that its a theory not a fact yet you have already decided in your mind that its a proven fact when its not. Someone with your level of arrogance will struggle to truely learn and understand things when you think you already know all the answers. Debate would be futile when the purpose of it is to learn rather than to try and prove you are right. Have a good day sir.
His name is Rondo. His cousin on the right is named Frank. Frank has a sister named Ashley who used to be in their videos. Frank's dad, can't remember his name at the moment, is sometimes in their videos. Wish we could see some of Rondo's family too sometime.
I think its likely we are looking at an illusion. But trying to think what actually made all of this and how it actually started is truely crazy. For a 'big bang' to occur first there has to be a ball of substance to go 'bang'. So where did the original substance come from. Its a neverending mindf*k.
Carl Sagan's quote along with the pale blue dot image is easily one of the best quotes ever said, in my opinion. because it puts in words how unbelieveably small we are compared to everything else and the quote it self just puts into perspective just how tiny we all are in this universe.
@@rogerwilco1777 They aren't primarily trolls, I used to think so too until I saw a video of Joe Rogan debating Eddie Bravo and looked at the horde of astonishingly ignorant comments underneath. These people exist in numbers.
The vast majority are trolls dude, Eddie believes anything, He is in the 1%. The current trend of Flat Earth theory literally started on 4chan as a joke. It was a meme before meme's were a thing but somehow the stupid people heard about it and took it seriously.
"How do they know" Light that was moving away from you when it was made looks a little blue. Light that was moving towards you when it was made, looks a little red. They looked at stars with the hubble telescople. Measured the blue / red shift. did a SHIT TON of math. And the reults tell them how "far away" something is. We are a ball, we can look in every angle. So we take that "distance" and we can kind of make a 3d map, with us in the middle, of what the universe looks like. The way we get that info with the telescope is to point in in the same spot for a LONG time and put all the into 1 image.
They don't know. Mankind always thinks that we now understand. Until 20, 30 or 50 years from now. And we'll look back and say "We didn't really have that right"
TBH my primary takeaway from video's and realizations like this at first first a "wow." moment of amazement, and then secondly I start to think of how immensely difficult it would be to even begin to spread humanities reach to most of this. It's sort of frustrating to realize how difficult it would be just to explore and colonize even just small parts of the inner regions of our solar system. Seeing as how difficult it is to focus on space travel when we still have so many other more pressing problems among us that we have to spend most of our money and time on solving. We'd need some vastly more powerful communication and space travel technology just to begin to travel to mars and colonize it and the asteroid belt(which we should already be focusing much more effort on IMO, considering how mine able the asteroid belt would be). We've got 7.5 billion people on the planet right now, and it will not be long until - regardless of any climate change based argument - there will simply be too many people to humanely take care of. Faster than light communication and travel might not necessarily be possible, especially faster than light travel, even if it was possible to propel a space craft at that speed you would have to be able to map have a totally clear shot to get to wherever you were going . The only thing I can think of to solve the issue of sheer distance would be opening and stabilizing wormholes to bypass massive distances in space time but even in theoretical astrophysics, it would take a civilization capable of technology that could harness the power of a sun to even THEORETICALLY create something like that. Essentially using the star like a massive nuclear reactor, and how do you do that without developing tech made of metals that can interact with it without immediately melting? The only way reason we can safely harness the power produced by nuclear reactors is because they are contained and kept cooled, otherwise - disaster. I often think of what happened in science fiction series' like Judge Dredd when society got so big and technologically so advanced as to be able to do the jobs of most people; and think that it is fairly accurate. Minus the nuclear wars and irradiated wastelands, we're still going to face a massive issue of feeding people as urban environments continue to expand and will also continue to pop up in places that would otherwise be needed for farming. Building taller more massive apartment buildings like in Judge Dredd to house people is a simple solution, but even still the amount of homelessness and crime will skyrocket at a certain point due to there simply being too many people and not enough jobs for those people. Education in the traditional sense will also become increasingly difficult and that will continue feed the aforementioned problems. If people think there is already an issue with large class sizes, wait til we've got 25 or 30 or 40 billion people to work with. It'd be much better economically speaking to be able to move large numbers of people off of the planet to large space stations and colonies where people could live and work - mining companies would be the richest companies in human history depending on how far we are able to safely and reliably travel throughout our solar system and beyond. Would be nice to have some more man made islands like the ones China made as well to have more space for planting crops and housing people. It's something we should be thinking about solutions for now rather than later.
"How do they know that" has a simple answer. We can see it, hence the "observable universe". Just check out the Hubble Deep Field image for an example.
I think a lot of it is inference by doing calculations and such. For example we can't observe what our Galaxy looks like from the outside since we are in it. They go through a whole process of observing different parts and make a map on what it most likely looks like and that is how we get our models. Another example is that we don't usually directly observe other planets outside our solar system but instead we detect their presence when they pass in front of their star and then they can calculate how far away it is from the star and predict what the mass of the planet is and depending on the star, what the planet is like etc.
you live on earth, but you cant see the whole part of the earth and then there is stars at night, you dont live there, but you can see thousands of them with naked eye
"To say there is no life in the universe apart from us, is like taking a cup of water from the ocean and saying there is no life in the ocean" Neil Degrasse Tyson
@Исак Краизис he was using the cup as an analogy that the cup with water was earth and the ocean was the universe. Ofcourse there's going to be life in the cup of ocean water you dumbass. Shows how fucking dumb you are....
The Hubble Space Telescope opened up a lot of doors and allowed us to look billions of light years into space. look up "Hubble Deep Field" image. It shows Thousands of galaxies of all colors, shapes and sizes. Some amazing stuff.
Those are seriously some of the most marvelous pictures ever taken. I'm really looking forward to when the James Webb Telescope launches in a couple of years. Supposedly it's explicitly designed for deep field photography and will produce much better pictures than the Hubble Telescope.
"HOW DO THEY KNOW ALL THIS?!" --You guys should watch How the Universe Works, Season 1. Not react to it, just for fun on your own time. Seriously. Hell, I'll even send you the eps if you want. Even though I find science fascinating, I never did that well in classes, but I learned so much from only that 1st season. Like, did you know in about 3.75 bil yrs, our entire Milky Way galaxy is gonna crash head-on into Andromeda galaxy, BUT NONE of the stars and planets are gonna hit each other! Trust me guys, How the Universe Works - season 1. You WON'T regret it! Also, love your vids! (Esp the one with Hannibal and that Hot Pocket, hahaha. God, pls do more Eric Andre show ❤)
There are proponents of both who think their findings and research are legit ,it is not a either or question. "A little science estranges men from God, but much science leads them back to Him".
6:43 "How do they know all this?" Mapping out the 3D structure at a given time requires 3 coordinates. As we see things projected onto the sky, astronomers often use sky coordinates (Right Ascension and Declination --- analogous to latitude and longitude on the Earth) combined with a distance coordinate. For completeness sake, there are other ways to define this, e.g. a Cartesian coordinate system centered on some object (often times, displays of our "Local Group" of galaxies will be shown in such a system). Once you have chosen a reference system the sky coordinates are fairly straightforward to determine, by comparing the observed position of a source with existing sources on the reference frame. Historically the distance to galaxies has been difficult to determine. The calibration and development of the cosmic distance ladder has made this much simpler, particularly in combination with Hubble's Law. This law is an observational consequence of the Universe's expansion; that the farther away a galaxy is, the faster it is moving away from us. One can often measure the velocity of a galaxy using the Doppler shift of emission or absorption lines from known atoms (hydrogen is often used in systems with emission lines, and absorption line systems can use sodium or calcium features). Once you have the velocity of the galaxy, you can assume the velocity is due to the expansion of the Universe and use Hubble's Law to infer a distance and add that galaxy to your 3D model. It's worth noting that there is some error in the distance determination from Hubble's Law, due to the fact that galaxies don't live in isolation, but experience gravitational force from galaxies around them. This means they generally have some part of their velocity which is not associated with the Universe's expansion, but is instead due to the nearby galaxies. This "peculiar velocity" causes some uncertainty in the distance determination from Hubble's Law. However, this is only a significant uncertainty for nearby galaxies where the expansion velocity may be roughly the same as the peculiar velocity. For more distant galaxies, the peculiar velocity is small compared to the expansion velocity so the fractional uncertainty is low. There are other ways to determine the distance to galaxies, though Hubble's Law is the most widely used for mapping the 3D structure of the Universe. The other methods are important for calibrating the cosmic distance ladder and for some specialized studies.
want to know a space secret (as if you arent paranoid enough)? we know the speed of light, and how fast it moves.. bear with me.. so something 100lys out it would take 100yrs for the light from that object to hit us then we can see it right? now, look at some of the distances in the video, 100million, 5billion, etc etc.. so, kowing the average star lasts a few billion yrs. something that far away will still see even though it blew up a long time ago... so what im saying is, when we are looking at things that far out.. they might not be there anymore because you are looking back into time itself..
..was just pointing out that the things we see might not be there anymore or in could be in a completely different place.. so the star maps might not be very accurate at all...
This is an urban myth, and a very popular misconception. The truth is the naked eye can't see light from such distant stars, just ones in our neighborhood. It's a fun story, but it's completely false.
How did I miss this video in November?? So much fun watching this with you guys. Your observable success is only a small fraction of your potential success. Keep killin' it gentlemen.
There could be, but wed never know since the distances to travel are so damn big itd take magic or technology that breaks our understanding of science so it may as well be magic to travel those distances in any amount of reasonable (on a cosmic scale) time.
If you talk to most people who are studied/professors in this topic. A lot of them will that that its a statistical impossiblity that we're alone, but likely that we'll never meet an alien species.
It's easy to say that it's statistically improbable that we're alone because of the scale of the universe and abundance of matter we're made of in it. However, what are we really basing those statistics on? We don't have the necessary data to truthfully state that it's probable. As we yet don't know _how_ life forms. Which is a necessary piece of data to claim either. It feels unlikely we'er alone because of the former reasons, yes. But to really claim there's alien life would technically be wrong to do. Never let feelings about a subject interfere with science. That being said, I doubt we're alone. But again, that's only a feeling. I wouldn't claim that we're not.
I loved this since I was a kid. Always wanted to get into astronomy. Radio telescopes, measurements of radioactivity, all of this. Cool that you guys watched something on the subject
by far one of the most insightful and mind challenging documentaries... the universe is so vast and here we are on earth squabbling over little insignificant issues, especially economics.... when we can find a way for every single human being to have economic stability and focus our attention on exploring and learning more of the universe we live in....
No, it's just called being skeptical. What proof are they or anybody supposed to have again? What's your reason for specifically believing in it? It's ok to not know you know. It doesn't mean you're denying it to accept you don't know something. (same with god) Was you there to see them get in the rocket and watch it take off? Did you observe their journey through a telescope all the way to the moon? I know footage can be pretty convincing. But it doesn't matter how convincing footage is, (it can be completely legit, and i'm willing to believe it is. it makes no difference to me anyway) but it's still not solid proof. You think such footage couldn't possibly be forged up? Have you not watched many sci-fi movies? But i bet even if cameras didn't exist before rockets, and it was just told of over the radio, there'd still be many people who just openly believe without need of personally seeing any actual evidence. CNN still has an audience after all. lol Obviously it's something people want to believe in and support. I mean, that's how many kickstarter scams work even. lol
Great choice of video and reaction. It's good for the soul to marvel at the vastness of the universe. What's also incredible is that whilst looking out into the into the universe and having your mind blown by the sheer size. If you go back the way other way and look into atomic world and quantum physics, it's mind blowing how small an atom is eg. a pin head has many millions! And things get really crazy at the quantum level... eg. a particle can be in 2 places in the same time. You fellas should check out 'Dr quantum double slit experiment' for another mind blowing video! Much love from New Zealand!
I can't believe you guys don't already know about this. It has even been said there are over 400 billion stars in our galaxy not just over 100 billion as this said. You can't convince me there is not more intelligent life out there.
I took astronomy in college and the entire time I was 🤯🤯🤯🤯. It's mind blowing!!!! You should watch the cosmos narrated by neil degrasse tyson. I think it's on Netflix and Hulu.
Space is kinda like a wave pool. The galaxies ride along in addition to doing their own motions, like debris flowing in a river. Since it appears that space is expanding, it is essentially adding distance between objects and energy. This means that at a certain point, even lightspeed isn't fast enough to keep up. It's cool but a little scary to think that we won't be able to see anything farther than a certain point.
this was the first video ive seen where you guys actually opened your eyes wide lmao.. that shit be mad crazy to really think about! shit leaves me speechless everytime
“How do they know that? How CAN they know that?” Well. The telescope was created some time around 1600. And ever since humankind evolved the ability to, we have been looking to the stars. Some of them, they took notes along the way. We’ve been doing it for millennia, as a species. This is quite evident, in how many ancient ( prehistoric ) human-built monuments are designed to coordinate with the stars above our heads. Once you look a little closer ( telescopes ) you start to see how big it really is As long as you take accurate notes. TL/DR: Science.
Frank's eyes just look big because Rondo's look so small, lol. It would be like seeing my Johnson and your Johnson side by side. Mine's not actually that massive in reality.
I see you! Y'all branching out beyond reacting to comedy clips. Keep em coming it's great to watch different things with you i seen basically everything reacted to on this channel but it's like watching it for the first time for some reason when I watch with you. Probably because your reactions feel very sincere and genuine 🤙
The truth about the infinite size of the universe gets us nowhere except coiled up in a bottle of thoughts that we are ultimately insignificant in every action that we take and every second that we breathe.
You can fit every planet in our solar system in between the distance of the Earth and the Moon and still have over 3K miles to spare. Edit: Another cool reaction video from you both!
And this video is why I believe that there are millions of other planets out there with life. All it takes are the right conditions, and the universe is bigger than a human can ever imagine.
Any time I feel self important, I think of that infinite universe.... brings my feet back on the ground as it pertains to the significance of my existence in the grand scheme of things. Don't need a magic book filled with unbelievable characters and false promises to keep me humble! Peace . :)
Guys great videos. U got a new subscriber. Very friendly dudes and great choices for the comedy. This video blew my mind. So it was cool to see u guys watch it too
Now imagine how small fundamental quantum elements and their interactive forces are! You guys should react to a current video on machine learning or AI assisted design.
The dimensions going smaller are insane. I always thought the observable universe was hard to grasp. I'm not religious but whoever or whatever is responsible for this has a talent
Ya know.... when I watch those videos I feel all my problems sorta just disappear. Because I realize my problems don’t compare to the size of the universe. Kind of a relief actually.
They know it because we can see it. The light from those galaxies has already travelled and arrived here, and we see it with hubble's deep space telescope. Granted most of the galaxies we do see are far older now, than the light that travelled here shows us
