How the Universe is Way Bigger Than You Think REACTION!! | OFFICE BLOKES REACT!! 

Now you can see why people sometimes spend their entire lives calculating and cataloguing this stuff. There's just too much out there.

carl sagan's pale blue dot speech makes me cry every single time. as soon as that picture was on screen there were tears in my eyes.

Another interesting fact is that you're actually moving about 2 million miles per hour through space right now.

I love that we’re so insignificant, takes the pressure off

We are all connected. To each other, biologically. To the earth, chemically. To the rest of the universe, atomically. We are stardust.

“With all that space why do they still build studio apartments?”😂😂😂

Laniakea Supercluster - Laniakea is Hawaiian and it means “Immeasurable Heaven”

There's a line from Captain Kirk in Star Trek: Beyond that I think is pretty relevant to this video: "The farther out we go, the more I find myself wondering what it is we're trying to accomplish. If the universe is truly endless, then are we not striving for something forever out of reach?"

Have you guys reacted to the video "History of the Entire World, I guess?" its great!

Everyone on Earth should watch this video. Every issue in the news seems so petty when you realize how meaningless it all really is. This video should be the cure to racism, the cure to war, the cure to hate, the cure to politics, etc etc. It's all pointless on the grand scale of things. I love knowing how small we are. Makes all the hate in our world meaningless.

It would be very unlikely for life to not exist somewhere else in this HUGE universe.

NASA has explained that the uneven lunar landscape causes shadows to appear to be dropped in different directions from certain angles. The show Mythbusters also debunked the "two way" shadows nonsense.

That picture that Voyager 1 took truly is the greatest photo as the narrator mentioned. Damn.

14:43 nope. The observable universe is the (light bulb) while the (Pluto) is the entire universe.

The coolest thing I learned in astronomy was say you are looking at a star that is 10 light years away, you are seeing what it looked like 10 light years in the past, as that is how long it took the light to reach your telescope. Everything we see is what it used to look like, and not actually what it looks like at this second.

With how vast the universe is, there's definitely another intelligent life form, somewhere... but, the problem is... they are so far away from us, that the moment we saw each other, we might already cease to exist.

Real astronomer here and i am surprised the video did not tap this down to layman's terms so folks can comprehend just how fast the speed of light really is. At 186,000 mps (miles per SECOND) that is 7 times around the Earth in one second. Think about maintaining that speed for over 4 years to the closest Sun, Alpha Centauri. Human's have no metal or engine anywhere close to the technology. Little trivia for those of you that were Lost in Space tv show fans, Alpha Centauri was mentioned in the show and really is the closest Sun to planet Earth. Its actually a triple star system but i digress.

You guys were particularly funny during this one. Carry on! (I may mean virtually nothing to the universe, but I mean A LOT to me!)

You actually can prove whether or not they're making things up. String theory, for example, is not actually a theory. It's an unproven hypothesis. And yes, they had to invent 11 dimensions in order to make it work, but those dimensions are, like string theory, only shown in mathematics, not proven. They are ideas of how the universe could work, not models of how we believe it works.

My guy couldn’t go 12 seconds into the video before abruptly stopping it. 😂 👍🏼 caught me off guard bloody good one mate!

"i love the fact that we're fuckin' nothing" gets me everytime

I lost it when Dave starting talking about fleas 😂. Great stuff gents!

That "shadows are both ways" bit got me almost questioning everything I know but it took me a little bit to realise that the shadows aren't both ways, its the shadow from the landing pod haha

@officeblokesreact gosh years later you’re still rocking.

Hello, Office Blokes. I really appreciate that you have recorded an astronomy/physics video. I hope you loved it. I just had to tell you. That was your best video yet besides maybe the hardest NFL hits.

What's fun is comparing all the different reactions to this video and seeing who's reactions are the smartest lol.

To my knowledge the Cosmic radio background is the reason why we know alot about the fractions of a second after the big bang.

*_Imagine what other types of creatures of organisms are living in the other galaxies!?_*

Great video, guys! The three of you never fail to entertain. Cheers from Hawaii. 🍻

History of the entire world, I guess? - great watch!!

The human brain can't even comprehend the size of our own galaxy, it's just so massive we can't imagine it. We can pretend and try but it's impossible. And the whole universe? Impossible. I love to think about what other species is looking up at the stars wondering what else is out there, we are connected not by each other's knowledge of each other's existence but the possibility. I love space so much, I will never not be amazed.

Yo was homie in the middle trying to do the math on his fingers when they were talking about the Theory of Cosmic inflation lmao

when he said "that's why we need 5g" i went STRAIGHT to the comments

This is deep.......

I'm of the mind that our incredible insignificance amplifies the importance of looking out for one another. This tiny rock, and our collection of people, are all we have, and unless we discover some form of faster-than-light travel, they always will be.

“That’s why we need 5G” LMAO I CANT

I do find it comforting that we're so small. I've always found it hilarious that old time philosophers and astronomers thought the universe and everything revolved around the Earth and humanity 😂😂.

We are the universe experiencing itself.

Astronomy student here. There are theories of the final fate of the universe, which include "The Big Crunch" where everything will collapse back on itself en.wikipedia.org/wiki/Ultimate_fate_of_the_universe

Glad that the video mentioned my super cluster! (The name lol)

Instead of being depressed at the fact that we're small we should be fascinated by the fact that the world is big

We’re all the result of a stellar queef from sometime long ago.

I dont think being small makes us irrelevant, its the other way around. Because everything we have, and are, is so close it should be treasured that much more. Nothing else that we can see or detect has what he have and we are unique. Whether there is other life out there it's not human life nor any other species on our planet.

The numbers they talk about are just mind blowing.

Sun and lighting guys just think about it before being all how’s that possible can’t be. I love when people just jump to a conclusion on the spot

You misheard one bit. The Lightbulb/Pluto comparison was representing what we can see of the universe (the lightbulb) vs what the science predicts the actual size of the universe would be (Pluto).

I made a good friend who's favorite question to ask people was if they believed in aliens. My answer. "Of course. Even if your definition of aliens was life on other planets...be they intelligent, or just animals, or organisms with just a few cells....the odds are yes, there is life somewhere out there. the odds of a planet in the butter zone of a star in the whole universe is too great for there not to be."

They didn’t say everything you’ve ever known they said EVERYONE you’ve ever known

Of course they are making it up ! The main point is: no one has proven them wrong, that is why it is called a theorie :) Liked it !

So I can explain how we know/discovered all of this! And I'll do it in "Physics for Poets" style. So, first a question: Why do you want new phones with cameras that have more megapixels? Same with telescopes - we all want better pictures! So every since the first telescope was invented 500ish years ago, people wanted something better. Galileo: "Look! Jupiter has 4 little moons around it!" Cassini: "Whoa! Saturn has this huge honking ring around it!" Later Generations: "Cool! But it's all fuzzy … let's try inventing better telescopes." Basic human stuff: the more we saw, the more we wanted to see it _better._ The next ingredient is Geometry. The Ancient Babylonians, 4000 years ago, had figured out (1) the Earth is a sphere; (2) the Earth's radius [i.e. how big the Earth is]; (3) that the moon was 30 Earths away, or "60 times the radius of the Earth. All with Geometry. And math: we actually have clay tablets from Ancient Babylon with some kid's math-homework on it! [The Ancient Babylonians were obsessed with the number 60. Religious significance, apparently.] We can use that same Geometry to figure out how large all of the planets' orbits are and how far away they are. And as we made better and better telescopes, we could take that same Geometry and apply it to those better images. And with that, we were now measuring how far away the stars are. The Sun is a pretty important thing, we can all agree. So, no surprise, people wanna know how the damn thing works! And how far away it is. But, see, once you know that, you can then compute how bright the Sun looks on Mars. And around Jupiter. And at Saturn. That same math and physics also lets us compute how bright each star looks close up. Well, once we figured out that the stars were just other suns. So, once we knew how the Sun works, we knew how _all stars_ work. And we were already measuring how far away the nearby ones were. And we can measure how bright they look _here_ on Earth. That's all you need to compute how bright each star is close up. And once you know how a star works, and how bright it is, guess what? You can calculate _how big the star is!_ Okay, so: the Geometry part, which we need to measure how far away a star is, only really works out about 6000-8000 light-years, if I remember correctly. I won't bore you with the math behind why unless you really wanna know. So how do we know about all that stuff *millions* of light-years away?!?!? Enter "The Ladder of Standard Candles" Remember how we all wanted to know how the Sun worked? And how that then told us how the stars work? Well, after watching lots of stars to _make sure we had our models right_, we started seeing behaviors that the Sun don't do. And some stars seemed to act in the same "different-from-everyone-else" ways. Back to the whiteboard - time to enhance the models about stars! Okay, great. We know more and more about stars … different kinds of stars even … the more and more we look out there in space with our telescopes, which we always want to keep making better. Throwing the Hubble Space Telescope into, well, space helps us see more clearly. There are other space-telescopes, but they don't look at the sky using visible light. They look at infra-red, microwaves, x-rays, gamma-rays - which are actually all different "colors" of light that we can't see. But that's an explanation for another time. Turns out certain kinds of stars are always the same brightness. Like, exactly the same. So say you have one of this kind of star "nearby" … near enough that we can still use the Geometry part of computing how far away it is _and how bright it is close up._ But Remember: this kind of star always has the same brightness as the others! So once you know how bright one of them is close up, you know how bright they all are. Take actual brightness. Take "how-bright-does-it-look-to-us". You can compute the distance to _any_ of this kind of star, no matter how far away, no Geometry problems anymore! It's a "Standard Candle" glowing in the dark. And if we see one of this kind of star in another galaxy, when we compute how _far away it is,_ we also know how _far away the galaxy_ that it's in is. We now have a way to figure out the distance to nearby galaxies. But, again, this technique can only get us so far. To figure out larger distances, we need more knowledge. More physics, more chemistry, more astronomy. And wouldn't you know, in the past 50-70 years, we've been figuring all that out. There's a certain kind of supernova that's always the same brightness. This is the next "Standard Candle". So we used the "certain-kind-of-star" technique to measure how far away a nearby galaxy with one of these supernovas is. And Here We Go Again: "How far away it is" + "how bright does it look from Earth" gives us "How bright was this exploding star to anyone close enough to get fried by it?" This kind of supernova is always an identical explosion, so look for others in galaxies even further away and measure how bright the bang looks from Earth. We know how bright it is close up. We can measure the distance to it. And this new "Standard Candle" in the dark is frickin' exploding star! Kinda hard to miss. Really easy to still see from very, very, VERY FAR away. But this still doesn't get us to the very outer edges of The Observable Universe. For that, we use the expansion of the universe [discovered by Edwin Hubble at the start of last century] and the Cosmic Background Radiation [discovered, accurately measured, and modeled at the end of last century]. Okay, so I'm being _really handwavy_ here. Can't be helped. Just know that we use this information _combined with all of the science, measurements from telescopes of all kinds, and techniques for computing distances_ to get us to the furthest reaches of the Observable Universe. So it's not just one person figuring this out. It's 4000 years of humans, generation after generation, learning, discovering, observing, computing, _and using what the previous generations learned_ to figure out the new stuff _that the next generation_ will build upon.

"No I know it from outer space" LMAO

7:24 And that's my mates, what i call a HONEST ANSWER. btw, me neither. lol

7:34 its actually not dramatized, when the said speech is given by Carl Sagan himself, a pioneer in Cosmo Science Research and Theories, who has dedicated their life to such studies.

I cant wait until I'm one of those theoretical physicist guys so that I can come up with a new hypothesis on how the universe works lol, thatll be fun to stretch that creativity

I'm happy that people still react to this kind of videos

I love how in one of the demos he said, “very not to scale.”

Watch Carl Sagan's full speech. The point he was making wasn't that we are insignificant which is kinda obvious. His point was that the Earth and our existence is incredibly fragile. Thats why we should take more care of each other and the natural world because it's the only one we got.

The best outlook on how small we r here on earth and even our whole galaxy is the end of Men In Black when the alien picks up our galaxy and it's a marble and then throws it n a bag with a bunch more galaxys! Pretty cool way to look at it!

I think the mythbusters did a show about the shadows on the moon landing and how they wern't parallel so they recreated it with a scale model of the LEM and 1 light source and found it to likely be caused by the uneven topography of the moon. Also up there light doesnt react the same as on earth another example is how dark the shadows up there are compared to here

Imagine... every grain of sand on Earth as a Sun with its own solar system of planets... Crazy

2:53 You can Say that You are not looking at the sun or the moon, You are looking that the ligth that reaches the earth, so yeah, still in the earth

As an amateur astronomer its awesome, in that word's literal sense how totally insignificant we are...and yet...its very quiet out there...we may indeed be one of those first civilizations in the galaxy...we may end up being what in sci-fi they describe as "the firstborn" or "the elders" or whatever you choose to call them...we will plant new life out among the stars...its very humbling how little we are...and yet all the potential we have...we may be insignificant as individuals...but not as a civilization...and in that all of us play a part...remember your Shakespeare...life is but a walking shadow...

If you look closer you can see all the moon shadows are facing the same direction. The space shuttle is behind and to the left of the camera man, the sun is behind them casting shadows.

5:15 5G is gonna give us back the curvature of the Earth 😂 that killed me

A college roommate and I used to get high and watch "The Universe" from Discovery channel. I didn't think I was a woooooaaaaahhhhh kinda stoner but I guess I was.

This stuff is so fascinating and mind blowing.

"That is proper poptard" lol..im gonna use that from now on when the weed is good =P

the flag moves because he moves it. sure theres no wind. but things will still move around if you touch it and move it around. :-D

Props to the person who counted every grain of sand here on earth....If your reading this you're a real trooper....

3:45 Where are there shadows in two directions? And if there were, the craft has lights too for sure...

it's the jokes you guys crack that makes me want to watch these videos with you rather than on my own.

Actually a grain of sand within the light bulb within Pluto size comparison would represent the size of the Laniakea Supercluster. Earth would be a tiny fraction of the size of a quark, the fundamental particle that makes up hadrons like protons and neutrons, so way tinier and more insignificant and precious than a grain of sand.

"Don't take a drink every time I say something stupid" 4:26 in and the 3 of you already got me drunk FFS!

The moon is not a source of light. It just reflexes it

flags do actually move in space or in vacuum

They are like the only people that i would understand if wouldnt know universe is huge *Couch* *couch* Asmongold

Lmao your guys reactions are always a great laugh. Keep it up 😂😂😂

that stupid looking number at the end would have been the first bit of time in existence hence it being so low lol

They should have played Kansas " Dust In The Wind " while commentating this video.

@ the 2:03 mark, every viewer got hammered

I now don't think we are alone.

The lightbulb part meant that if the *observable universe* was the size of a lightbulb, the whole universe would be the size of pluto.

I feel you guys are most logical and make sense in a discussion as per physics and space, than any other reaction channel I've came accross so far😅🔥

The fact that maybe some aliens watching earth from a microscope like the humans watching the atom🤯🤯🤯🤯💀💀💀💀

they had lights on the lunar module

American Vet: You guys are great. Half the time you are all bloody pants & pissing about, half the time you are all bloody brilliant!!! Live to Survive!

Small doesn't mean insignificant. Small is also relative. The complexity of the Universe is dwarfed by the human brain, which has far fewer neurons than there are stars, but those neurons interact with each other differently every immeasurably small passing moment. If we looked at the Universe from that perspective, then we are quite special.

i spilled my water when he said 5g .

The thing that scares me if that when we did what will we be doing for the next trillions of years. Will be be reborn on another galaxy? Be reborn on earth with a new body? Be some kind of spirit that does nothing? Like that’s the scary part.

This gives me fucking anxiety 😂😂

I was not stoned enough for this

Even if some scientists or even everyday people like those guys who make fantasy webnovels are just "making stuff up" it is still Meaningful because Existence is reasonable, you need some basis of thought to "make stuff up" and even if your office workers cant disprove it because you cant understand it , there will be someone who can and will prove or disprove stuff , thus we as a civilization make progress.

What causes a shadow to go two ways is 1. the light source and 2. a very powerful and large reflective surface. It was argued that the reflective surface of the Lunar Lander was in the right position to reflect the sun's light back onto the flag from the other angle.

I was just about to suggest this video to you guys. :) You got yourself a subscriber

Oh. There’s definitely aliens out there now. That’s to many possibilities to not have aliens.

And this is how I got an anxiety attack

Its funny because if you go the other way, and talk about our cells and atoms. We are effectively their observable universe.

What the video doesnt explain is how big an AU is. Its 147.3 million KM or 92.9 million miles. Yeah its a great video.

the light reflecting from earth+ the ssun + light from the craft

Yes. We, as individual humans, mean nothing. What it SHOULD clarify is that EVERY last human is on the same team, and we need to get over the stupid ish that separates us. The ONLY point of humanity is to advance it, and that takes everyone working toward common goals. Funny thing about Voyager: The first humans to leave our solar system, and the ship they travel on, are a LONG time from existing. However, they will certainly leave our solar system before Voyager, and could even swing by and scoop it up lol.
