Mom: "You're not the center of the universe!" Kid:"Well...according to this video..."

[@dimitrispapadakis2122]

you are still not in the center of the universe

[@InanisNihil]

@@dimitrispapadakis2122 actually we all are the center... 🤷‍♀️ im the center and i know it... im the center and YOU KNOW IT.. butt i also know ur the center... 😂

[@evilemperordude]

People are missing the point. Except for objects that are gravitationally bound, everything in the universe appears to be moving away from everything else meaning that space is expanding evenly everywhere. If this is the case, there can't be a center from which everything is expanding out from.

[@KarstenOkk]

the question wasn't "what is the center of the universe", it was "where was the big bang". those appear to be similar questions and would appear to have similar answers, but i think they don't. the way i see it, the first question has the answer of "nowhere". the second, "everywhere".

[@Groggle7141]

This doesn’t disprove the Big Bang Theory. Let me put it this way, whichever planet you are in our solar system, it will look like the other planets and the sun are orbiting your planet. But that doesn’t mean that nothing in the solar system is orbiting each other.

[@Narutogokuwizard101]

HOW TO DODGE A QUESTION IN ONE MINUTE

[@HDitzzDH]

He answered it? by explaining how certain things literally can not be the "centre"

[@Narutogokuwizard101]

***** Well that's not and all but he never stated where it was.Just stated how each area could be a center of th universe.Didnt really answer it

[@HDitzzDH]

Hououin Kyouma If one really wants the answer to "where did it happend" then I am sorry but no one knows.

[@Yal_Rathol]

+Hououin Kyouma space as we understand it didn't exist back then. the question is undefined. it's a bit like asking "when was purple?" sure, could sound logical, i'm asking what time was purple. but the question is undefined and means nothing.

[@Narutogokuwizard101]

Yal Rathol I feel like if we are able to somehow calculate or find feasible evidence of how old earth and the Big Bang is.Im sure those questions aren't beyond our reach.We just don't have the technology as of now.I'm still trying dying to figuring out what is the smallest thing in existence beyond a atom and beyond that etc.There has to be a source within reason.

[@metrih7]

I'm not special?! But my mom wouldn't lie to me right... RIGHT!!!

[@maxwellsequation4887]

She would not lie on basis of what she has been told........ The lie is centuries ago Lol

[@yasyasmarangoz3577]

You were too close minded to see the universe from different perspectives. This time, forn your mom's :)

[@Sirmenonottwo]

But where the fuck was the big bang god damnit.

[@JackKnapp2]

Eli Kelley Everywhere! The point is that to answer where an explosion happened, you need to find where everything is moving from. But no matter where you go, YOU seem like that point! So, the big bang happened everywhere.

[@Sirmenonottwo]

TheBigMack Jackable The better answer is that it is not known where the big bang happened in the universe. Saying the big bang happened everywhere is like saying the house fire started everywhere since in relation to the fire everything is on fire. This is wrong, detectives will be able to figure out that the fire started in the kitchen from the stove. The house did not all just combust at once. If the big bang happened everywhere then that mean there was no big bang essentially, the universe was just snapped into existence. No, the question that minute physics was supposed to answer was "where in all the space of the universe was the area in which all the space of the universe expanded from, i.e. where was the big bang?" It didn't do that, it just told us that everywhere is the center there fore nowhere is the center, which didn't answer the question assuming the was a big bang that started smaller than an atom and EXPANDED into the entire universe. Do you get the picture, minute physics did not answer the question.

[@joey3070]

The question is flawed. You have to understand that there was no before the big bang. And the Big Bang begun where space-time begun. You can't put a location on where space-time begun because space-time defines what a location is. Without the big bang, there would be no notion of where or when. Think of the universe like a giant sphere. The sphere grows larger as the universe expands. From any point on the sphere while it grows, every point around it grows in every direction opposite the point. This would make it the the "center" of the sphere. But the sphere started from it's actual physical center, rather than from a point on the sphere. So there is no center of the universe, but there is a point on the universe as a sphere where it began... but that center cannot be defined as a point on the sphere (where we exist). If I have conveyed my thoughts correctly, you will understand that there is no center of the universe, and the universe expands from it's center (which does not exist in space-time). To more easily digest the fact that there was no such thing as location before the Big Bang, think about it in relation to time. There was no time before the Big Bang because the Big Bang was the birth of time. The same goes with space. There was no "where" and there was no "location" before the Big Bang because the Big Bang was the birth of space and location. You can't put a location on the birth of location, because there is no such thing as location beforehand. The Big Bang technically did happen everywhere because, going back to the sphere, the sphere began when it was it's tiniest, when there was only one point that existed on all sides of the sphere. That point, the only point, would be where the universe began, which at the time would be everywhere. As the point expanded, more points existed, all of them being from the first point, all of which are the center of the universe everything around you is expanding like marker dots on a balloon, all of the dots are the center of the universe to itself, all of which are the epicenter of where matter began... so all points in the universe are where the Big Bang began because all points of the Universe existed as one when the Universe was born. So... The big bang happened everywhere.

[@laurainc]

+Joey Sofia that can't be right because the sphere has an edge the universe has no edge. the bing bang happened everywhere because it was at a point where the entire universe was condensed, but then that means space time didn't have a begining, like Henry said in the video before this there was no begining so that means that space-time is infinite, so is the universe, and, therefore the big bang happened everywhere to everywhere

[@joey3070]

kawaii Senpai By the sphere comparison, i meant the surface of the sphere is the universe. It has no end, but is not technically infinite. math.ucr.edu/home/baez/physics/Relativity/GR/centre.html for more information

[@mikzin630]

That didnt answer the question, sadly.

[@PeregrineX7]

The answer is that there was no beginning point, or at least not one we can ever find, no matter how advanced our technology becomes. When the Universe began it was infinitely small, so without any physical size, it is impossible to determine where it is in our (sort of) infinite universe.

[@ToadrixAce]

Peregrine how o u know it was infinitely small? maybe it was an atom across, then that atom is the where the universe began

[@paramethratnasakha3962]

aceXXofXXhearts because no space exhibits before big bang.

[@ToadrixAce]

Parameth Ratnasakha no, no space outside the big bang exists

[@paramethratnasakha3962]

same as inside, BEFORE the big bang. It's singularity. In fact, there is no matter before big bag as well, only pure energy exists.

[@Alex93435]

This video is obviously false, I mean, they don't have cats on the moon...

[@sermuns]

Alex93435 I know right!

[@dimitrispapadakis2122]

actually they do

[@rootabeta9015]

Someone has clearly never been to the secret lost pet city on the moon

[@justmehere_]

*puts on tin foil hat* that's what YOU think...

[@tHa1Rune]

You didn't actually explain anything here other than the point that everyone who thinks they're the centre of the universe is an idiot. What you should have said is that the universe is expanding like the skin of a balloon being blown up, so there is technically no centre.

[@tHa1Rune]

Because the most simple way to imagine the universe's expansion is to think of it drawn on the skin of a balloon. When you blow it up, everything will separate apart at an equal rate from each other, so there will be no centre, even perspective wise.

[@tHa1Rune]

Patrick Mahoney nice one literally reiterating everything I just said TWICE haha :P

[@SgtMickle]

This episode didn't tell me anything.

[@MWcrazyhorse]

Me neither. I want my money back!

[@Clymaxx]

It told you plenty. It's not his responsibility for you to understand it. Where was the Big Bang? The answer is that although logic might point us to a singular point and that point should be obvious, the truth is that it is not. It is relative to your perspective, literally your frame of reference. Meaning, the location is not determinate in a meaningful way. We would need to measure from outside the Universe, a proposition that may not even make sense.

[@SidheKnight]

Why does this awesome video have so much negative votes?

[@MikaMikaWhatever]

Creationists, damn Creationists. They read the title of the video. They just clicked on it obviously just to down-vote it. They didn't even bother to watch the video. Deist btw

[@chaincat33]

***** he did kinda in a roundabout way. he pretty much said "fuck if i know and theres no way anyone can know"

[@shkotayd9749]

***** He did answer it, but he didnt give the answer most wanted to see. Mind you it is a very difficult answer to understand in a normal common sense frame of mind, but the universe doesnt have to work by our perspective lol. Sadly that fact is enormously difficult for most to digest. at all.

[@Steam1901]

***** Shkotay D He really did not answer the question at all. What he said is that it did not start at Earth's location. There is kind of an answer to this question, it's long and very theoritical, and obviously no one can be sure, but that's not the answer at all.

[@shkotayd9749]

Steam1901 The point literally is everywhere though, and any one place can say it is the centre if it wants. It is an irrelevant thing. In order to ask where the point was when it first started to expand, it has to be in relation to something else, and there is no way of making such a comparison. But from the inside, the point really is everywhere.

[@jorgesantiagol]

So where was the big bang?

[@wolfpytlak2786]

everywhere/nowhere at the same time, so it doesn't matter were you go, you're always in "the center of the universe"

[@emmadewitt1139]

***** you can't pinpoint the exact location of the Big Bang because everything which exists expanded from it. The only way you could find the center is if you define the parameters of the universe or quantify what exists outside of the Universe. (The space that contains the Universe)

[@granbubba]

+Wolf Pytlak NOOOOO, youre in the center of the Observable universe.. not the universe itself.

[@melissab6060]

Obviously, from that video it's clear the big bang happened somewhere a little east of Albuquerque.

[@paulmahoney7619]

The answer is: that question is meaningless.

[@gburyhockey9]

no dude, the whole point is that there is no center of the universe. the big bang happens when all of the matter of the universe is reduced to a infinitesimal size, the where of that question is irrelevant because it is not a single point inside the universe, it is the universe itself reduced to that size. the universe expands not from that single explosion that happened way back when, it expands because all the planets and shit in the vacuum of space are moving away from everything around it. in short, space is expanding from every reference frame so then every reference frame appears to be the center of the universe

[@HenryKron]

How did this videos answer the title like wtf

[@colinkurtz8759]

+HgKron It was answered because he said that there isn't a definite point. It could have expanded from anywhere, it wouldn't change a thing. There is no center.

[@ComandanteJ]

Just run the expansion in reverse in your head, and you'll find that this vid answers the question exactly right.

[@lanunjawa]

Henry, I love your videos. Please make more and make them longer. Your videos are a way that is so much more interesting to learn Physics.

[@GrimReaper-bg2fg]

Hi, know this is after 8 years, but if you haven't seen it yet, Henry has a video called "A better way to picture atoms".

[@Tkb135]

He answered the question by denying its premise. He is basically saying the big bang did not happen in one location so we cant figure out "where" it happened.

[@Excalibur2]

I really love this channel, I learn so much in such a short time while staying entertained the whole time.

[@HeroEric98]

title should be "are we the center of the universe?"

[@GreenLightMe]

people want to know, where is the singularity in retrospect to the earth, in other words, if we could "rewind" the universe - in which way would the earth be pulled toward the singularity? The answer is we don't know but there was a singularity so if we could rewind, we would move in a DIRECTION toward the singularity and we'd even be able to determine where the singularity is because some matter would have to be closer to the singularity than us, if we got sucked back into the singularity before the andromeda galaxy than you can reasonably say our galaxy is closer than andromeda, which means there is a PLACE where it all happened.

[@Yal_Rathol]

yes, but due to the expansion, that "point" is probably several million light years across by now, and is a random point in the middle of the void from any perspective but a god's.

[@gburyhockey9]

think outside the box ... the singularity does not exist in a single coordinate inside space and time/spacetime, the singularity is the whole universe (i.e. everything) shrunk down to an infinitesimally small point of dense matter and energy. outside this singularity is nothingness (as far as we know at this point ... we would have to know what is inside a black hole to know what nothing is or something like that, idk) so relative to our position in spacetime, that information is irrelevant because our position and every other reference frame/position in spacetime would be INSIDE the singularity that was the big bang

[@jamilhneini1002]

GreenLightMe except if it's infinite

[@chanderule605]

It was everywhere If we would rewind the time, the opposite of what is happening right now (inflation) would happen We would be what everything cramps into, but only from our point of view

[@InanisNihil]

there is no "singularity" that term.. unfortunately is literally "GOD" as in science ACTUALLY DOES NOT KNOW THE ANSWER so there for a SINGULARITY... literally thats how and why and when that term is used.. so as a atheists and a huge fan of the scientific method.. i think this term and how its used is utter garbage and just reminds me.. even logical and reasonable people can still resort to silly religious like thinking.... "WE DONT KNOW.. WE DONT HAVE THE ANSWER... PHYSICALS BREAKS DOWN AND WE DO NOT HAVE THE TOOLS TO GO ANY FURTHER.. THEREFORE SINGULARITY.." BULLSHIT

[@TheRahulnk]

this is the 100th minute physics video ... Congrats Mr.Henry!!

[@TheDegario]

He did explain it. The Big Bang happened everywhere at once (see his previous video where he explains it should be called the 'Everywhere stretch').Look at it like a balloon: if you draw points on it and then blow it up. It would look like they are moving away from the center, while, if you take another point, you'd have the impression it all moves away from that certain point. Your frame of reference is everything.

[@bencrispe2497]

The center of the universe can only by everywhere if the universe is truly infinite. If it's not, we would need to somehow see the universe from the outside to determine where its center is.

[@IdentityDM]

Could we not ask where the center of the observable universe is?

[@auspolk]

IdentityDM The centre of the observable universe is earth. Because the observable universe is just that part of the universe that light has had enough time to travel to earth so we can see it.

[@htfkid2000]

auspolk that could be extended to say the center of the observable universe is you. to me, the center of the observable universe is me

[@tahalil5909]

Which is actually impossible to accomplish considering the fact that the Universe itself is enormous.

[@epicfaceguy]

the Universe doesn't have a center. but from our perspective we are the center of the universe

[@nitrodog96]

This it more "Where wasn't the Big Bang?" than "Where was the Big Bang?"

[@idaved4]

You know what imma try out that audible book, looks pretty cool

[@pomme1231]

Your last statement, amazing and priceless, thank you for making my day. Haha

[@xianlim57]

We know we're the center of our observable universe. :)

[@nesslig2025]

"where was the big bang?" "yes."

[@euducationator]

it's you.

[@kylea.1223]

***** Didn't you just watch the video?

[@papier2765]

U didn't answer your question

[@emoboybadboy12]

He did answer it by saying that from our point of View the earth was the center of the big bang, and this means every other point of view is the center of the big bang, "it's the universe's way to make us feel special" , so the Big Bang happened everywhere, that point where it started from was everywhere.

[@UnremarkableSteve]

awesome video! thanks :D

[@tomatensalat7420]

Wow, I actually wondered about this a few days ago. Thanks alot.

[@CrazyKiller1112]

I have an idea. What if the universe could be described as an sort of four dimensional sphere where one dimension is the time dimension and the other three are our common everyday x, y and z dimensions. This could be hard to explain so ill try to describe the same thing with an three dimensional (one time and two spatial dimensions) universe where an sentient being in it would observe the universe as an only two dimensional circle but an being from our universe standing outside their universe (however that would be possible) would see their universe as an slowly expanding universe where it would be an two dimensional plane wrapped around an center from where time began (and possibly where and when big bang was) thus making the center of origin nowhere on the two dimensional plane. one good metaphor would be a dotted balloon where the surface would be the universe and the dots would repesent galaxies (or galaxy clusters) and then inflating the balloon. the balloon would expand and the dots would separate and move apart but there is an center of the balloon as observed by any person seeing the balloon. but the center wouldnt be on the surface thus not being in the universe anymore due to that the balloon would expand away from the center of origin. The same thing could go for our four dimensional universe but its hard to use the balloon methaphor because our minds couldnt imagine an four dimensional sphere. So if this was correct then the place and origin of the big bang is not in our universe... Well not anymore atleast...

[@Laurence2000]

It could, but as we weak-minded humans (in one relative) can only comprehend three. According to string theory it could be 26...but then again, that's just a theory. It could be infinite...*Mind commences blowing up*

[@Narcissist86]

For starters, there ARE three spatial and one temporal dimensions, so if you want to invoke some sort of higher dimensional analogies, you'll need to add another dimension in. You're probably thinking of a sphere in FOUR spatial dimensions (and keeping one temporal dimension, of course). While it is difficult to picture a 3-sphere (the name for a sphere analogue in a one higher dimension than the sphere we know), its mathematical properties are well known. What we DO know is that we don't need to invoke higher dimensions in order to picture expansion. In fact, if what you said is true, then there should be measureable curvature in the 3 spatial dimensions that we know of - but the latest evidence suggests the curvature is either negative or zero, both of which is in conflict with a 3-sphere.

[@thomasnuckols]

So....This video didn't answer the question in the title....

[@assassin101c]

It may not be clear, but this implies that it was everywhere.

[@Zalamedas]

Thanks!

[@TheTineyTots]

this is soo informative, thanks a lot...the tiney tots...

[@shkotayd9749]

Well, Henry explained it right, but by reading the comments, no one was listening or they didnt understand :( I thought it was simple, but maybe he can do another.

[@qweezark]

After watching this three times I still feel he didn't actually answer the question. He gave a great detailed description, but no definitive answer. Occasionally you can read a comment here which brings up a theory to further add to the possible answer. However in all actuality we're still missing a few pieces of the puzzle to even call the Big Bang definitive. It's just widely accepted because it makes the most sense mathematically.

[@shkotayd9749]

qweezark Nope, he answered it. You just have to read a few more other descriptions of this questions. It boils down to "the big bang was everywhere and there is no centre, cause every place in the universe can be seen as the centre, but if you shift views, then everything is also expanding away from that new point. And so on, and so on". There is no centre it expanded from. The big bang is everything, and all matters placement in the universe is relative to change perspective the instant you view it from another spot. He said it all, just boiled down a lot more. He cant tell you there is a real, fixed centre, cause there isnt one. He said as much.

[@shkotayd9749]

qweezark Oh, and since the recent gravity waves finding, they have direct evidence for Guth and Lindes expansion of the universe, which in turn is itself direct evidence for the Big Bang. To be fair it will need a lot of confirmation to be taken as law, but the team did a LOT of work to rule out alternative causes as well. Sixty Symbols did a great review of the work, and pointed out this needs replication, but remarked that the BICEPS 2 team did a hell of a job in making sure their case was tight. Aside from actually being there for it, they have the certainty they are looking for in that matter.

[@qweezark]

I'm sorry... He may have said "There is no center", but does not imply that it is everywhere. Before it expanded it was compressed into a single point that physics as we know can't explain. Once we find proof that multiple "Big Bangs" exist, either in parallel or series, Then it'll be definitive.

[@shkotayd9749]

qweezark Physicists already have analogs for such an event known as "black holes". There is also no law in physics saying that there is a bottom limit that matter and energy can be compressd into. As many have said including Hawking "whatever isnt denied by the laws of physics happens". You are also talking about proof of the multiverse. Lets work on this one first before going onto other ones ;) As for this one, the gravity waves finding is about as dead on as you are going to get aside from actually being there the moment it happened. That is essentially direct proof. There are MASSIVE amounts of indirect proof demonstrating an expansion from a point. You also misunderstand the concept of the expanding universe. There IS no centre, unless you want to say it is everywhere. From our and other planets or galaxies points of view, any of us can say we are the centre. This isnt easy, but our common sense view of the universe is the wrong one. The physics view of the universe is the right one, as bizarre as it sounds. Listen to the video again a few more times and you may get it.

[@ComandanteJ]

3643 people did not get it.

[@Demintika]

43 people did not get it in the last 2 months.

[@ComandanteJ]

That's why so many people hates physics at school... if they cant even get this very simple concept, more complex stuff must seem like nonsense to them.

[@stacy4422]

but that is not the point! The point is on top of there head!

[@alecmartinez6569]

They get it. They are just religitards.

[@winson5159]

The title of this video is misleading. There is no "where" before the big bang started because there is no space and time to say "where".

[@Rewtem]

The idea of this video is to show that asking "where" it happened is a question that doesn't make sense if you want "where" to apply to a single place in space.

[@blazenetwork3749]

I actually liked how this video was so short and easy to understand.

[@jackolad1000]

So where did the Big Bang occur?

[@shkotayd9749]

Everywhere.

[@jackolad1000]

ok then, thanks for it and sorry Henry,I couldn't understand what you meant by "everywhere" :P

[@Yal_Rathol]

where was the big bang? yes. no, seriously. that's the answer. the answer is yes.

the point is that it didn't happen in any one place, it happened everywhere.

how many pages of paper do u use per show of minute physic's ?? o.O

[@spaceinvador1855]

if there was no space then the big bang didn't have a location

Good point.

[@TheAsem1992]

When is the next vid coming

[@jeepeedurocher]

A real MINUTE physics episode!!

[@jonathanbaxter4611]

So is everything expanding at the exact same rate? If not wouldn't we be able to find a center depending on how fast things are moving away and what direction? Like stuff could stretch with us and stretch away from us. If the center was to the left of us any thing to the left could be moving away, but slower than stuff on the right?

[@jasonk.]

plz..can make a video about the shape of time

[@zalyar]

Since space time itself started from a singularity from which it expanded to the current size, the ''big bang'' was everywhere.

[@aStealthyElfy]

Thanks for the free e-book, even though I don't have an e-reader

[@eddielatinokid]

This used to be my favorite channel too. Now he talks about biology. Good thing I'm in college now!

[@MultivectorAnalysis]

Judging by some of the confusion still displayed in many of the comments, I'd like to request another follow-up video clarifying the difference between the term "universe" and the locationally dependent term "observable universe." That video could address how spacetime expansion results in a radius beyond which recession velocities all become greater than the speed of light. This video deals nicely with the "no center" idea. What I'm recommending is one that deals with the concept of "no edge."

[@johnjohn9439]

can you do an episode on super-hydrophobic materials

[@marco.savini.128]

could you do a video about solar wind ?

[@raquelsanchez4129]

The 1st vid that's actually a minute

[@christophergallagher4370]

He did answer it - the center is everywhere. The big bang happened EVERYWHERE.

[@MultivectorAnalysis]

He did answer the question: no center, no edge! This video is like an addendum to the previous video, so if you're still confused about the answer, try watching both videos back to back.

[@drblueddad]

everything is being pushed away from eachother in every direction, because the fabric of space itself is the thing thats expanding. i guess you could say that the distances between us are expanding

[@kelakogreenaddict1888]

thanks, i get it now.

[@johnmaiennemangalili7692]

For all those still asking, technically, the whole universe was the "center of the big bang". The primordial "dot" that gave birth to the universe was the "center of the big bang", but since that "dot" was the entire universe itself just scaled down to an infinitesimally small space, the whole universe was the "center of the big bang".

[@Siam2233]

Which video. Please specify

[@atomicmrpelly]

At the start when you moved the stick man to different stars you forgot to "scale" the Earth!

[@mateja1003999]

Vsauce explained the "center" thing the same way,i didn't need to see it again from an another channel.

[@TheAfroman99]

I don't understand how the title of the video correlates to the actual video?

[@Yonason]

Happy 100 videos!

[@ImtheEntity]

Since the big bang was the creation of spacetime originating from a 1 dimensional singularity, "everywhere" is simply an expansion of the same point occurring at the same moment.

But Don, we do know the answer. At one time the entire universe was as close to a point as a non-point can get. Everywhere was at the center in one sense. And there is no center because all places were once as near the center as all others. The center is all around us as can be seen in the CMBR. Every direction we look we look back in time to the same center.

I think, the way they show how every point looks like a center, actually gives a hint on the answer. Its about particles, photons in particular ;)

Short but good idea

Thank you Henry for another excellent video. This video works well as a very helpful short addendum to the previous video "Science, Religion, and the Big Bang." I suggest clearly pointing this out in this video description. Perhaps that will cut down on some of the inevitable whining comments that come whenever you put out a shorter than usual video.

Oh now I get it

[@RobertPattersonDev]

This video tells us why every point inside the universe appears to be the center of the universe. It still leaves me wondering where was the origin was.

[@Rewtem]

It did in fact show that everywhere in the universe observes the same expansion and nowhere should be taken as the center. The expansion is happening from every point of view.

You mean the "everywhere stretch?"

One does not simply "Run out of physical phenomena to explain."

Hey Henry can you explain why electrons move around a nucleus that has a positive charge? why don't the protons and electrons just stick together to form an atom?

Look up the standard model of google in image search, then head to the website that hosts the first picture. It should be a detailed poster titled "Standard Model of Fundamental Particles and Interactions" I would've linked you to it directly, but KZbin doesn't allow that anymore.
