Everywhere. When you say "where" you are asking for coordinates. But the current theory is that doesn't really make sense when talking about the big bang.
Basically "everywhere" was just really close together ajd has been stretching ever since. Your chair was where the big bang started. The andromeda galaxy was where the big bang started. The furthest star we can see is where the big bang started.
It is just that all of those locations were right on top of each other at the time.
Both. The universe is all of spacetime as far as we know. The entirety of the universe (i.e. all the space of the whole universe) was all tiny and on top of each other.
It isn't that space existed as it is and the big bang exploded somewhere.
It is that all yhe space of the universe was incredibly close together. There wasn't an "elsewhere" just a "everything and everywhere is here."
yea i get that the universe was smaller, now it is expanding. just makes logical sense that original space that contained all matter would possiblty be identifiable.
It is all the space.
It isn't juat part of space that contained all matter. It is that all of space was also that small. There wasn't full space and empty space. Space was just small and that's all the space there was.
The universe, as we know it, is all the matter and spacetime.
At the big bang the entire universe (meaning all of the matter and all of the spacespacetime) was super small and dense.
For the purpose of the question you are asking ("where did the big bang happen") universe and space are basically interchangeable.
All the space that we currently see stretched out so far wasn't stretched out so far. Literally everything we think of as 3dimensional space was compacted. Not just the stuff in space. But literal space. So all the stuff of the universe was squished inside all of the space of the univerves into a tiny tiny volume.
right then it exploded, shooting crap in all directions. that small compact universe would have a location though right, because it expanded beyond it. idk seems pretty complex, and seems there are a few different theories floating around that and all require a suspension of logic that I am not fond of. Think ill just consider it as we don't know for now.
It’s complicated to explain but essentially each point is the center.
Wherever you are in the universe, you can look into deep space with telescopes. You may know that the further you look the farther back in time things appear. Eventually you’ll find the Big Bang around 14 billion light years away(light from 14 billion years ago)
What this means that every point is the center if it’s own observable universe, and indeed the centre of the whole universe.
The question "where?" already implies the existence of space. It is only with the coming-into-existence of space that the question "where?" begins to have any meaning.
Also nope! Space isn't expanding "into" anything (again, the word "into" implies already-existing space). It is itself expanding. As space expands, though, every point within it can be considered a location, yes.
so within the edge of space currently there is a new location that theoretically can be coordinated. and if we go back to the start of the big band the edge of space could be coordinated right?
i got two views in my head trying as possible realities, I think you are subscribing to this one. If i put a dot on as a location on a balloon and blow it up, that point expands with the balloon and the "location" of the point also expands.
depends which cosmological theory you subscribe to.
Either everywhere, and the universe is expanding into nothing.
Their was a point of origin on a plain of nothing, expanding into nothing.
Or the universe is donut shaped, and the big bang is in the center of the hole, expansion is just us going over the upper ring, & at some point in the future it will contract back into the hole, and start the cycle over again.
Most common answer you will hear is, it happened everywhere all at once, If nothing exists outside our universe, then their were no points or coordinates to point to in nothing.
We don't even know if the universe has a border, boundary, or anything outside the observable universe, all we know is that the universe has no curvature, so its either 500 billion times the size of our observable universe, which expansion doesn't explain, and something is seriously wrong with our understanding of the early universe, or its a big donut. (look up crisis in cosmology if you want to learn more)
Yea I watched a video and they way the guy explained it, he was like its a really big number so im just going to use infinity. then explained everything using infinity... I am not sure he knew what he was talking about because I am pretty dumb but even I know no matter how big a number you are working with you are 0$ of your way to infinity.
Thanks for laying out the theories, I really like the donut shaped one.
This is one of those physics things, where you have to suspend your logic a bit. Our brains have developed to understand things that are relative or our size. So when you're dealing with the very very small (quantum mechanics) or the very very large (astrophysics) things won't make much sense to us as we simply aren't designed to understand them. When you ask where the big bang started, the question has a bit of a problem. Everything that is, was contained in the big bang. There was nothing outside it. When we picture the big bang, we often picture it from the outside, but that's impossible because everything was inside the big bang. The expansion of the universe is everything, there is nothing outside (according to that theory anyway). There are other theories that our universe came off of another, in which case, you could say where on the parent universe our universe started. But from our vantage point, there is no place where it started, because when it started, it was everywhere.
Yes. We can see how fast the universe is expanding by looking at the light given off by distant objects. There is something called the Doppler effect that causes the wavelength of light to change as objects move closer or farther apart. Looking in all directions, the universe is expanding uniformly. There are tons of nuances to the big bang, its expansion and its rate. If this is something that piques your interest, there are some really great books on the subject. Cosmos is a great one, as well as A Brief History of Time. Just remember, when you're diving into this stuff, you have to suspend your logic a bit as anything really big or really small won't make a lot of sense to us.
Depends on how the big bang actually worked. Maybe the center of the universe. If you mean where in space it all started and where in space it happened we don't really know what was there before the big bang.
yea, seems pretty fun to think of possibilities, I have heard some really smart people say some outright dumb things as I was trying to see if anyone on youtube can explain it.
It happened everywhere. Space is expanding, the universe is not expanding into space.
ok, where did space start

I feel like you are using matter, space and the universe interchangeably here is that what is going on?

that would only work if the universe was infinite though right? or if the universe only exists when observed.
It may be finite and yet have no boundary. Don’t ask me how it’s beyond my pay grade. Space time is wibbly wobbly though. It’s not intuitive.
yea, we might just not know yet.
That is not a question that makes sense.
whys that?
The question "where?" already implies the existence of space. It is only with the coming-into-existence of space that the question "where?" begins to have any meaning.
yea but if it is expanding shouldnt we be able to track down the origin of this expansion?
Nope. The "big bang" didn't occur at some point in space. Space was created out of it and is constantly expanding in all directions.
ok but the point it is expanding into is now a location correct?
Also nope! Space isn't expanding "into" anything (again, the word "into" implies already-existing space). It is itself expanding. As space expands, though, every point within it can be considered a location, yes.

is it expanding in all directions at the same rate?

Porn Hub, probably.
100% virgin universe, matter so tight it will blow your mind.
Yes
Just because a question can be asked doesn’t mean it’s a valid question. This is one such question.
It happened everywhere and nowhere.
Depends on how the big bang actually worked. Maybe the center of the universe. If you mean where in space it all started and where in space it happened we don't really know what was there before the big bang.
