The Big Bang
 

This is a pretty good explanation of the Theory of Inflation (Big Bang), for us non-scientists.

Look around the room you're in, and imagine how all the stable, inert objects are the cold remnants of that super-hot, super-dense soup of particles--way too chaotic for atoms to even form until about four-hundred-thousand years later (an amount of time that it's difficult for us to even imagine--twice as long as humans have existed.)

I know that chick.

Never heard of him.

So that's proof of faster than light movement. Now we know it's possible.... just a matter of time until we're teleporting around willy nilly

My understanding is that space itself was expanding at that rate, not that something was traveling "through space"

that's why I said movement, not travel. it had to move if it covered a distance.... but if there was nothing to travel through, it couldnt have traveled. You might have to get outside the universe to move that quickly.

Does blowing up a balloon qualify as movement?

It moves right? But what is it moving in, if that's the analogy. If space expanded, what was displaced?

When I was a kid, my dad would ask us, "If the universe isn't infinite, what's at the end of it? If it's a big brick wall, what's on the other side?" Really good question, tbh. What did the early universe Inflate into? It's hard for us to imagine nothing.

Some of it moves not the part in/on your mouth so probably a bad analogy.
Maybe mento/coke in a balloon, everything's moving and that displaces air.
But the universe is displacing void, nothing.
We have trouble getting our head around infinite anything, no less nothing.
Well it has to end somewhere. Nope, forever and ever, amen. :mg:

We don't have the ability to observe something so large and so small at the same time. Space IS void. Or at least we thought so.

The empty space outside the universe is the same place my consciousness was before I was born.

Oh hey, there's some good jokes in that statement ...

… Wait a moment, I think I've got one …

… Yes, here it is:

No dear, the only empty space to contain your consciousness is right where it's always been...between your ears.

*takes a bow*

truth.


a thought, or collection of thoughts... a consciousness, requires no space, and yet they exist. If you think a lot of thoughts all at once, your head doesn't swell up or feel tight. if you empty your mind, it doesn't create vacuum.



The universe exists within the framework of a concept. We have no way of determining what that is comprised of, just the theoretical knowledge that it must exist in order to move out of the way of the universe as it expands. And will fall back in behind it when it eventually retracts.

I thought inflation was a theory just to explain how the universe is bigger that than light can travel over the age of the universe.

The idea that space itself can expand/that two things that aren't moving are actually getting farther apart is tricky because there is energy in "empty space" so inflation is basically suggesting that energy *can* be created which we all know isn't true. So there are some loose ends but it does explain some stuff.

Well, I heard the edge of the universe is an enveloping wormhole that funnels the universe back into the center of itself. That's why the universe is perpetually expanding and accelerating and will never retract. When all of the universe has been funneled back to its center, the wormhole will release it and there'll be another big bang.

Where do you people get those fairy tales about there being space outside the universe and the universe retracting?

there is energy in empty space, but that's not space. The concept is that the whole of the universe was contained in the singularity before the bang, and it's just dissipating. getting farther apart and less dense as it does. no energy being created or destroyed, just diluted. the existence and retraction of the emptiness beyond the border of that expansion is what bends my brain.

look man, we're all high and talking about deep stuff here. stop harshing my mellow.

Ran across this a few years ago:

Attachment 69266

There is, in fact, a hole in the universe.

It's all explained simply here:

That's gonna make the song a lot longer.:lol2:

I just thought of this when I read this post. Similar but different.

I recently read that the space is curved, e.g. parallel lines will eventually meet. And that e v e n t u a l l y if you followed the curve it would wrap back around. It turns out that we might not have to define an outer limit of space, it may be entirely self-contained and infinitely circular.
