They don't really know because there is no way to reach it. You would have to greatly exceed the speed of light, I suppose. First time I stumped Google grin2

From the Carmeli equations, I view the fabric of space as bounded with the fabric of space-time moving at a space-time-velocity.


Reading is fundamental; understanding is not a given ability.

The size of our universe is otherwise known as the Hubble volume (size of observable universe) and based on how far light can travel since the big bang.

Very likely much more outside the Hubble volume that we will never see including possibly an infinite number of universes including virtually exact duplicates of our own.

Other theories suggest that for every black hole that exists there is an additional universe with possible different physical laws. Our universe could be the direct result of a super large ancient black hole that originally formed and grew to super galactic dimensions in another universe.

Other theories like string theory suggests limited number of other universes in the additional dimensions suggested by string theory.

Outer space never ends. It goes on and on and on without there ever being an end.

Try to wrap your head around that. crazy

We can't define or explain the expanding universe/outer space with our current limited knowledge of the physical sciences. Theories are just that.

I believe the accepted size is about 46 billion light years. We can't see beyond it and the universe for us is actually shrinking as everything moves further away from us. Think of it as being a point on a loaf of bread that you bake. As it bakes any point expands further away from another point.

Lots of theories out there, but there's a few generally accepted ones. The outlandish ones have no proof.

The eventual end of the universe seems to be the heat death and the actual end of time as there will not even be any energy left at that stage to even measure time. One of the last things to endure would be black holes as they slowly shrink over time due to Hawking radiation.

Thermodynamically, it still has to have expanded to the point of zero temperature.

The OP is asking what's outside that expanding barrier...

Not well acquainted with modern cosmology, astrophysics, etc.?

Or with the meaning of the word "theory" in science?

Big bang is really a joke, but mostly accepted by the scientific community, that alone should tell you what they really know.

My question is where did all these atoms/molecules come from in the first place that actually made planets/stars/galaxies? What did that matter originate from? Where exactly is space located? What exactly is space and how did all that form?

It more or less percolated out of the initial event. There's been a lot of work done on this in recent decades.

Depends what you mean by "where", "space", and "located". wink
