Where does the universe end?

[DampCat]

yes

you flippin' liar. you didn't need this thread to think that. you already think they rule our planet secretly!

 

[Gackt]

The Universe doesn't even exist.

 

[Dblaze]

Don't know but according to my son it revolves around him

 

[V4NT0M]

But where does the flat universe end then?

Idk, a few billion miles in each direction, if you go off the edge you just fall off.

The Universe doesn't even exist.

Yes it does, I keep all my stuff there.

It ends at the beginning.

This universe is just one big bubble. I reckon there is the bubble that is this universe, then a lot of radiation and where there is space, probably some more universe bubbles. The cause for the big bang and everything to exist is too random to be a singular entity, and too unmanaged to be a deliberate setup.

Of course we all know the above is a pile of tosh and we are really on one big giant "particle" compared to the species that are bigger than our universe. you know our universe is just the equivelant of a particle to us.

Oh god, not this discussion again

Anyway the big question for me is not where the universe ends, but what is after it.

I know but I was giving a short smile answer

 

[V4NT0M]

I think the more important question is: If you split the universe in half would it still be one universe or two?

 

[ThundyCat]

but there simply can not be planet after planet after planet etc etc etc. Surely.

Why not?

Why not?

Because in the eyes of some, it just isn't logical.

It's not overly unreasonable - I find it difficult to comprehend that something goes on forever and ever, just like existence not having a starting point.

 

[lemonkettaz]

I find it hard to imagine that at a certain point anything has become so sparse that nothing exists....

what is the nothing that is there? how can it be nothing if something can enter it's space....

 

[Conscript]

It's all explained here.

Hmmm, interesting point

The observable universe is around 90billion light years in diameter so thats the end I guess.

Bits past that are moving away from us faster than light speeds and are outside our horizon.

What? so after 90million light years, things move faster than the speed of light?

 

[MajorMaccas]

no, but if something that far away is moving away from us at close to the speed of light, then that instantly multiplies how many years it shall take the light emitted from it to reach us.
