expanding into a void. yes exactly how the big bang was created

the universe isn't expanding, it's just that space is increasing

Why does space have to expand into something?

Because God. Leave me alone.

It isn't expanding into anything, it's just expanding.

Outside the 'edge' (if such a physical boundary exists) of our Universe, there is no matter, no energy, no space, no time.

there is no space outside the Universe....actually, there is NOTHING outside the Universe.

Isn't nothing, something?

how do u know whats outside the universe?

The matter, space and time and all that shit started from something that something created.

Was all that stuff just floating in that nothingness or falling?

And if it was "floating" Then it must have been held by some sort of gravitational force right?

Its not expanding into anything, space ITSELF is expanding.

There's nothing everyday and familiar that it's analogous to.

I could ask you the same thing, but with you spelled as you and an uppercase h.

>>3591719

No, Prof. Hegel. It isn't. It is not the case that there exists anything outside the Universe.

>>3591722

because the Universe is everything that exists.... that is kind of what the word means, you know?

>>3591749
no, but I have no evidence that god doesn't exist either
this makes more sense to me than so called dark matter, dark energy, space expanding, ect, ect.

>>3591749
Actually, there is evidence that the speed of light has changed through time

>>3591759

Where?

The Universe is a sphere, if you keep walking you'll eventually go all the way around

Not expanding into anything. Space itself is expanding (at least relative to our current size and everything we use to measure space).
