I don’t believe in actual infinity or that a complete infinite universe is possible, also there can’t be nothing because nothing is nothing and it doesn’t exist so maybe the only answer is that it is like a sphere with no edges?
What are your thoughts?

I think space time is finite. Outside of the universe there is niether space nor time.

So what’s there outside of the universe? If there is something wouldn’t it be part of the universe too?
I don’t think there’s anything outside of the universe…

I don’t know if the Universe is infinite?
But I’m pretty sure there are other worlds, other life forms besides us humans.

I’m a big fan of bubble theory. That the universe is kind of a bubble, and that there are other universes/bubbles in the big nothing that holds it all

“Nothing” can’t hold anything, nor can it be big something that doesn’t exist.
It’s so vast it might as well be infinite based on how far humans can investigate

Isn’t the universe expanding. So it is moving to where it wasn’t before?
Idk if that expanding theory is correct.

That doesn’t seem to be what the theory implies:
The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist "outside" it. Technically, neither space nor objects in space move. Instead it is the metric governing the size and geometry of spacetime itself that changes in scale. Although light and objects wi

Thanks for sharing, I don’t fully understand that, do you?
About the scale and space time geometry.

Me neither, my knowledge of physics is very basic.

My father once told me we do t know where the center is; everywhere we look, it appears that ‘We’ are the center, but that just cannot be true. ‘All the stars are uniform this is.
A lot of people are into this topic, you’re lucky because you are discovering a passion and can enjoy a book on it al, maybe.

An actually infinite universe, not expanding but already fully infinite.

I don’t know much about astro physics so my answer is “i don’t know”

And you believe such a possibility is logically impossible or merely humanly impossible to grasp?

Possible maybe in mathematics but not in reality.

It’s a weird thought that there comes a point at the edge of a sphere, where there is nothing.
Yea that’s an interesting question that I never thought of.
How can there be nothing though. If we are looking at nothing how is that possible.
Doesn’t that mean the universe would be infinite.
But maybe its just beyond our understanding what infinite is like in reality. Like @NotSeksoEmpirico said.
