Is the universe spatially infinite

[Meeksauce]

I say yes, all signs point to yes. It is the most simple and elegant solution, as explaining a finite universe is much more difficult. Scientific discoveries will only further point to this over time.

 

For example, the discovery of the universe being curved to such a degree that it is basically flat, which easily lends to a spatially infinite universe (like a minecraft superflat infinite world. If you have a curved universe you will end up in the same spot if you travel long enough in a straight line.)

 

I propose that when the big bang happened the universe became infinite immediately and what we know of as the expansion of space is actually just a "render" that can go faster than light.

What is space? 

If space is a featureless, structureless thing, then it is not a thing at all.

The only way to know about space is to look at the things in it, they provide the structure. In that sense matter/energy and fields (things in space) and space are complementary, you can't have one without the other. You could even say that space is exactly the complement of matter and vice versa. It's very telling that matter/energy warps spacetime, and that spacetime affects the motion of matter/energy. That is a direct consequence of this complementarity. If the amount of matter if finite, then so is the amount of space.

We have no way to know if space is infinite in extent because light travels at a finite speed. Any information we have about space is got through observing matter, and observation is restricted by the speed of light. We can only ever observe a finite volume of space. Everything else is conjecture and philosophy. We can't know what is beyond the event horizon.

One good question to ponder is to ask why space has extent in the first place? I like to think of it like oil spreading on water. In that way space could have a self-repulsion, each bit of space is fighting to differentiate itself to every other bit of space. If space were to start off in a state of zero-extent (a singularity), then it's easy to see how a self-repulsive mechanism could make it inflate wildly and forever. If it's a smooth inflation, then space is finite but ever increasing, if it's an instant phase change, then it could potentially be infinite. It's telling that fermions obey the Pauli exclusion principle, and maybe space is somehow fermionic as well. 

The curvature of the universe is basically a geometric measurement, it's either closed, open or flat. The current consensus is that it's flat, it can't be a mixture.

The big bang didn't happen. The big bang 'happening' is you identifying with an object. When you say I am this thing you create space inbetween yourself and something else when everything is actually tightly packed together. The space between objects and you is imaginary. Like a screen your body is actually bigger than the sun.

Space is flat because reality is flat. Not here and there z axis flat, up and down x and y axis  flat. Like a peice of paper with a drawing on it flat. If you draw a man standing and a wall behind him there is no space in the foreground and the wall and there is no space in between him and the wall and where the 'picture' is being drawn from.

We are still in the big bang and it never happened. Everything is infinitely close together like the man the wall and the perspective of where the man is being drawn from. All these things exist on the same x and y axis when drawn on a paper.

When you make up that the big bang happened you create an imaginary empty space between objects to prove that we are seperate when you are seperated by nothing. Literally nothing.

Yes, Reality is infinite in 3D and in all dimensions. 

One of the Awakenings that changed me the most was the spatial Awakening. Realising that Reality is boundless (there's no edge) and living with this awareness in every moment.

It's such a beautiful thing, as I'm writing this and when I want, I can bask in this boundlessness and it just keeps going on and on.

Is a dream infinite space?

Or are you just projecting it onto the dream unconsciously?

If you can answer that then theres your answer.
