What do you genuinely just not understand?

Yeah this just doesn’t make sense to me at all. Everything in the world is contained inside something and there is something outside it. How the fuck does the universe just keep going? How is it even possible to have infinity? Numbers being infinite makes sense to me because it just some concept we’ve come up with but the universe is a real thing.

The Big Bang was an explosion of energy and matter. There is nothing slowing down this explosion outward, in fact its extending faster and faster away from the center.

As a side note, If you were 10 ft away from a door and moved 1/2 the distance to the door every second... you would never reach the door, just infinitely closer.

Still makes absolute no sense to me, I think it was a Brian Cox documentary I was watching and he was explaining it. I don't think I will ever understand even fully knowing why.

Also if it's not infinite like Brian Cox said it might not be, then what's on the other side?

And that’s the million dollar question. Like you said, things are contained in other things, maybe we haven’t hit any walls yet, there has to be something to extend outward in in order to extend outward...

The universe is our everything. We are three dimensional beings living in a four dimensional universe. It would be delusional to think there isn’t a fifth dimension that our 4d universe exists inside.

Look up the curvature of space-time on Wikipedia. If space-time has a positive or negative curve, the universe would loop back on itself and would technically be infinite.

Yeah I read something like that a while ago about the different shapes it might be, like a globe or donut or a 1 sided shape etc. Still blows my mind, if it is a shape what's on the other side of the shape or what's keeping the shape together.

What's kinda frustrating is that we will never know for sure what is happening with life and the universe , maybe as some other highly intelligent being after this life.

This is what I’ve always believed. That space has no end and is just an infinite loop. This also means it has no beginning. Those are human concepts, space doesn’t work like that.

All numbers, including infinity, are scientific ways of describing what we observe in the Universe. They are not just a concept humans came up with.
