Hello all, I spend a LOT of time learning random bits of science, math, etc. But this is my form of entertainment, not a hobby or profession. But that leaves tons of gaps. So I decided to finally start asking some of the weird questions I have in my head. I am sure some will be dumb or have obvious answers but whatever.
So the main 2 that compelling me right now. First one is: If (and I know this is entirely impossible) I was able to pick a direction and start traveling BILLIONS of time the speed of light WITHOUT traveling backwards in time, (maybe through a warp funnel or something), and I was able to continue forever, at a rate of movement faster than the expansion of the universe. Again, I know it's not possible. Basically I am asking whats at the edge of the universe. Or does it fold on itself like a crazy klein bottle?
My second question... I am not sure if this goes here or not. If you draw 4 boxes next to each other, 2 side by side and 2 just below also side by side (so they make one bigger box), all of the inner edges will be touching with no gaps. If you draw 4 hypothetical circles (they are not real and the lines that make up the circles have no dimensions), the edges of the circles will touch but they will leave diamond shaped gaps in between them. If you then draw a circle in that gap, it will create more smaller gaps around it. Continue this forever. Is there a moment when these hypothetical circles become points? I guess another way of asking, is there a smallest quantifiable amount of space?
