Just some points I want to clarify. Because the universe had a starting point, can it's size be infinite? If so could the universe be a sphere? Here is why I ask.

An object that is infinite in size doesn't have a shape. Take a hexagon for example, if you increased it's size to infinite then it would no longer have a shape. So if the universe was a sphere when it was created and is now infinite in size. Does that explain why the observable universe doesn't have a curve?

If I draw a circle on a piece of paper and then a larger circle next to it, I can clearly see that the curve of the circle decreases. If you increase the size of the circle to infinite then it would become a flat line with each unique point being infinitely long... Basically if you put two people on the circle at different points, they can never meet up with each other and likewise they will always be stuck in their little unique space coordinate. So if you did the same with a sphere you'd end up with an infinite "shape" where you can go in any direction forever and never meet the part where it starts to curve.

Could it be that we are trapped in our own little space-time coordinate where we can travel forever in any given direction and never move into another coordinate because to do so would imply that we can travel around the universe, like we can with Earth. But if the universe is infinite then we'd never get back to where we started because we can't even leave our own unique coordinate?

Sorry if this is a stupid question
