The three possible types of expanding universes are called open, flat, and closed universes. If the universe were open, it would expand forever. If the universe were flat, it would also expand forever, but the expansion rate would slow to zero after an infinite amount of time. If the universe were closed, it would eventually stop expanding and recollapse on itself, possibly leading to another big bang. In all three cases, the expansion slows, and the force that causes the slowing is gravity
I know the biggest problem most people have, and that is reading and understanding what they read.
Read this again: The three possible types of expanding universes are called open, flat, and closed universes.
What are you discussing here! The infinite or which shape our universe has?
There is a big difference between the shape our universe might have,and what shape the infinite dimension has. The probability that the infinite doesn't have a shape is staggering.
Non the less, it doesn't matter what shape our universe has. Because non of the shapes can be infinite.They are all a finite mass of compressed infinite energy that might have different shapes do to a expansion speed.
You have to stop talking about our universe as if it was infinite. Because it is not infinite, it is expanding/changing.
If it was infinite it wouldn't change, and it wouldn't have a shape. The only way we can observe a shape is if there is a space/back ground surrounding it that is different than the shape observed. What would you call that space?
