As soon as you can imagine and reason about infinity, you might be able to reason about our universe. “Center” makes sense for most bounded things but might be completely meaningless in an unbounded universe.
Example: the number line. You might be tempted to say 0 is at the center but… there are an infinite number of things on either side of any number you choose.
- alexanderdmitri 5y agoDoes that mean nothing is the center of the number line?
- imoverclocked 5y agoOr everywhere is the center of the number line. Some people argue 0 is the center based on symmetry. My original point is that it is non-trivial to reason about infinite spaces. Since we do not know if we live in a bounded space or not, we can’t assume there is one center. Furthermore, even if we do live in a bounded space, there are different ways of measuring center. Eg: center of mass vs geometric center of a volume. Knowing both and comparing them would be pretty interesting!
- deltaonefour 5y ago0 is the center of an infinite number line. Additionally nobody knows if the universe is infinite.
