Yes yes. But you can ask that question, and we can answer it, regardless of whether our space is curved or flat. PI is the same in a flat space in any universe

Yes yes. But you can ask that question, and we can answer it, regardless of whether our space is curved or flat. PI is the same in a flat space in any universe where you ask the question, because we're doing a mental exercise, not measuring it locally.
- TomSwirly 5y ago> PI is the same in a flat space in any universe pi is the same in _any_ space, flat or not. Indeed, the space we are in is probably not flat, but pi is unchanged.
- philipswood 5y agoTrue but Pi (mathematical constant Pi) isn't necessarily the ratio between the circumference and the diameter in those spaces.
