Is a circle infinite or finite? How about a ball?
A circle has finite surface area. A sphere has finite volume and finite surface area.
But you can walk straight for all infinity. That's kind of my point when people talk about an infinite/finite universe they conflate the distance that can be travelled with the surface area/volume of it.
Current best measurements suggest we live in flat space.
Is the toroidial thing debunked? I read about it some time ago but didn't dive into it too much
There's no evidence for it, if that's what you mean
Ah I thought there was, thanks for setting that straight
