Wait a second. The low-energy laws of physics is *us* isn't it? I mean, the laws that govern our everyday lives?

Yup, precisely. So it's conceivable, for instance, that a different region far away could have different decay rates for radioactive atoms, perhaps a different strength of the electromagnetic force. Stuff like that.GreatBigBore said:Wait a second. The low-energy laws of physics is *us* isn't it? I mean, the laws that govern our everyday lives?
If the universe is curved and closed, it may be in the form of a 4-dimensional spheroid. Just like on a 3-dimensional sphere, if you head in one direction long enough, you will arrive back at your starting point.GreatBigBore said:And your basis for this is?DaveC426913 said:We would arrive back at our departure point.GreatBigBore said:Ok, but "out to the limits of our vision" brings me back to the question: what do we think might be there, or what might I experience if I tried to get "there"?
