A circle or loop would appear to approach dead flat as one examined increasingly smaller pieces of it (approaching size 0 relative to loop size). Perhaps this could be analogous?

Thanks, George. :smile: Is it correct that curvature would not be constant throughout the universe because at a local level it would be affected by massive objects? If so, when you speak of measuring spatial curvature, are you speaking of a measurement analogous to temperature in that it is an...

Given the curvature of space-time, are all lines through space also loops? If so, are the loops always circular? If the loops are not always circular, what determines the shape of the loops?
