In your explanation, how does it repeat?
Also, curvature is a non-local phenomenon. In the sense that if you take a finite volume of space, re-arrange the spacetime however you like, you still have to have the same total curvature inside the volume. You don't have a free hand to reduce total curvature in a volume of spacetime without also altering the boundary.
- graycat 9y agoThanks! Nice differential geometry! I have some good books and plenty of background to read them, but I do need to read them. Want to; have for a long time; came close a few times but always something got in the way; will have to wait until my startup is done.
