Physical interpretation of antigravity
Physical interpretation of antigravity
Geodesic incompleteness is a problem in both general relativity and string theory. The Weyl-invariant Standard Model coupled to general relativity ($\mathrm{SM}+\mathrm{GR}$), and a similar treatment of string theory, are improved theories that are geodesically complete. A notable prediction of this approach is that there must be antigravity regions of spacetime …
