In region II ( r rS ), future light cones point to the left so that light rays can move only towards the origin. Thus, no light ray, and hence ...

... A wormhole could be kept open by filling its throat, or the region around it, with an ingredient called exotic matter. This is strange stuff which doesn’t exist in the classical physics world, but may be allowed by quantum physics. Exotic matter is repelled, rather than attracted, by gravity and is ...

... In special relativity causality holds due to the hyperbolic nature of the Minkowski metric that clearly separates past from future. In general relativity however, because the Einstein equations are local equations and space-time can be curved by matter, one can construct solutions that exhibit close ...
