Since its discovery, Einstein’s theory of Relativity has fascinated both scientists and common man alike. It is due to this fascination that the ideas like curved space, singularities are popular among the general public.
The concepts of Relativity are not of everyday experience and thus, somewhat hard to visualize. Same applies to the concept of spacewarps. By the theory, the presence of masses in space curves its geometry. Gravity, which Newton suggested as a force, is the curvature of space as per the relativistic perspective. When it comes to spacewarps, Euclidean Geometry, which is based on flat space-time does not hold good. Bodies following straight paths (as appears to them) in this curved world actually move in circular or elliptical paths. Even light, when moves through this space of high curvature (like the vicinity of a massive star), appears to be deflected by the star. But though spacewarps are discovered through relativity theory, it is these spacewarps that possibly are the limitations to this theory.
Relativity, in one of its postulates, suggests that laws of nature are same everywhere. But this theory is based on nearly flat and not extremely curved space-time. The theory predicts the breakdown of itself when subjected to very intensely curved space, as in singularity, or space-time boundary. The problem of singularities can be solved with the help of the Quantum Theory.
