# Solving the Einstein Equation

A post discussing the Einstein equation, the systems for which it can be solved exactly as well as the techniques used to find approximate solutions to more complicated spacetimes.

A post explaining the fuzzball, believed by string theorists to be the true quantum description of a black hole. The theory seeks to resolve the famous information paradox and eliminate the existence of troublesome singularities at the centre of black holes.

A post describing Einstein-Cartan theory; an alternative to Einstein’s General Relativity which could more closely describe the universe, as well as removing some of the big problems posed by general relativity.
