# 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 continuation in the series on Black Holes, examining the Black Hole Stability Conjecture. Asking whether, when black holes are disturbed they return to their stable state after spewing out gravitational waves.
