# 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 short post discussing the possible existence of intermediate mass black holes and why we want to find them.

A post exploring the possible consequences of Primordial Black Holes, ancient types of Black Holes born not out of the collapse of stars, but out of the Big Bang itself.

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.

The Future Circular Collider aims to enhance our understanding of the universe with particle collisions at an energy far greater than the Large Hadron Collider’s.

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.

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.

A post qualitatively explaining the main ideas behind the AdS/CFT correspondence. The breakthroughs in theoretical physics due to the theory are outlined along with the consequences for how we view our universe.

A continuation in the series on Black Holes, examining the inner horizon known as the Cauchy Horizon and its implications on space and time.

How quantum fluctuations in the early universe acted as seeds of structure and eventually led to the formation of the galaxies that we see today.

Contains fairly complex ideas and references to previous posts.
