### Ironing the Wrinkles Out of Spacetime

According to Einstein’s theory of General Relativity, gravity is curvature in the fabric of spacetime. Shockwaves can distort spacetime, causing singularities where the laws of physics appear to break down.

Now two mathematicians at UC Davis have come up with equations that remove these singularities. In doing so, they also extend a theorem called Uhlenbeck Compactness to the setting of General Relativity.
