Einstein's Equations

A set of "tensor" equations Einstein devised to describe how mass warps spacetime. The set of equations may be written as \(G = 8 π T\), where both \(G\) and \(T\) each represent a set of ten quantities. The \(G\) quantities represent the warping of spacetime, while the \(T\) quantities — the "Stress-Energy tensor" represent the mass.

About SXS

The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.

The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
