• Why should we care about gravitational waves?

    Gravitational waves are predicted by Einstein's theory — the fundamental theory of gravity that everything else in astronomy relies on — but have not yet been observed. We need to know if Einstein's theory is really right before we can make strong claims about the nature of the Universe. If the theory is indeed correct, finding gravitational waves will give us new insights into the theory, and will give us powerful new tools observe the Universe.

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.
