  • Will the Universe collapse back to a point again?

    We can't quite tell yet. The Universe is right on the edge between expanding forever, and collapsing back to a point. There may be a reason for this that we don't yet understand, or it could just be a coincidence. Only more astronomical observations, and better theories, will be able to tell us for sure.

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.
