A point at which the curvature of spacetime becomes infinite. Singularities can form — for example — when too much matter is squeezed into a region which is too small. Singularities are found at the center of a Black Hole, at the beginning of the Universe in the Big Bang, and at the end of the Universe (if it ever comes) in the Big Crunch. Many scientists believe — though there is no solid evidence — that all singularities in the present Universe lie hidden behind Event Horizons. This is the "Cosmic Censorship Conjecture".

Time writes no wrinkle
on thine azure brow,
Such as creation's dawn
beheld, thou rollest now.

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.
