• How much does a black hole weigh?

    There is no lower limit, in principle, but it'd be difficult to form a black hole lighter than a few times the mass of the sun. Similarly, there is no upper limit, in principle. We expect to find black holes that weigh in the range of a few to a few million times as much as our sun.

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.
