  • I thought nothing could escape a black hole, so how does it evaporate to nothing?

    This was the surprising discovery made by Stephen Hawking. Nothing can escape a Black Hole, only if General Relativity is completely correct. It turns out that GR is not completely correct, just mostly correct. If we include quantum mechanical effects, we find that some things can escape.

Come, you lost Atoms, to your Centre draw,
And be the Eternal Mirror that you saw:
Rays that have wander'd into Darkness wide,
Return and back into your Sun subside.

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.
