• Do black holes make time travel possible?

    Maybe, but not for humans just yet. Black holes can help give rise to wormholes. A wormhole is a bridge from one part of spacetime to another — a bridge through space, or through time, or through both. However, wormholes are almost certainly unstable — they will collapse very quickly, unless held up by something. It might be possible that some advanced civilization could figure out how to keep a wormhole open, and then use it for traveling through space and time.

Four Areas of Science


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.

twelfth-century masterpiece

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.
