Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward the Big Bang, and the equations run into a singularity, a point where ...

On the eve of the recent major snowstorm, students, faculty, and staff gathered in the Nixon Lounge of Hawthorne-Longfellow Library to listen to Thomas W. Baumgarte, William R. Kenan Professor of ...

For decades, one of the biggest questions in cosmology has remained frustratingly out of reach: what, if anything, existed ...

We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy ...

Studying the equations of General Relativity and beyond, both analytically and with state-of-the-art simulations. Novel numerical and mathematical approaches can shed light on the structure and ...

This post finds us at the cutting edge of physics, numerical general relativity. Because we haven't perfected mind-to-mind transmission of information, we won't actually be able to cover in any real ...

Rogue black holes kicked from their galactic lairs are among the surprising predictions made by physicists using powerful computers to solve Einstein's equations of general relativity. David Appell ...
