An illustration of two black holes about to merge and emitting copious gravitational waves. And as the numbers of gravitational-wave observations have increased, physicists’ careful modeling is ...

A team of physicists has proposed that the Big Bang did not mark the absolute beginning of everything but instead occurred inside a collapsing black hole, meaning our entire universe may exist within ...

A decade ago astrophysicists at the Laser Interferometer Gravitational-Wave Observatory (LIGO), operated by the California Institute of Technology and the Massachusetts Institute of Technology, ...

Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA collaboration, a research team that includes Columbia astronomy professor ...

Ever wondered what would happen if you fell into a black hole? According to Einstein’s Theory of General Relativity, you would be crushed by the powerful gravity of its singularity: the center of a ...

A new study achieves unprecedented accuracy in modelling extreme cosmic events like black hole and neutron star collisions by calculating the fifth post-Minkowskian (5PM) order, crucial for ...

The mathematical analysis of black hole spacetimes has evolved into a rich inter-disciplinary field that employs advanced techniques from differential equations, spectral theory and microlocal ...

Karl Schwarzschild first stumbled upon black holes in 1916, but for a long time they weren’t really a thing. “Black holes were discovered as a purely geometric object — in a sense, just empty space.

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...
