For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask what the inside should look like if Einstein's theory of gravity and the ...

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...

A mathematical model suggests that when a pair of black holes gets quantum entangled, this can give rise to a lumpy space-time tunnel between them ...

The universe is big, weird, and filled with unexpected things. It’s the reason we send space probes to far reaches of our solar system and into deep space, it’s the reason we build telescopes, and ...

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 ...

But there is one concept that could give you hope of escape. Theoretically, the answer to black holes is white holes. If a ...

Astronomy has a way of surprising you. When you believe the universe has yielded its biggest secrets, distant giants and faint signals come along to pose even more questions. Two recent discoveries ...

Two black holes in deep space. (The SXS [Simulating eXtreme Spacetimes] Project via LIGO/Caltech) (CN) — A merger of two black holes “ring” in the cosmos, producing ripples in the spacetime continuum, ...

Lightning might not strike twice, but black holes apparently do. An international group of researchers led by Tel Aviv University astronomers observed a flare caused when a star falls onto a black ...

Measurements of wind in a luminous galactic core reveal dense pockets of gas — a finding that calls for a rethink of how black holes interact with their host galaxies. Read the paper: Structured ...

This is the first confirmed case of a star that survived an encounter with a supermassive black hole and came back for more. This discovery upends conventional wisdom about such tidal disruption ...
