Latest about gravitational waves
Humans could use black holes as batteries, physics paper claims. Here's how.
Black holes are some of the most powerful objects in the universe — and humans could devise ways to harness that power as an energy source, a new theoretical study claims.
Gravitational waves rippling from black hole merger could help test general relativity
"I never thought I would ever see such a measurement in my lifetime."
A nearby kilonova explosion could threaten all life on Earth. But don't worry, scientists say.
Collisions between neutron stars are the most powerful and violent events in the known universe. Would life on Earth survive a kilonova event?
Distorted crystals use 'pseudogravity' to bend light like black holes do
Researchers have used a special crystal to bend the trajectory of light like a black hole would, a phenomenon known as 'pseudogravity.'
LIGO gravitational wave detector breaks 'quantum limit' to find deep universe black hole collisions
The sensitivity of LIGO has squeezed the quantum limit, meaning it can now detect merging black holes and neutron stars on smaller scales and at greater distances than ever before.
New 'galactic atlas' offers stunning details of 400,000 galaxies near the Milky Way
The new Siena Galaxy Atlas is an information gold mine for astronomers and a free gallery of galaxy portraits for the public.
Why Einstein must be wrong: In search of the theory of gravity
Unlike physical theories describing the other three fundamental forces in physics, the general theory of relativity has only been tested in weak gravity.
What are gamma-ray bursts?
Reference Shrouded in mystery for decades, gamma-ray bursts are the brightest explosions since the Big Bang and emerge from only the most violent cosmic events.
