After undergoing a 5-year upgrade, the world's most powerful gravitational wave detector is back online and hunting for the tiniest of tiny fluctuations in spacetime.
Has Stephen Hawking found the 'emergency exit' for information falling into a black hole?
A new spacecraft will test ideas to find gravitational waves in the universe.
A newfound giant black hole nearly as massive as 7 billion suns is dozens of times larger than astronomers expected given its host galaxy's size, researchers say.
For the first time, the mass of a binary pulsar pair has been precisely measured, but it was a race against time before the extreme gravitational warping of spacetime caused one of the dense objects to blip out of view.
How does time stop everything from happening at once? What mechanism drives time forward, but not backward? Continue reading →
Dimensions are complicated. Wrapping your head around how many there are can give you a headache. Trace explains everything you should know about them.
