Theory of Relativity in Space: Latest science, tests and images

Now the elusive ripples in spacetime have been found, scientists are planning for a rich future for using gravitational wave observatories to unmask the warped side of cosmos.

A theoretical five-dimensional black hole shatters Einstein's theory of general relativity.

Black hole theoretical physicist Stephen Hawking has some thoughts on the discovery of gravitational waves.

The merging black holes generated a gravitational wave signal from 1.3 billion light-years away -- but which direction did they come from?

The first-ever direct detection of gravitational waves will open up an entirely new window on the universe, researchers say.

Neil deGrasse Tyson took the stage at Columbia University to speak after a historic result was revealed: the first direct detection of gravitational waves.

Read all about the mysterious spacetime ripples known as gravitational waves, and what their detection means for astronomy.

To spot gravitational waves directly for the first time ever, scientists had to measure a distance change 1,000 times smaller than the width of a proton. Here's how they did it.
