Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a key prediction from Albert Einstein’s theory of general relativity and began a new era of astronomy.

Now, a new gravitational-wave discovery marks the anniversary of this major breakthrough. Published today in Physical Review Letters, it puts to the test a theory from another giant of science, Stephen Hawking.
