September 19, 2019 Stephen Hawking was wrong. Black holes are bald. Back in 2017, a gravitational wave rang across Earth like the clear tone of a bell. It stretched and squished every person, ant and scientific instrument on the planet as it passed through our region of space. Now, researchers have gone back and studied that wave, and found hidden data in it — data that help confirm a decades-old astrophysics idea.
