Here’s Why MIT Scientists Are Watching a Black Hole Devour a Star

By watching a black hole devour a star, researchers from MIT were able to determine that it's spinning faster than 50 percent the speed of light.

Apparently, you can learn a lot by watching a black hole eat.

In 2014, astronomers spied a supermassive black hole nearly 300 million light-years away gobbling a star, an event known as a tidal disruption flare or TDE. Given the rarity of such a spotting, they’ve kept a close eye on it ever since.

The hope was that it would teach them something new about how black holes feed. But it ended up teaching a team at the Massachusetts Institute of Technology something else: a new way to measure how fast a black hole is spinning.
