Scientists may have found the first “free-floating” black hole, as it moves around our Milky Way galaxy.
When large stars collapse, they are thought to leave behind black holes. If that is the case, there should be hundreds of millions scattered throughout the Milky Way, left behind after the death of those stars.
But scientists have struggled to find them. Isolated black holes are invisible.
Now, researchers believe they have spotted such a “free-floating” black hole, flying through the galaxy at 100,000 miles per hour.
