Scientists found that the black hole at the center of our galaxy is spinning so fast its dragging space-time along. AdvertisementA team of scientists has discovered that the black hole at the center of the Milky Way galaxy is spinning so fast that it's squishing space-time. Advertisement"But if you have a rapidly rotating black hole, the space-time around it is not symmetric," Daly said, according to CNN. "The spinning black hole is dragging all of the space-time around with it … it squishes down the space-time, and it sort of looks like a football." That may sound alarming, but don't worry; the black hole is way too far away to affect us here on Earth.

The researchers confirmed that the black hole is spinning, which causes what is known as the Lense-Thirring effect. “But if you have a rapidly rotating black hole, the space-time around it is not symmetric — the spinning black hole is dragging all of the space-time around with it … it squishes down the space-time, and it sort of looks like a football,” she said. Black holes and galactic historyKnowing the mass and the spin of a black hole helps astronomers understand how the black hole might have formed and evolved, Daly said. However, a black hole that was made with accretion of surrounding gas would see a high spin value. “The question of whether our central galactic black hole rotates or not, or how fast it rotates, is quite important,” Stojkovic said in an email.
