SPACE: Could Black Holes Reverse Time?
As a massive star collapses into a black hole, it sends out a brilliant SOS signal in the form of ultrabright gamma-ray bursts. Now, scientists have found something very peculiar about those mysterious signals: They seem to reverse time. Well, sort of. A new study, published Aug. 13 in The Astrophysical Journal, has found that these gamma-ray bursts are time-reversed, meaning the brilliant light wave is spit out one way and then sent out again in the opposite order. The researchers said they have no idea what’s causing these time-reversed gamma-ray signals, but they added that the physics around black … Read more
