A black hole does not necessarily mean the end. New calculations show: upon turning into a white hole, it blasts out a powerful gamma-ray burst. Such events could be happening right now with tiny black holes the size of the Moon — their explosion would be visible across half the universe. Perhaps this is how we will find invisible dark matter.
🎯 A gamma-ray burst from a Moon-mass black hole would be billions of times brighter than a star, but would last only milliseconds.
