For years, black holes have been considered the ultimate cosmic traps—regions of immense gravity where anything that falls in, including light, is lost forever. But a new study suggests a radical alternative: black holes might not be dead ends at all. Instead, they could act as tunnels leading to white holes—theoretical counterparts that eject matter and energy back into the universe.

Fast Radio Bursts (FRBs) are brief, intense pulses of radio waves from deep space that last only milliseconds and have puzzled scientists for years. Though their exact origins remain uncertain, a new study in Nature sheds light on potential sources—and they’re not alien signals.
