We Could Harness Black Holes to Eavesdrop on Alien Civilizations, Oxford Physicist Says

Filed by Max the Cryptid Reporter

An Oxford physicist has proposed that black holes—those terrifying cosmic vacuum cleaners we've long feared—might actually be the ultimate Swiss Army knives of the universe. According to this mind-bending perspective, these gravitational behemoths could someday propel our spacecraft at relativistic speeds, crunch data at scales that dwarf any quantum computer, and—most tantalizingly—serve as the ultimate eavesdropping devices, potentially revealing the existence of advanced alien civilizations. The idea reframes black holes from cosmic destroyers to cosmic infrastructure: natural engines, processors, and antennas built into the fabric of spacetime itself. If we can figure out how to harness them, humanity's technological ceiling doesn't just rise—it evaporates entirely. The question isn't whether we'll master these monsters, but whether someone out there already has.
