Aliens could, in theory, reach Earth but would never truly go home again, according to physicists who say Einstein's laws of relativity turn any near‑light‑speed visitor into a 'time exile.' The warning lands just as the US government publishes hundreds of previously classified unidentified anomalous phenomena case files, and Steven Spielberg's new film Disclosure Day stokes public belief that aliens are already among us.
Enthusiasm about extraterrestrials has been building steadily. Recent polling in Australia, the United States and other countries suggest roughly a third of people think aliens are visiting Earth. The newly released UAP records, stretching from the 1940s to the present, have only deepened that conviction, even though they largely catalogue unexplained sightings rather than prove anything concrete. Nothing in those papers confirms extraterrestrial hardware in our skies, and officials repeatedly stress that most cases remain unresolved rather than otherworldly.
