In 2014, an Interstellar Signal Linked to Aliens Was Detected

Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new Johns Hopkins University–led research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.

“The signal changed directions over time, exactly matching a road that runs past the seismometer,” said Benjamin Fernando, a planetary seismologist at Johns Hopkins who led the research. “It’s really difficult to take a signal and confirm it is not from something. But what we can do is show that there are lots of signals like this, and show they have all the characteristics we’d expect from a truck and none of the characteristics we’d expect from a meteor.”
