"Debunked: Interstellar Alien Signal Traced Back to Local Truck Vibrations"
A Johns Hopkins University-led team has found that the sound waves previously thought to be from a 2014 meteor fireball near Papua New Guinea were likely vibrations from a passing truck, casting doubt on the belief that materials recovered from the ocean last year were of alien origin. The team's research suggests that the materials are ordinary meteorites or particles produced from other meteorites hitting Earth's surface mixed with terrestrial contamination, and they identified a more likely location for the meteor more than 100 miles from the initially investigated area.
