29. An astronomer at Ohio State University has registered a signal that is believed to be sent by an extraterrestrial being.
On August 15, 1977, astronomer Jerry Ehman recorded a radio signal using the Big Ear telescope at the Ohio State University. The sound was intense, and it lasted 72 seconds. Ehman wrote “Wow!” on the printout, calling it “The Wow! Signal.” Nevertheless, the signal was never heard again, which, despite subsequent astronomers pointing radio telescopes in that same patch of sky, led many to assume it may have been extraterrestrial.
Others claim that it was just a comet that the telescope had picked up, but Ehman doesn’t think that’s accurate. Many people believe the signal detected was just a malfunction in the telescope, according to Live Science.
In a 1997 paper, Ehman resists “drawing vast conclusions from half-vast data”—acknowledging the possibility that the source may have been military or otherwise a product of Earth-bound humans. Regardless, it remains the strongest candidate for an alien radio transmission ever detected.
30. In 2015, the beachgoers in Rhode Island witnessed an unusual blast that some conspirators consider suspicious.
In July 2015, a mysterious blast on Salty Brine Beach in Narragansett knocked people off their beach chairs and wounded one person. Witnesses said they heard rumbling in the ground just before the blast.
“There was a massive bang and I saw the actual rocks shift and move,” one witness told CBS Affiliate WPRI. “And I started screaming, ‘Get up, get up!’ The same time I’m screaming, the sand erupted, threw my sister from there, like a live canon, face-down, unconscious 10 feet away.”
Some conspirators claim that there may have been explosives hidden in the sand, but there is no evidence that would have pointed at that. Dan Bidondi of “Infowars” tried to promote the idea that the beach was dangerous due to explosives while questioning beachgoers in Rhode Island on his YouTube channel. According to the Providence Journal, copper cable corrosion hydrogen is likely to cause the Salty Brine blast.
