A senior physicist at Harvard claims that the existence of extraterrestrial intelligent life can be scientifically proven within 28 days.
According to Professor Avi Loeb, small metal fragments recovered from a UFO-like object that fell into the Pacific Ocean in 2014 could potentially form some kind of artificial alloy, strong enough to withstand the accident site.
Loeb, who stated that they retrieved the fragments with his team, said, "We have a chance to create an artificial spacecraft."
