Silvano Colombano is a NASA physicist. Scientists Searching for UFO Alien Life UFO News: "We may be finding nothing because we’re doing it wrong, researchers posit. In a 2018 conference paper, Colombano suggests the search for alien intelligence is based on “cherished assumptions” that could be holding it back: that interstellar travel is unlikely, that alien civilizations use radio waves, that other life must be carbon based, and that UFOs have never visited earth. He makes a case for discarding these dusty beliefs and for sociologists to imagine how alien societies might evolve, physicists to do more speculative work on space-time, and energy and technologists to model ways in which technology might evolve in other civilizations."
