For a very long time, the scientific community has been wary of studying UFOs, and the scientists themselves hesitate to talk about their beliefs of unexplained aerial phenomena.
But that attitude is changing, and many scientists are joining the discussion without fear of ridicule.
"UFOs are real phenomena. They are artificial objects under intelligent control. They're definitely the craft of a supremely advanced technology," says physicist Eric Davis, a researcher of light-speed travel.
Davis, a research physicist at the Institute for Advanced Studies in Austin, studies propulsion physics, which he hopes will one day allow humans to travel easily and quickly through our galactic neighborhood.
