Dr. Michio Kaku is a theoretical physicist. Doctor, on a scale of 1 to 10, how excited are you about this UFO release? I would put it at a 10 because we're at a turning point. For decades, we had to rely upon eyewitness accounts of housewives, truck drivers, people would snicker and laugh at them. Now we're talking about huge files that are top secret that for the first time in modern history are being given to the American public. So I'd like to congratulate President Trump for having the nerve to go against recommendations by the FBI and the CIA to release these files so that independent researchers, scientists can go over them and we can make up our own minds rather than having the CIA make up our minds. >> CIA apparently is still fighting the full release. When you hear or see about a UFO that goes like that, up, down, left, right, at 90 degree angles so fast you can't even believe it, what does that tell you? It tells me that that the laws of centripetal force should crush the bones of the people inside the flying saucer. So either there's basically an automated flying saucer, so there are no bones to crack as the thing goes zigzagging left and right, or it represents a very high level of intelligence to create something like that. So in other words, we humans cannot get into a spaceship that goes zigzagging like that. Only aliens can, but even their bones would break. So it must be a very high level of automated computer technology.
