The author argues that the recent Congressional hearing on UFOs featured credible testimony from military witnesses that UFOs exist and the government has covered up information about them for decades. The author, a retired Navy admiral, vouches for the integrity of the witnesses. He believes society should demand that the government disclose what it knows about UFOs. This could lead to scientific advances that transform our understanding of physics and the universe. Studying UFOs could also improve international security and cooperation. The author contends that failing to study UFOs would be arrogant given how little we understand about the universe.
