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.
This. If it was about robotic propes and landers I would give it a lot more attention. I can even imagine humanity sending unmanned propes to other stars in a century or so, but the first ones would probably be flyby missions. Space could also be full of low tec probes such as Voyager.
This has been my thought too. Humans are already talking about a robotic science mission to the Alpha Centauri star system. Checkout Breakthrough Initiatives Starshot.
If we believe there are other goldilocks planets and have advanced life ahead of ours then I could find it reasonable that they could be sending robotic science missions to other star systems.
