Chris Lehto has admirable bona fides (BS material science, USAFA, 12+years F-16 pilot), but his chutzpah to start his video by stating: "If you are like most people, including all of our mainstream scientists, you are probably confused by experiments like the double-slit experiment, how does gravity work, how can light propagate through empty space . . . ", leaves me suspicious of any content he presents. I find the video to be a spit-balling of random ideas. Those that find his talks engaging - enjoy what you like.
