I am not impressed or interested in your self-serving obscurations. As for the Sagan issue, as I distinctly recall that I posted the citations to those articles, one with Sagan and one of his doctoral students at the time at Harvard, David Morrison (check him out on Wiki), and a second paper. possibly just with Sagan or just with Morrison, in 1967 or 1968. And No, I wasn't at Harvard, but working at the Smithsonian Astrophysical Observatory, located at 67 Garden Street, in Cambridge MA. One or both were printed in The Astronomical Journal. I also told you that my real name is NOT Grayson, but apparently you couldn't connect the dots. As for Roswell, for someone who firmly believes in the most fantastical and improbable interpretation of QM, I don't see that you're in a position to cast aspersions on my belief in the Roswell Incident. What do you think the US Navy pilots were chasing fairly recently? Do you have a clue, or do you just like to demonstrate how closed you are to unusual phenomena? You regard yourself as an objective analyst of scientific facts, but you're anything but; just another fool shooting off your mouth. AG By the way, Erwin Schrödinger made no secret of being a sexual libertine, but now his politically incorrect lifestyle is catching up with him, there is a move afoot by the same sort of imbeciles who dreamed up the phrase "defund the police" to change one thing in the equation, its name. They're also trying to change the name of the James Webb telescope. > > *> Further, in the case of a free particle, the solution changes its form >> as tIme goes backward,* >> > > Of course the solutions change depending on if time is going forwards or > backwards!
