To be fair to Mallet he was constructing a model of the universe...His Ring Laser (Electromagnetic) represented the universe in which Einstein postulated that everything returns to its point of origin, like when he said if he stood on a hill and shot an arrow into the universe it would at some point come back and hit him in the back Mallett construed this as a circular universeNope. Light doesn't travel in circles. And no one has ever verified that light has mass. It's all just make believe.
Maybe he had a very long armI vaguely recall watching a documentary & our science teacher telling us also, that there was a time hole made in around 1880s - 1920s, were someone put their hand at one end of the room through the time hole & it ended up at the other end of the room were the second hole was stationed. anyone know of that one?
