...else has confirmed Lipman's finding, and scientists have remained skeptical. One reason is that most modern physicists believe that cosmic rays and short-wave light rays (particularly ultraviolet) would destroy any life passing through interstellar space. Professor Backman's hypothesis attacks this objection...
Thus, Backman believes, organisms riding on cosmic particles or meteorites might fly safely through celestial space. He admits they would meet a great hazard when they hit the earth's atmosphere, where atmospheric friction would heat the particles or meteorites enough to destroy all organisms clinging to them. But he believes that the atmosphere may tear the organisms away from their carriers before they get too hot. Any such free-floating bacteria which came in on the earth's dark side, shaded from the sun, might drop safely to earth. Q.E.D...
This new survey of our universe was made at the Harvard Observatory. If was based upon measurements which used the large amount of cosmic dust present in our universe as a basis. These clouds of dust had previously puzzled astronomers. The astronomers were unable to tell whether they were looking at a region barren of stars on the outer extremities of space, or whether the view was merely cut off at some intermediary point by the dust clouds...
...system used to overcome this difficulty was based upon the use of universes other than our own. Where these universes could be clearly seen, it was assumed that no cosmic dust clouds intervened. Thus accurate measurements could be taken. Partial obscuring of universes was also used to locate and chart the location of these dust clouds...
Instead of using cosmic rays or esoteric mathematics for his demonstrations, Professor Ehrenhaft impressed the gathered physicists with little experiments a man can do on his desk with a glass of water, a magnet or two, a compass, some acid and some electric wires...
