...more than 1,500,000 times the energy of the particles shot out by the University of California's powerful bevatron, and 50 million times the energy of a splitting uranium atom in an Abomb. The "something," Physicist Schein thought, was most probably an illusive particle called an antiproton (negative proton), which theoretical physicists have long guessed about, but never observed...
Like most careful physicists, Dr. Schein does not like to speculate about the possible origin of antiprotons. It is quite possible, says he, that remote stars may be made of "reversed matter," whose atoms have negative antiprotons in their nuclei and positrons (positive electrons) revolving around them. There would be no way to tell; the reversed matter would send out the same kind of light as ordinary matter. It would behave itself normally as long as it stayed at home. But if particles from an antiproton star should wander into a region, like the earth's atmosphere, where...
Professor Rossi believes that the original particle may have been an antiproton that hit a normal proton in the brass plate and annihilated it. Apparently the encounter produced nothing but energy, and it produced too much (about 1.3 billion electron-volts) to be accounted for by any other process...
