Stockholm, Oct. 26, 1959-Two American atomic scientists were awarded the 1959 Nobel Physics Prize today for the discovery of the antiproton, proving that matter exists in two forms—as particles and antiparticles. They are Italian—born Dr. Emillo Segre, 69, and Dr. Owen Chamberlain, born in San Francisco.... According to one of the fundamental assumptions of the new theory, there may exist another world, or an anti-world, built up of antimatter. This anti-material world would consist of atomic and subatomic particles spinning in reverse orbits to those of the world we know. If these two worlds should ever clash, they would both be annihilated in one blinding flash.
In this statement, the following propositions are put forward:
1. There is an anti-material atom or particle which is made up of the anti-qualities of material atoms.
2. There is another world besides this material world of which we have only limited experience.
3. The anti-material and material worlds may clash at a certain period and may annihilate one another.
