I
received a telephone call one day at the graduate college at
Princeton from Professor Wheeler, in which he said, "Feynman, I
know why all electrons have the same charge and the same mass"
"Why?" "Because, they are all the same electron!" And, then he
explained on the telephone, "suppose that the world lines which
we were ordinarily considering before in time and space - instead
of only going up in time were a tremendous knot, and then, when
we cut through the knot, by the pl...14 APR 2012 by ideonexus
The Matter / Antimater Imbalance in the Universe
Physicists have long pondered the problem and may have an answer. It seems that just before the universe was one millisecond old, matter and antimatter annihilated each other in a sweeping extinction. But a tiny asymmetry was built into the universe so that matter dominated over antimatter by one part out of 100 billion. Why the built-in asymmetry? In the first 100 billion-billion-billionth of a second of the universe's history, particles called X particles and their antiparticles were create...In less than the first second of the Universe's existence, 1/100 billionth of the matter was left over from the annihilation with antimatter.
