Physicists: New approach to antimatter offers promising results
According to the Standard Model of our universe, beginning with the Big Bang, there is no difference between matter and antimatter (although they annihilate each other on contact). Why then do we see all matter, no antimatter? A group of physicists decided to test a new theory: From ScienceDaily: About ten picoseconds after the Big Bang — right about the time the Higgs boson was turning on — the universe was a hot plasma of particles. “The technique of dimensional reduction lets us replace the theory which describes this hot plasma with a simpler quantum theory with a set of rules that all the particles must follow,” explains Dr. David Weir, the corresponding author of the article. “It turns out Read More ›
