Search Escalates for Key to Why Matter Exists
I like the idea that while I am trying to figure out what to eat for breakfast others are asking the bigger questions, like... 'why is there something rather than nothing in the universe?'. Actually, I sometimes do ask myself that while eating my cereal and trying to figure out why I do what I do. Some light reading from Quanta magazine.
"According to the Standard Model of particle physics, the universe should be empty. Matter and antimatter, which are identical except for their opposite electric charges, seem to be produced in equal parts during particle interactions and decays. However, matter and antimatter instantly annihilate each other upon contact, and so equal amounts of each would have meant a wholesale annihilation of both shortly after the Big Bang. The existence of galaxies, planets and people illustrates that somehow, a small surplus of matter survived this canceling process. If that hadn’t happened, “the universe would be void,” Schönert said. “It would be very, very boring for us, who would not exist.”"
