By the Book 12

Ok so here’s the interesting part (I’m feeling a little better by the way, I went to the doctor and he gave me pink mold in a bottle, I can’t get over the whole Penicillin thing), so ya know the whole matter-antimatter thing? Well that applies here. When temperatures started to drop at the end of the hadron era annihilation happened more frequently than creation and all the hadrons started to disappear. But we still have them? So why do we have them? Well according to Harrison its because there were slightly more matters than antimatters to begin with. He says the ratio between the fraction that survived (the difference between the matters and antimatters) and the total number that there was at one point is about 10^-9. In other words only about 1 in a billon of the original matters survived. And yet this amount of matters is what makes up the whole universe as we see it today. And when all the rest of the matters annihilated with the antimatters they created a whole bunch of energy. And this energy is what we see today as the photon and neutrino backgrounds. Our universe has done a pretty amazing turnaround since its beginnings no?

I guess matter and antimatter shouldn’t be plural.
