あなたは、存在しないはずだった ― 反物質とCP対称性の破れ【睡眠用サイエンス・51分】

The fact that you are here tonight, breathing quietly—that might actually be impossible. It is believed that at the very first moment the universe was born, every piece of matter had an equal number of its mirror-image counterpart, "antimatter." When matter and antimatter meet, they annihilate each other, leaving only light behind. If exactly equal numbers had been created—the universe should have been empty, everything disappearing at the moment of its birth. Yet, there are stars, galaxies, the Earth, and you. Why did only matter remain? Antimatter, predicted by Dirac and captured by Anderson. The "left-right symmetry" shattered by Ken-Hsiung Kure. The tiny crack, found by Cronin and Fitch, occurring once in a thousand times. The three conditions for the survival of only matter, as demonstrated by Sakharov. And that audacious step taken by Makoto Kobayashi and Toshihide Maskawa, who predicted the quark, something no one had ever seen before, solely through calculations on paper. The universe favored matter and antimatter, but only slightly—just one in a billion. That single remaining antimatter, that one that didn't disappear, has, through a series of events, become you tonight. You may be the gentlest form of the universe's tiny imperfection. There are no difficult formulas. It's alright if you close your eyes and fall asleep midway through. —You shouldn't have existed.
