Why are we here? This is an age-old philosophical question. However, physicists like Will Cairncross, Dan Gresh and their advisors Eric Cornell and Jun Ye actually want to figure out out why people like us exist at all. If there had been the same amount of matter and antimatter created in the Big Bang, the future of stars, galaxies, our Solar System, and life would have disappeared in a flash of light as matter and antimatter recombined. But we know that’s not what happened. After matter-antimatter recombination, sufficient matter remained to form galaxies, stars, planets, and physicists who wonder why on Earth things turned out the way they did.

The JILA team thinks precision measurement of the shape of the electron may help them figure out the answer. They think that in the beginning of the Universe, there must have been a slight excess of matter vs antimatter caused by tiny asymmetries in fundamental particles such as the electron. If, for example, the electron is ever-so-slightly egg-shaped (rather than round), then it may help explain why the scientists doing the experiment and the rest of the material Universe exist.
