It's not often a new discovery has scientists sounding like a bunch of nihilists, and yet CERN physicist Christian Smorra had this to say to Cosmos regarding a study published this month in Nature: "All of our observations find a complete symmetry between matter and antimatter, which is why the universe should not actually exist."
Scientific models say the Big Bang produced an equal amount of matter and antimatter.
