Physicists are facing a matter/antimatter conundrum: they can’t find a good reason to explain why the universe actually exists.
It sounds like a classic episode of classic Star Trek when someone inexplicably shuts down the warp engines, some imminent threat looms, and — right on cue — Scotty says: “Captain, I canna’ change the laws of physics.”
Physicists from CERN, the world's leading physics research center, have finally achieved a long held goal in quantum physics: being able to see and measure antimatter atoms. Antimatter must exist according to laws of physics, but is notoriously difficult to measure and study.
Antimatter—particles with opposite charge, but otherwise identical to, and paired with, particles of regular matter—may sound like a science-fiction concept, but physicists believe it’s a fundamental product of the Big Bang, which occurred 13.7 billion years ago. Makoto C. Fujiwara, head of particle physics at TRIUMF, Canada’s national laboratory for particle and nuclear physics, and a collaborator at CERN tells Second Nexus, “Physicists believe that anti-matter and matter are created in pairs, but we can’t find any antimatter in the universe in any substantial quantities.”
