![]() But, that can't be exactly right if matter and antimatter don't mirror each other."īut if matter and antimatter don't mirror each other - if antimatter doesn't obey the same laws of physics as regular matter - our models of the Big Bang will be flawed. It posits that neither observer can say who is really moving and who is stationary. Special relativity assumes that a single unified thing called spacetime splits differently into space and time for observers moving relative to each other. But in a nutshell, if that mirror relationship were not exact, then the basic idea behind special relativity couldn't be exactly right. Physicists Have Captured The First Spectral Fingerprints of Antimatter MIKE MCRAE 4 AUGUST 2017 It's been about nine months since a team of CERN researchers succeeded in their goal of measuring the spectrum of light emitted from hydrogen's mirror particle, antihydrogen. "Explaining exactly why special relativity requires antimatter to mirror matter involves a lot of math. Physicists with the ALPHA Collaboration at CERN have measured for the first time how antimatter absorbs light. If they all end up identical, Einstein's special relatively lives for another day, as Adrian Cho explains for Nature: This result is consistent with the Standard Model of particle physics, which predicts that hydrogen and antihydrogen will have identical light-emitting characteristics, but now physicists have the chance to test even more spectra emissions by using different types of lasers. "It's long been thought that antimatter is an exact reflection of matter, and we are gathering evidence to show that is indeed true," Tim Tharp from ALPHA told Ryan F. The team found that the antihydrogen atom emitted the exact same light spectrum as regular hydrogen atoms put through the same test. ![]()
