Logic tells us that antimatter should have annihilated the Universe. So why hasn’t it?
This rapid series of developments unlocked one of the most momentous and enduring conundrums of physics: if particles with opposite electric charges annihilate one another when they meet, why is there any matter left? And if there’s no more matter than antimatter in existence, then the Universe should have annihilated itself soon after the Big Bang – yet, here we are. This brief animation breaks down this extraordinary, nearly century-long science puzzle, detailing some of the surprising explanations posited by contemporary physicists.
