![]() ![]() But how did it happen? It's one of the Universe's greatest mysteries, but one that we're closer than ever to solving. ![]() Clearly, we exist, as do the stars and galaxies we see, so something must have created more matter than antimatter, making the Universe we know possible. Yet as we look at what's out there, we find that all the stars and galaxies we see are made 100% of matter, with scarcely any antimatter at all. When you look out at the vastness of the Universe, at the planets, stars, galaxies, and all there is out there, one obvious question screams for an explanation: why is there something instead of nothing? The problem gets even worse when you consider the laws of physics governing our Universe, which appear to be completely symmetric between matter and antimatter. NASA, ESA, and the Hubble Heritage Team (STScI/AURA) galaxies to clusters to filaments and the great cosmic web, everything we observe appears to be made out of normal matter and not antimatter. On all scales in the Universe, from our local neighborhood to the interstellar medium to individual.
