One of the biggest mysteries in astronomy is the question, where did all the antimatter go? Shortly after the Big Bang, there were almost equal amounts of matter and antimatter. I say almost, because there was a tiny bit more matter, really. And after the matter and antimatter crashed into each other and annihilated, we were left with all the matter we see in the Universe.
You, and everything you know is just a mathematical remainder, left over from the great division of the Universe's first day.
But is it possible that the antimatter didn't actually go anywhere? That it's all still there in the Universe, floating in galaxies of antimatter, made up of antimatter stars, surrounded by antimatter planets, filled with antimatter aliens?
Aliens who are friendly and wonderful in every way, except if we hugged, we'd annihilate and detonate with the energy of gigatons of TNT. It's sort of tragic, really.
If those antimatter galaxies are out there, could we detect them and communicate with those aliens?To read more, click here.
