      Our theories predict that antimatter and matter should have been made in equal amounts at the beginning of the Universe. If this is true though, where is it all?
      There are two theories.
      There is possibly an imbalance in the formation of matter and anti-matter and so there is less anti-matter than we thought so all is ok.
      Or (my preferred theory)
      There are lots of anti-galaxies and anti-suns and possibly anti-life somewhere off in a distance part of the galaxy away from all the matter that we can see.

      This question is way outside what I know about physics…. but I really like the idea that there is a lot of stuff out there what we just can’t see.
