Scientists have filled in one of the gaps in our knowledge about why the universe exists. They did this by studying something I couldn't possibly imagine: antimatter.
Everything we see is made of matter. I got that far, but what confused me is the mysterious opposite of matter called antimatter. Scientists have unexpectedly discovered that antimatter seems to behave in the same way as matter.
I don't think I'll ever fully understand the results, but I think it's fascinating - it could explain why we exist.
