Stars, galaxies, planets, pretty much everything that makes up our everyday lives owes its existence to a cosmic quirk.
The nature of this quirk, which allowed matter to dominate the Universe at the expense of antimatter, remains a mystery.
Now, results from an experiment in Japan could help researchers solve the puzzle – one of the biggest in science.
It hinges on a difference in the way matter and antimatter particles behave.
The world that’s familiar to us – including all the everyday objects we can touch – is made up of matter. The fundamental building blocks of matter are sub-atomic particles, such as electrons, quarks and neutrinos.
