The beauty of all these theories is trying to understand them.

Now a team of physicists claims to have found the first ever hint of an answer in experimental data. The findings could signal a major crack in the standard model, the theoretical edifice that describes nature's fundamental particles and forces.

As it cooled, all the antimatter annihilated in collisions with matter - but for some reason the proportions ended up lopsided, leaving some of the matter intact.

This asymmetry, called CP violation, could have allowed the matter to survive to form the elements, stars and galaxies we see today.
