Bad news, everyone! New measurements show that electrons are perfectly round. This is a problem because it means something's still seriously wrong with a critical theory that's supposed to tell us why the universe exists.
Question: What do you get when you mix a cappella, sock puppets, string theory and Queen? Answer: The geekiest (and astonishingly good, musically speaking) cover of "Bohemian Rhapsody" EVAR. Easily the greatest physics-themed cover of the classic we've ever heard. Seriously. The thing's a masterpiece.
If you've ever looked at a model of the atom, you'd probably guess that electrons are spherical. But these elementary particles are actually slightly egg-shaped...and proving that could mean trouble for one particular model of subatomic physics.
Supersymmetry holds that all the subatomic particles we know have counterparts that are almost exactly the same, only much, much heavier. But the Large Hadron Collider hasn't found any supersymmetric particles yet, and they're running out of places to hide. Will we have to come up with a new model for subatomics?
Yesterday, we presented a comprehensive guide to the world of subatomic particles, exploring all the known elementary and composite particles. But now it's time to put certainty to one side and explore the wild, mind-bending world of undiscovered particles.
