Question: What is the weirdest force you have discovered?

Steven Thomson answered on 16 Jun 2015:

There are only four fundamental forces (gravity, electromagnetism, and the strong and weak nuclear forces) and they were all discovered before I was born, so I haven’t actually discovered any new forces!

The weirdest thing I’ve discovered, though, is probably how the electromagnetic force behaves in a really cold liquid called a superfluid – in my current research, I think I’ve found this force does something no one’s spotted before, which is exciting.
