Known as a physics “cold case”, astronomers have long been chasing Heisenberg and his student Hans Euler’s theory that seemingly empty space can alter the path of light. Dr Lower said the study put physics to the ultimate test, possibly revealing more about the mysteries of the universe. “Our best theories of quantum electrodynamics and quantum physics all still work when you put them in the most extreme magnetic environment in the universe,” he said. “It’s a bit of a relief because it means that our theories still work and there’s nothing broken with physics.
