The idea that fundamental constants do not actually stay constant over space and time has long played on the mind of physicists. But by looking at how a distant galaxy has absorbed the light from a quasar, researchers have obtained a new limit on how much one fundamental constant -- the ratio of the electron and proton masses -- is changing with time. Their result, which is 10 times more accurate than previous measurements, gives the thumbs up to our current understanding of physics.
