While some of us may think that there’s gravity on Earth but not in space, gravity is, in fact, everywhere. And despite the remarkable discoveries during the past centuries, in our understanding of gravity, there are still some holes. When it comes to explaining the wider cosmos, it seems we’re missing something.
Claudia de Rham thinks that gravitons, hypothetical particles carrying gravity, have mass. If she’s right, it would change the way we think gravity operates. The effect would touch all sorts of processes, from the early evolution of the universe to the motion of the planets and the fate of the cosmos.
