Claudia de Rham has spent a lot of her life devoted to exploring the limits and true nature of gravity. As she describes in her new e book, The Beauty of Falling, she skilled to be a pilot after which an astronaut earlier than pursuing a profession in physics.
To simulate free falling, New Scientist took her indoor skydiving at iFLY London, the place she defined how gravity acts on each cell of your physique in the identical method. However, this power nonetheless isn’t totally understood. It doesn’t match into the mould of the different basic forces, and quantum concept can’t but clarify it. For her half, de Rham has sought to make progress by considering deeply about the graviton, the hypothetical service particle of gravity. Each of the basic forces is carried by an equal “boson” particle – some of which have zero mass, whereas others have a really small mass. De Rham needs to know what the graviton’s mass is.
