Gravity can transform into light, mind-bending physics paper suggests

Gravity can flip itself into mild, however provided that space-time behaves in simply the best manner, a analysis workforce has discovered.

Below regular circumstances, you can not get one thing from nothing. Particularly, the Normal Mannequin of particle physics, the reigning idea that explains the subatomic zoo of particles, often forbids the transformation of massless particles into large ones. Whereas particles within the Normal Mannequin consistently become one another by means of varied reactions and processes, the photon — the massless provider of sunshine — can not usually become different particles. But when the circumstances are excellent, it’s attainable — for instance, when a photon interacts with a heavy atom, it might probably spontaneously break up off to turn into an electron and a positron, each of that are large particles.
