WebAccording to Newtonian mechanics, light should be able to escape from a black hole. It views gravity as an effect between massive objects, so a massless photon shouldn’t be affected by a black hole. General relativity treats gravity as an effect arising from matter warping space-time. Light and photons will follow a straight line through ... WebOct 27, 2024 · An odd space experiment has confirmed that, as quantum mechanics says, reality is what you choose it to be. Physicists have long known that a quantum of light, or photon, will behave like a particle or a wave depending on how they measure it. Now, by bouncing photons off satellites, a team has confirmed that an observer can make that …
