WebNov 16, 2024 · However, light does bend when travelling around massive bodies like neutron stars and black holes. This is explained by Einstein’s theory of general relativity. We are all familiar with massive objects being influenced by gravity. For instance, think of a planet orbiting the sun. As the planet moves, a centripetal force acts on it, which ... WebOct 9, 2011 · In relativity ALL energy contributes to gravity, and so a photon has 0 mass yet it does have gravity and it can, and does, travel at c to the best of our knowledge. Check out wikipedia for more. Thanks Drakkith, now i understand. So a photon always has 0 mass, so its gravity comes from its energy, not mass. 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 ... chucking a wobbly

WebIn the best theory that we have, photons have zero rest mass. And this property of photons is important for the internal self-consistency (renormalizability) of the theory (the so-called Standard Model of particle physics.) So basically, the … WebApr 1, 2014 · Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. Now there is an interesting additional effect contained in the general equation. If a particle has no mass ( m = 0) and is at rest ( p = 0), then the total energy is zero ( E = 0). design your own wood sign with moldingWebRegardless of the photon generator characteristics, onboard photon rockets powered with nuclear fission and fusion have speed limits from the efficiency of these processes.

WebSep 12, 2024 · This is not because the mass pulls on the photons directly, but instead because the mass warps the space-time through which the photons travel. Imagine a bowling ball on a mattress. WebAs far as we know, photons are massless. If they do have a mass it must be less than 10-54kg, less than a trillionth that of an electron. Most of the misconceptions your teacher has comes from various inappropriate versions of energy, mass, and momentum. This isn't the case, gravity affects the paths things travel on, including the paths of light.
