Photon radius
WebA proton has a radius. It's about 0.87 fm (femtometers = 10-15 meters). This is defined roughly as the physical space in which the charge of the proton resides. It's obtained via … WebJul 15, 2024 · $\begingroup$ My friend derived the value for the radius of the photon sphere using Newtonian mechanics rather than General Relativity and as far as I can remember he used normal circular orbital dynamics . The derivation yielded 2 values of radius one for the radius of the photon sphere and another being half the Schwarzschild radius.

WebA proton has a radius. It's about 0.87 fm (femtometers = 10-15 meters). This is defined roughly as the physical space in which the charge of the proton resides. It's obtained via election scattering experiments. Muon scattering experiments give a smaller radius at around 0.84 fm. This discrepancy is an unsolved problem in physics. WebIch habe gelesen, dass das Photon keine Masse hat, aber mein Lehrer sagt, dass das Photon Masse hat, weil die Sonne es anziehen kann (wie in den Experimenten zum Beweis der Relativitätstheorie). Ich denke, es gibt einen anderen Grund, das zu erklären. Wie kann ich erklären, dass das Photon keine Masse hat und die Sonne Photonen anzieht?
