WebMar 7, 2024 · That being said, you can see and feel light, but you can’t see space. News alert, recent experiments have shown that a photon has a tiny mass with a new upper limit of 7 × 10−17 eV. Scientists don't want the photon to have mass because it complicates many equations and makes Einstein's idea of gravity false. WebThis is derived from the famous E = mc 2 relationship. Or rather, it’s bigger cousin: E 2 = m 2 c 4 + p 2 c 2. Where E is energy, m is mass, c is the speed of light in a vacuum, and p is momentum. Since photons have zero mass, the equation simplifies to E = pc, and therefore p = E/c. Thus, photons carry momentum because they have non-zero energy. float_bytes pack f float_value

WebAug 25, 2024 · has energy and momentum but no mass, and this is confirmed by experiment to within strict limits. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass. (For details see WebIf we set the rest mass equal to zero (regardless of whether or not that's a reasonable thing to do), then E = pc .
