WebJan 15, 2024 · Is the concept of zero mass solely derived from relativity. 1. Relativity doesn't tell us the photon has no mass, it tells us things traveling at "the speed of light" must not have mass. This, when applied to other theories, tells us the photon should have no mass. The theory [family] describing the photon is Quantum Mechanics, not Relativity. danish pastry house mapleview mall https://blame-me.org
