How can a photon have momentum but not mass? How can an object have momentum without mass? It can do this if it is a wave. A wave transports momentum via its waving motion and not by physically transporting an object with mass. “Momentum” is the directional property of an object in motion that describes its ability to influence another object upon impact.
How do photons exist without mass? Why do photons have no mass? In short, the special theory of relativity predicts that photons do not have mass simply because they travel at the speed of light. This is also backed up by the theory of quantum electrodynamics, which predicts that photons cannot have mass as a result of U(1) -gauge symmetry.
Can a massless object have momentum? However, momentum is the product of mass and velocity, so, by this definition, massless photons cannot have momentum.
Is it possible that photons can have momentum? Particles carry momentum as well as energy. Despite photons having no mass, there has long been evidence that EM radiation carries momentum. (Maxwell and others who studied EM waves predicted that they would carry momentum.) It is now a well-established fact that photons do have momentum.
