Does light have mass?
Does light have any mass?
If light does not have mass, then how does it have momentum? Does energy have mass? Does dark matter have negative mass? Why is light affected by gravity if photons are massless? Does light have kinetic energy? If light has no mass how do black holes absorb it? How can a photon exist if it is massless? If light does not have mass, then how can it be absorbed by a black hole? Where do photons appear from when mass and energy are combined? What is the mass of our sun? What is mass of the sun? What is actually mass? How can a photon not have mass but still have momentum? Is energy a form of mass? What gives matter its mass? Why does mass become infinite at the speed of light? Can something have negative mass? What is the mass of the Sun? Given that photons have no mass and the speed of light cannot be exceeded, could there be a negative mass that exceeds the speed of light? Is light made up only of photons? What is the size or volume of a photon? How can we say that energy is mass? What is the shape and volume of a photon? What happens to the mass of an object if it travels with the speed of light? How is light produced? Why the mass increase at close to light speed? What fundamentally gives matter mass? If matter cannot be created, what is light? Can an object ever have negative mass? If light has no mass how can a black hole pull it by gravitational force?
