Do light photons have mass?

The photon is the particle that carries the energy associated with light, so the answer to whether photons have mass depends on whether it is the energy or the particle that has mass. If it is the energy, then no, photons have no mass because energy can neither be created nor destroyed. If it is the particle, then yes, photons have mass. A photon has about 2.2 micrograms or 0.00000000000000000000000000000000000000000000000002 grams of mass.

Do light and dark matter have mass?

A popular theory that is often mentioned when discussing dark matter is that the mass of photons is equivalent to that of the Higgs boson. It is widely accepted that the Higgs field is responsible for giving elementary particles mass. The Higgs field is also responsible for the shapes of atoms and other elementary particles that make up matter. However, the Higgs field is thought to be a quantum field, which means that it is not localizable. The Higgs field can act on a particle from anywhere

Does light have mass?

Probably the biggest misconception about light is that it has mass. This idea can be traced back to the work of Galileo, and later, to the idea that an object's weight is inversely proportional to the amount of light it emits. However, the idea that light has mass is simply false.

Does dark matter have rest mass?

A competing model to explain the expansion of the Universe says that about 23% of the matter in the Universe is made of unknown dark matter. This exotic matter cannot be detected through any of the experiments designed to detect normal matter, and instead can only be inferred from its gravitational pull. For example, the distribution of galaxies in the Universe points towards a gravitational pull towards a region of space that appears to be there, but which is not made of known matter. If dark matter has rest mass, it would

Does light have rest mass?

No, light does not have rest mass. One way to demonstrate this is by looking at the photon’s energy. The energy of a photon is the amount of work it takes to create or destroy it. It is equal to the amount of energy needed to increase or decrease the photon’s frequency. This is in contrast to matter, which has an associated energy level called the rest mass. The rest mass of an object is a measure of how much energy is needed to create it,
