How can photons be particles if they have no mass? Are they just a concept so that light can be rationalized, or do they really exist? Please pardon my ignorance, as I am still relatively young (15.)

mijoon said:Ange, photons are tiny bits of pure energy. Sometimes they act like waves, and sometimes they act like particles. Yes, they really exist but a complete description can be very complicated.
|Orion's Thought| said:And if we could convert energy into matter, could it happen the other way around?
|Orion's Thought| said:Energy can be converted into matter. At the Stanford Linear Accelerator Center (S.L.A.C.), they used high powered lasers and electromagnetic fields to turn light into a tiny amount of matter.
Basically, what you mean by "particle" is probably what we call the classical notion of a particle. That concept is fine and good for classical approximations, but it breaks down at extreme scales.How can photons be particles if they have no mass?

Infinite gravity is a hypothetical concept in physics that suggests gravity may have an infinite range and strength, meaning it could potentially affect all particles in the universe regardless of distance.
Photons are elementary particles that make up light. They have no mass, but they have energy and momentum. They are also known as the carrier particles of the electromagnetic force.
According to the theory of relativity, particles with zero rest mass can still have energy and momentum. Photons have no rest mass, but they have energy due to their motion and momentum due to their massless nature.
If gravity has an infinite range and strength, it would affect all particles, including photons. This means that photons would also be affected by the gravitational pull of objects, even though they have no mass.
Currently, there is no direct evidence for infinite gravity or massless particles. However, the existence of particles with zero rest mass, such as photons, is well-established in physics. The concept of infinite gravity is still a subject of ongoing research and debate among scientists.
