What really is a particle? How can massless particles exist? How can it still be a particle if it doesn’t have any mass?

We use the word “particle” to indicate that physical properties come in discrete chunks. Photons may not have mass, but they do have a definite energy, momentum, etc. you can have 1, 2, or 3 units of light energy at s particular wavelength , but you can’t have 1.5.
If we’re talking photons and electrons etc: well, they’re simply not *actually* particles. We just call them that because they kinda behave like little particles most of the time, and what they *actually* are is so damn complicated to understand. So we call it a wave or a particle or both, but it’s kinda not either of them. It is its own thing, whatever we want to call it.
