Existen partículas SIN MASA? Qué es un fotón?

The video tutorial explores the concept of massless particles, specifically photons, in particle physics. It explains what particles are, how they are detected, and the significance of being massless. The tutorial delves into the relationship between mass, energy, and kinetic energy, using special relativity to clarify these concepts. It highlights that photons, being massless, have only kinetic energy and must travel at the speed of light. The video concludes by emphasizing the beauty of the relationship between masslessness and the speed of light.
