do all mass less particles travel at the speed of light?
Doc Al said:Yes.
Why?
Massless particles are particles that do not have any rest mass, meaning they do not have any physical weight or mass at rest. They only have energy and momentum, which are related to their frequency and wavelength.
Yes, all massless particles, including photons, travel at the speed of light in a vacuum. This is because they do not have any rest mass and therefore do not experience any resistance to acceleration.
No, massless particles can only travel at the speed of light in a vacuum. This is a fundamental principle of physics known as the constant speed of light.
The speed of light is a fundamental constant in the universe and is the maximum speed at which any particle, including massless particles, can travel. This is due to the relationship between energy, mass, and speed described by Einstein's famous equation, E=mc².
There are some theories that suggest the existence of particles called tachyons, which travel faster than the speed of light. However, these theories have not been proven and are not widely accepted in the scientific community.
