# Higgs field and Time dilation

I am wondering if the Higgs field is related to time dilation. Photons travel at the speed of light, but muons are very close but never at the speed of light. Would Muons be slowed by the interaction with Higgs field? If so, the bigger the mass, the lower the max speed it can travel. When explaining the relativity, one often quotes a rocket travelling near the speed of light. Maybe it is fundamentally impossible to reach such a speed.

More massive particles do not have lower speed limits. Given sufficent energy, the only speed limit is $$c$$. If you have a fixed amount of energy to give to a particle, then a more massive particle will go slower than a less massive one.
