Minimum speed in the universe

  1. May 25, 2015 #1
    I have a question :x

    Technically, particles, like photons, which don't interact with the higgs field travel at the speed of light.

    wouldn't the absolute minimum speed limit be something that interacts infinitely with the higgs field?

    No. Particles with no rest mass are constrained to move at the speed of light in all reference frames but objects with non-zero rest mass can move at any speed less than the speed of light, including zero.

    An object does not have to be infinitely massive to be stationary with respect to an inertial frame - it only needs to have non-zero rest mass.

    All things (other than those moving at c) move at a relative speed, defined by a reference frame. Therefore the speed can be anything from 0 up < c.
