    The two known massless particles are both gauge bosons:

    the photon (carrier of electromagnetism) and

    the gluon (carrier of the strong force)

    Also, gravity

    per relativity theory traveling thru a worm hole is much faster than the speed of light

      Light is electromagnetic radiation...but not all electromagnetic radiation is visible light.

      Time is not a fabric where you can weave space with.

      As to your "monthly pay"...you can slow that speed down by putting your pay into a different medium...like a savings account for example.

    Photons always move at the speed of light in a vacuum.

      You're right Hammer. In fact photons always travel at the speed of light C in a vacuum. But when they travel into and through some other medium, their average speed c through that medium will be slower than through a vacuum. Which is why we have the refraction index N = C/c; where c <= C.

      Lon - gravitational waves and changes in gravity through the motion of a gravitating source , travel at the speed of light.
