From what I'm gathering from what I'm reading, everything is in
  motion, moving both through space and time. If you add the two
  up, you always end up with the speed of light. Things can travel
  slowly through space and quickly through time (like people and
  most matter) or they can move very quickly through space and
  slowly through time (like nearly weightless particles) - its the
  same energy (e=mc2) but it's all what dimensions its travelling
  on. front to back, left to right, up to down, forward through
  time. "
