The term hyperspace or hyperspace velocity; refers to particles that are traveling beyond the speed of light; and beyond our normal space that we physically interact with.

 

In hyperspace; particles can travel through your body without damaging it; since the particles interact with normal space at the subatomic level.

 

In normal space, hyperspace particles do act upon normal matter; we call this interaction Gravity; it is an invisible force that acts on all normal matter in the Universe.
