So... warp travel is light speed at warp one? Light in a Vacuum is "c" and deemed to go at that rate because it is unobstructed by any object and has a free path. So I wonder about creating an unobstructed path for mass to move within. If an object with mass moves unobstructed in space with a shell of influence such as like a solar system or galaxy could it move at the same rate with internal gravitational fields associated at the rate "c"? Clearly Star trek suggests ships move faster than the unobstructed vacuum travel of light. Sub-space is space around the ship which the ship is traveling as it affects the ship within? It would suggest the shell of influence in a warp field allows subspace to move the ship beyond normal space. Does sub-space slip past space faster than our space that "c" is measured in? I wonder if subspace field/shell of influence slips past normal space even when ship travels at sublight speed while in the containment of the field.
