c is a conversion factor between space and time coordinates when we project them into a space that we can intuitively grasp. the obsession with the 'speed of light' always seems a bit senseless in this context - its taking a concept which is known to break down in some limit and then applying it right at that limit. this is bound to be confusing. really the speed of light is like infinity in the geometry of our universe... it just happens unfortunately that the geometry is not as simple as an infinite euclidean space with an independent time coordinate so we end up attributing a bad interpretation to the 'speed' of light.
