You can't achieve the speed of light and here is why - in very simple terms in order to move, something has to get pushed or thrown in relation to something else. Going from a steady state to a moving state - a continuous change in the position of a body relative to a reference point, as measured by a particular observer in a particular frame of reference - a physical movement or change in position or place.

In order to sustain movement a constant change relationship has to be continuously established between a static against the dynamic. As speed increases the dynamic touches more static thus chnaging position at a greater frequency. This is achieved when the static is non-flexible but as the incidence of relationship between the static and the dynamic increases them properties of both change as well.

Remember, the dynamic and the static of made up of particles that are moving almost at a speed C (the speed of light). As dynamic closes in on C the particles do not have the same physical attributes at lower speeds in fact they no longer act like particles at all but rather a fog of sorts that move via peaks and troughs. Think of a falling chunk of silly putty. It behaves like a solid. If thrown at low speeds upon impact it would feel like a solid but at high velocities, s high speed photo releveals that it actually looks like a liquid and infact it beaves like one as well. Matter is like that as well.

Now, dynamic is cruz'n through and it has movement source (rocket, wheel, EM rail, et al). That movement source is made up of the same stuff its just being re-arranged physically by giving off electrons or bigger - regardless these are still 'things' moving near to the sppeed of light C. What ever is reacting, as speed increases it begins to behave very differently, more flexibility which requires even more energy to go faster. At some point there just is enough energy to help the dynamic displace and change position.

Moving at the speed of light would mean that the dynamic would essentially dissolve into the statics it is trying to displace.

Speed of light...impossible to do so for the dynamic.
