ok, locally we cannot travel at the speed of light, it would require an infant amount of energy (which is not possible). and the laws of general relativity disallow us to travel at C. thus no LOCALLY we cannot.
HOWEVER
by using space time it is possible to travel at speeds as fast or greater then that of light.
this is generally called the "warp drive" by modern physicists. this is not star trek, or is it?
the general principal in ST remains the key. by using some sort of negative energy (negative energy densities) it might be possible to bend space time in-front of the "spaceship" this would leave the ship locally unmoving. and thus it would not violate Einsteins laws. basically u bend or "warp" space time in-front and behind an object. this encompasses it in a local area of spaetime. since space time moves at C then it is possible for the ship to move at C without actually moving at all, technically. ur using space time to move you or "surf" rather then actualy propelling ur ship at C
a good (but a bit physics heavy read) is miguel alcubierre's "The Warp Drive - Hyperfast travel within general relativity"
if you want a better explanation of the warp drive.
