use the equation m=mo/sqrt(1-v^2/c^2) to show that travelling at the speed of light or beyond is impossible.
yes bu why u cannot reach c??? what kind of singularity u get??? what does it mean physically???mo is the mass of the object measured in the refrence frame in which it is at rest. m is the mass of the object as measured in a refrence frame moving with speed. in the equation v can never equal to c.....it will....be less because of sqrt 1-v2/c2
