LOL Kinetic energy increase quadratically for sub-relativistic speeds only.

Kinetic energy

E = (m * v^2)/2 + (3*m * v^4 )/8*c^4 + (5*m * v^6)/16*c^6 …

and so on, so kinetic energy increases infinitely faster than speed, thus it impossible to reach c, because it requires infinite amount of kinetic energy.

Why? Because of rules of wave propagation.
