Why the velocity of a body cannot ever reach the limit value of the velocity of light in the vacuum ?
A. Because the motion mass m(v) of a body grows with the increasing velocity v, becoming very huge, theoretically infinite, while the velocity is approaching to c. The formula giving the dependence of the motion-mass m(v) on the velocity v is: m(v) = mo : square root of (1 – v2/c2 ) . Moreover, since mass and energy are equivalent, it would be necessary to furnish to the body an infinite energy, and that is physically impossible.
