It is well understood that increasing the verlocity of a body to near c leads to i an increase in its apparent mass also that if two bodies start out a being the same age and one is accelerated to near c when it returns it is apparently younger.
this leads to the question how much energy must be expended to make a mass of 1Kg one second younger ?
