My father, born in 1912, explained Einstein thus: "The kinetic energy of a moving object is 1/2mv^2. So when the object has accelerated to light speed, you have wasted half of its mass. And when you brake down from light speed you have to waste the other half. So may be you can travel faster than light, but cannot Ever Arrive Anywhere." At age 12 I thought this was quite brilliant, because he was not educated in this and he thought 12 Volt battery was as dangerous 220 Volt plug.
