Document Summary

It would take an infinite amount of energy to accelerate a physical object up to the speed of light. A famous equation what does it mean: mass and energy are (cid:494)equivalent(cid:495, e=mc^2, mass is another form of energy. Joules = 9 * 1016 joules: (1 joule = the energy required to lift a small apple 1 m straight up. , this is a huge amount of energy! Enough to power a country for a year. Idea very similar to the reason why one can(cid:495)t travel back in time.
