Resonance

Now i know this is a very late post but i figured i would say my piece. Now im not going to even try to refute Einstien...However, it was said that it was impossible to hit 90 MPH in a car and that the speed would tear your body apart, that is up until it was broken... also the same thing was said about the sound barrier that it would kill you or tear the vehicle apart, again this was said until it was broken. so in my honest opinion only time will tell if we can hit lightspeed or not.
