Qfwfq Posted October 12, 2005 Report Posted October 12, 2005 Right dasraiser, the light saber in Star was is very short and a beam of that length actually will seem to move rigidly but a light-year-long beam wouldn't. I don't know why Paul says what he says. :surprise: As for Unc, don't take his every word for gold. RQFT doesn't care whether or not G is 0. Quote
dasraiser Posted October 17, 2005 Author Report Posted October 17, 2005 i guess it would probably take just a bit more than a year for the light saber to fully switch on anyway ;) regards Quote
Greg_G47 Posted November 3, 2005 Report Posted November 3, 2005 What happens to a beam of light when you change its direction? The same thing that happens to a stream of water. Take a hose spraying a steady stream and turn it. Some water continues in the original direction, some is released along the arc of rotation, and in 1/2 a second or so after the hose reaches its final position the water reaches the point it has been aimed at. The idea of shadows moving faster than light assumes a beam of light is a rigid object and not a stream of particles, which is where the misconception comes from. Quote
