Hmm, it's been a while since I took that physics course, but here goes . . . Given an observer at rest (time interval To), and an object (time interval t) travelling with a velocity v, the amount of time dilation for the object is given by the Lorentz transformation (c = speed of light ) : 2 2 t = To / sqrt(1 - v / c ) This gives time dilations of : v/c t 0.00 1.00 ( That seems right ) 0.000322 1.000000056 ( 100 km/h = 61 mph ) 0.50 1.15 0.90 2.29 0.95 3.20 0.99 7.09 0.999 22.37 0.9999 70.71 0.99999 223.61 0.999999 707.11 1.0 core dumped - division by zero (which is why, according to today's physics, you can't travel *at* the speed of light, though theoretically you can travel faster) The time dilation for 100 km/h corresponds to about 1.75 seconds / year. By replacing time by mass, the "mass dilation" can also be calculated. -- Andrew Folkins ...ihnp4!alberta!andrew All ideas in this message are fictional.
