since nitro recently posted in another thread that there will be a tv show about brian greene's "the elegant universe", i started reading the book again. i think chapter 2 alone is worth buying the book. it deals with motion and time, which is what i'm about to discuss. anyway, as stated in the book, einstein said that all objects in the universe are always traveling through spacetime at the speed of light. the speed of an object through space is also how much of its motion is diverted through time. so, the more speed an object has towards the speed of light, the less motion there is for the passage of time; so time slows. as humans on earth, since we are not moving through space close to the speed of light, most of our motion is through time, not space. when an object uses all of its motion through space, there is no motion left for time. so at the speed of light, there IS NO PASSAGE OF TIME. now here is the point of my thread: what the hell are the consequences of the concept that at the speed of light, there is no time? what the hell does it mean to say there IS NO PASSAGE OF TIME AT THE SPEED OF LIGHT?! what i mean by that is: if you were alive and moving through space at 99.9% the speed of light, how would that be different than being alive and moving through space at 100% the speed of light? what would it be like to exist moving through space at 100% the speed of light and NO PASSAGE OF TIME?
