seeing as this deals with the universe etc i decided my first post should be this and in this forum. If time slows as you approch the speed of light and speeds up as you accelerate past it. It reasons that time stands still at the speed of light. BUT according to theories an object in motion will continue to be in motion until acted upon by an outside force. What outside force will make time stand still? on another forum we've decided that time is not an object. if time is not an object. what is it?
Yes at light-speed time will seem to have stopped ( for an outside observer ), and will reverse once past that barrier... I feel that light is not an object, <i>or dimension</i>, either... I think that we could view it as an interaction of temporal waves/particles that move in extra <i> spacial</i> dimentions...The destructive interference of these advancing and retarding waves (created by normal particles) , caused by the two ends of the universe either being open(heat-death?) and closed (big-bang) will thus determine the direction of time...
There's no physics that can describe something accelrating to light speed and beyond, so the anser to the question is no. Time is the rate of change.
Speed of light Isn't the speed of light based on a reference point? What if your reference point is moving? Who's to say that there is any object or place that isn't moving relative to something else? It's not hard to imagine traveling at .8 of the speed of light relative to our sun, but to an observer on another star that is moving away from us at .3 of the speed of light, he will never see it because it's moving faster than the speed of light relative to him. I don't think it's really a barrier other than the fact that in order to push or pull yourself to the speed of light, you need to eject something from your vehicle at an ever higher speed, which isn't possible (not yet). Maybe in 1000 years, someone will figure it out. As for mass distortion at high speeds, I think that's only to an outside observer, not noticable to the person actually traveling that fast. I think we'll find out that, like the sound barrier, it will be possible to break the light barrier. It's just too hard to actually do it with our technology, and the limitations of our bodies. Just a thought. I'm sure someone can prove me wrong, but I like to look at things in a more simple matter. Kevin Hill Hilliard, OH
Re: Speed of light According to special relativity, frames of reference become less and less important velocity-wise as you approach the speed of light. Once you hit the speed of light, frames of reference don't matter any more. You're travelling at exactly the same speed with respect to everything in the universe, even yourself! If you try to figure out how that can be possible, you may end up in a padded room like me. And, trust me, typing in a straight jacket is no easy task.
