I crashed my Puter Friday night so I'm screwed for about a week. So in my idle time I got to thinkin: SUPPOSE WE COULD TRAVEL FASTER THAN THE SPEED OF LIGHT, WON'T IT BE DARK WHEN WE GET THERE? HMMM? .
No, Cause soon after you arrived there, the light would catch up. But, while traveling faster than light, it might be dark, depending on where the source of light is coming from. If traveling in the Universe, light is coming at you from all directions, so you are really only "outrunning" light that is directly behind you. You will still see light from the sides and from in front of you. But, if you are talking about traveling in a vaccum, or in a sheilded tunnel that was about a billion, billion miles long, then if you travel faster than light and the source is behind you, it would be dark when you got there. And, even if you outran light so fast and sa far, that you were millions and millions of miles away, it would still only take a few seconds to catch up with you. Think about it, light travels 186,000 miles per second. You could be 11,160,000 miles ahead of light, and it would still catch up to you in 1 minute! FedUp2003
Well, Butch, you have to take into account that the light has had a head start on you, of anywhere from 6,000 to 18 billion years, depending on which creation theory you favor. But then again, you didn't say HOW MUCH faster than the speed of light. ???
Obviously, since it manifest itself as the recession of light, the speed of dark is the same as the speed of light, about 186,000 miles/sec.
OK. Here is another question. If you were in a car that was traveling at the speed of light and you turned on the head lights, would they do anything?
The headlights would actually light up, but the lightbeam would not project out in front of the car, but just stay right there in the headlights. It would be dark in front of you, assuming there were no other light sources around. But, once you came to a stop, you would then see the lightbeam project out in front of the car and off into the distance. FedUp2003
But here's one that I haven't been able to figure out: What if you are in a car and you are going in reverse at the speed of light, or maybe speed of light plus a couple more! Once you turn on the headlights, would the lightbeam never travel any further than the point at which the lights first got turned on, and you would only have a lightbeam stretching from that initial point backwards to your car, as you continue to travel backwards at the speed of light...? Or would the lightbeam go ahead and travel outwards through space, at the speed of light, as well stretch backwards to your carlights (that is going backwards at the speed of light) And what happens, to the viewer in the car .. because in the 2nd scenerio, the driver would see the lightbeam as effectively traveling at twice the speed of light ... so what would the light look like? Would it still appear as a normal light beam? Or appear thinned out, stretched, or be in a whole new form/have different properties .... like H2O can be water, ice, or vapor .... Hmmmm... anyone know? FedUp2003
Lets say there is a stationary observer looking at the car. In the case of a car going backwards at the speed of light, the mythical stationary observer would see the car traveling backwards at the speed of light. Lets say the stationary observer sees a car traveling backwards at 90% the speed of light. He would see the light from the head lights going at 10% the speed on thing in the opposite direction. In the special case (limit) that the car approaches 100% L, the light would never leave the head lights. The redshift would be incredible. The mass of the car would approach infinity. The car would become infinitesimally short. http://www.plunks.free-online.co.uk http://www.questia.com/PM.qst?action=openPageViewer&docId=6814120 http://www2.slac.stanford.edu/vvc/theory/relativity.html
This thread reminds me of a dope smokin' circle from high school. NOT that I ever participated....I don't know a damn thing about what y'all are talking about!
Re: Re: Brain Fart -> I don't think they did. But wasn't he faster than a speeding bullet? At what speed does a speeding bullet travel?
Re: Re: Brain Fart -> Speed of a bullet 600 - 5000 feet per second http://hypertextbook.com/facts/1999/MariaPereyra.shtml
Re: Re: Brain Fart -> I thought superman went faster than the speed of light because he turned back time. Of course that was just a movie.
Duuuuudde! It wouldn't be dark [puff-puff], 'cause there would already be the light that got there... [cough-cough] before you did, Man! Smitty Interest on this comment does not accrue until November, 2005... with approved credit.
