    Probably becuase they aren't the same. For one, the speed of light is a constant, where time is a variable. And they aren't the same units.

      So you are saying that if Einstein was right we are all getting younger? And time for me is more a constant than a variable. I have difficult to see how the speed of time could change. jhaga CodeProject House, Paul Watson wrote: ...and the roar of John Simmons own personal Nascar in the garage.

                    But... even if it turns out that c is not constant, perhaps it is realted to time, probably by some weird and complex formula, but it won't be equal. The mismatch of units is a dead give-away. That's how I always knew if i had a physics equation wrong... i they units didn't match up, I new I was toast.

                      I think this is sort of a subjective thing. Time, the passage of time, the quantization of time, etc., is based on human perception or our perception of our machines. Conversely, this perception is governed by fundamental laws of time. For example, chemical reactions occur in the femtosecond time frame. If they occured faster or slower, our perception would be faster or slower. To make things more complicated, even simple senses such as temperature involve the measurement of time. Temperature is the partial derivative of heat transfer over time (if I remember that right). We tend to think of temperature in the absolute, but it's a very complicated perception involving the concept of time. Temperature is an excellent example of time being applied in a rate equation, similarly, velocity. However, the other concept of time is in the measure of "nowness" with relation to the future and the past. How do quantify "now"? Even worse, why is there a "now"? Since science has no answers, you might want to inquire of the philosophers: http://www.utm.edu/research/iep/t/time.htm[^] (an excellent resource for a lot of annoying questions about time, both philosophical and scientific, I'd say) Marc Help!

                          great link, I have been analyzing, reading, and discussing all day:rolleyes: I will have to read it later. Your analysis sounds good to me. after talking with a friend of mind I can of like the way he put it. "Relativity has reduced time to a fluctuating event.":-D but since I have you here have you ever read about chaos theory? http://www.duke.edu/~mjd/chaos/chaos.html[^] "...For, without a doubt, one cannot really explore chaos without a computer..." ah more motivation for me, to finish my HAI demo, which I have made some promising progress, btw the past couple of days:jig: I can't wait until I'm finished, I feel pressured too, ah.

                                this is relative ;P if you will be inside the black hole, you will insist upon fact, that the black hole speeds up the time in rest of universe

                                  JoeSox Like for example a black hole is proposed to slow down time. A black hole is not slowing down time. It is only an outside observer's view that time is slowing down the nearer a black hole you come. The chemical reactions in your body will be the same and you will feel the same way as always. Of course, the heavy gravitation can make your head spin. :) jhaga CodeProject House, Paul Watson wrote: ...and the roar of John Simmons own personal Nascar in the garage.

                                    I just made some calculations and got this: E=m*c2 is it right?

                                    Not entirely, as you have clearly only stated it for the case of a body at rest. ;P Lets see it you can do it for a body that is moving relative to your frame of reference. That will of course be the equation further up on the page, where you scribbled down your calcs.

                                      Sorry, but these kinds of calculations I only do in my head. And some moron has probably already written them down. :) jhaga CodeProject House, Paul Watson wrote: ...and the roar of John Simmons own personal Nascar in the garage.

                                        great link, I have been analyzing, reading, and discussing all day:rolleyes: I will have to read it later. Your analysis sounds good to me. after talking with a friend of mind I can of like the way he put it. "Relativity has reduced time to a fluctuating event.":-D but since I have you here have you ever read about chaos theory? http://www.duke.edu/~mjd/chaos/chaos.html[^] "...For, without a doubt, one cannot really explore chaos without a computer..." ah more motivation for me, to finish my HAI demo, which I have made some promising progress, btw the past couple of days:jig: I can't wait until I'm finished, I feel pressured too, ah.

A lot more reasonable than the "butterfly effect" (where a butterfly flapping its wings in South America causes a hurricane in the Atlantic), which is a stupid theory because all systems are dampening (of course the media loves it). Chaos theory is better because it allows for extremes within the confines of a system that normally behaves in expected ways. At least, that's my take on it. But I also think chaos theory is overrated (another media frenzy). Lots of things look like chaos because it's so damn hard to account for all the variables governing the system. Chaos is the scientific term for "magic". Glad you enjoyed the link! I am too. Marc Help! I'm an AI running around in someone's f*cked up universe simulator.
