    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. Later,

          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.

              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.

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.

                      Short answer: no. Longer answer: There are two different quantities with the name speed-of-light. The first is a universal constant, c, and is defined to be: 299,792,458 meters/sec (see here). The second quantity is the speed of actual light (that is, photons). Light travels in different speeds in different media (e.g., slower inside water or glass). The constant c happens to be the speed of light in vacuum. Time, on the other hand, is a basic variable. One may think of time as one of the 4 coordinates of space-time (special and genral relativity). It is indeed confusing that one of the coordinates of space time has different units (seconds) from the other three (meters). (To confuse the issue even more, physicists sometimes work in a coordinate system in which the time unit is meters. In that system the constant c is equal to 1.) Did this confuse you even more ;) ? Gil -- Caveat: This is a classical physics description, as opposed to quantum mechanical one. Currently there is no satisfatory theory of quantum gravity.

                          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.

                              Well, the clock you are talking about can't be outside the shuttle. The clock has to move 300000 kmph RELATIVE the shuttle.
