clocks that were used in that time. From what i understand he explains that times moves slower because the velocity with which the clock is moving is slowed down when in motion.

Does time keep on moving slowerif we use, say a digital clock?

Einstein was referring to Time Dilation. Time dilation would make it possible for a fast moving clock to travel into the future, while aging very little. That is, the clock (and according to relativity, any human travelling with it) shows less elapsed time than stationary clocks. For sufficiently high speed the effect could be dramatic. For example one year of travel might correspond to ten years at home. Indeed, a constant 1g acceleration would permit humans to circumnavigate the known universe (with a radius of some 15 billion light years) in one human lifetime. The space-travellers could return to earth billions of years in the future (provided the Universe hadn't collapsed and our solar system was still around, of course). A scenario based on this idea was presented in the novel Planet of the Apes by Pierre Boulle.

A more likely use of this effect would be to enable humans to travel to nearby stars without spending their entire lives aboard the ship. However, any such use of this effect would require an entirely new method of propulsion. A further problem with relativistic travel is that the interstellar medium would turn into a stream of cosmic rays that would destroy the ship unless stark radiation protection measures were taken.

Current space flight technology has fundamental theoretical limits based on the practical problem that an increasing amount of energy is required for propulsion as a craft approaches the speed of light. The likelihood of collision with small space debris and other particulate material is another practical limitation. As a result, time dilation is not currently a major factor in space travel.

If you would like further explanation of this theory, just let me know.

Remember that the theory is called "relativity". So, the time slowing reference means time slows, relative to someplace else that your velocity is high relative to.

That means that on your speeding ship, the clock (digital, analog, sundial, whatever) seems perfectly normal to you. However, if it could be compared to a clock on the other place, that you are going fast, relative to, then it would be going slower.

It is not a clock phenomena, this theory includes the hypothetical (as yet) situation where you would fly off on a very fast ship and stay at near light speed relative to the earth for long enough and you would come back to earth and find your little brother was a grandpa and you were still a teenager. Your body aging went slower. Time itself passed slower relative to your little brother.

He was refereing to time being relative. As our speed increases the rate time elapses decreases. As we speed up, time goes slower.
This was thought up in the early part of the last century, and was recently proven. Atomic clocks, which are extreemly accurate, have been put on high speed planes. After long travel at an extreemly high rate, they have seen the theory is correct. But keep in mind that this change is very small. Only extreemly high speeds will produce a noticable effect.

B. Amplitude the severe determination, or importance, of a fluctuating fee jointly with an acoustic or electromagnetic signal, amplitude is measured perpendicular to the to the time axis of a time-plot, i.e., frequency, of a sine wave. Amplitude is a level of the intensity, loudness, potential, power, or volume aspect of an illustration. In an electric powered circuit operating on alternating contemporary (ac), amplitude is measured because the Voltage (V) aspect and is expressed as +V and V, reckoning on the course of the present. See also sine wave.

Any clock, even your own heartbeat, will slow down as measured by observers in motion relative to you. It doesn't matter how you measure the 'ticks.' So in that sense it's time itself that is slowed down.

he means the faster your mph in a direction the slower everything else will appear [ex when your in a car going faster then the other lane there cars will seem stopped as if you are going ahead in time]

I think he was referring to time travel....if your increase your velocity....time moves slower, so you could actually travel in time....if you could travel fast enough that is. But really I don't know....it sounded good didn't it?!
