The principle that “moving clocks run slow” was put forward by Albert Einstein in his theories on Relativity. They are too complicated (a) for me to fully understand and (b) to explain on AB. The theories have been proved (to a degree) by comparing the progress of highly accurate atomic clocks, one travelling on a fast moving aircraft and one remaining stationary on the ground.
The aspect of this I always have difficulty with is that both clocks are moving (relative to the other) so how is it determined which of them is the slow runner ?!?!?!?
There are a number of good web sites which set out to explain this to mere mortals. If you are a simple as I am, however, it will take you a while to get your head round it.
Thanks rojash, but in the example of the two clocks there are two observers: one on the plane observing events on the ground and one on the ground observing events on the plane.
Both could be considered stationary (or moving) with the other moving (or stationary) relative to him. So whose clock runs slow?
I know from the experiement that was undertaken that the clock on the aircraft ran slow. But people in the aircraft could well argue that they are stationary relative to the clock on the ground, and it is the clock on the ground that is moving and should thus run slow.
If you remove the reference points (i.e. the earth and the stars, etc.) both arguments are valid. Both observers could argue that they are moving (or stationary) relative to the other. So whose clock runs slow then?
Ah, JudgeJ, you are having the same problem with relativity that I am, I see! Next week I will ask Dr Steuernagel that very question, and pray I understand enough of the answer to relate to you. In the meantime, perhaps you can gain some insight from an answer from a previous thread, given by Clanad. http://www.theanswerbank.co.uk/Science/Question154541.html
The problem arises when you think of space and time as separate entities. In fact they are bound together in what Einstein called "spacetime". When you are stationary, all your movement is through time. As you accellerate, a proportion of this movement through time is diverted to movement through space. So the faster through space you travel, the less you travel through time. If therefore you could travel at light speed, all of your movent through spacetime would be taken up with your movent through space and there would be none left for your movement through time. Time would then stop for you. Light (photons) do not age because of this. Mad eh?
does anybody know if the two atomic clocks used on the experiment continued to display the time discrepancy indefinately or did they "catch up" at some point( which could indicate that the apparent difference in time was an "illusion" rather than a real change - a bit like the way the "visual position" of an object and the "sound "position eventually catches up when the object stops moving.
Possibly a obvious question thats been dealt with but I don't seem to have been able to find the answer
