does a clock actually move slower when travelling close to the speed of light?

Think of distance as time it takes to get somewhere rather than a measurement...The faster you move the more space you squeeze into that distance/time and therefore you slow down time. When you accelerate you are basically squeezing more space within that time. Everything is time, even mass. Mass is created by the slowing down of time itself. When you speed up, because you are squeezing more space within time, you are reducing the size of the universe, and when you slow down the universe expands and therefore time speeds up. Thats it in brief...Oh your answer is yes it does.

If the hands are rotating in the direction that is perpendicular to the to the direction that whole clock is traveling in, then yes, the hands must be rotating slower all the way around. If you agree that 'theoretical time' slows down, then that means that it must take longer for the hand to go all the way around the clock, which implies that it must be moving slower (since the hand has to travel the same distance, yet it takes a longer time to do so).

The other way to see that this is true is to consider what would happen if the clock (the whole clock) was traveling at a speed just below the speed of light. Now what happens when the hands rotate? The total velocity of the clock hand would be the speed of the clock (which I'm assuming is just about the speed of light) plus some additional speed of the hand. If the hand didn't spin slower, then the clock hand itself would be traveling faster than the speed of light. Since the hand can't go faster than the speed of light, it must be moving slower than it would at rest (in fact, if the clock really was going that fast, the clock hand would almost stop).

However, if the clock hand was rotating 'with' the direction that the whole clock was traveling, then you get a fairly complicated situation. The reason being because the speed of the hand will change in a non-linear way as it rotates into and then away from the direction of travel (because the total speed isn't a simple addition of the rotating speed and traveling speed). Not only that, but there would be a length contraction of the path that the hands travel on, so the distances traveled would be altered as well as the actual speeds. Weird stuff.

I'm not sure what you mean be color being relative; do you mean our individual interpretation of color, or the wavelength of light itself? Our interpretations are probably not all identical, so I would assume they're relative (although nobody can really prove this). As for the wavelength of light itself, then yes, there's something called the Doppler effect (for light), which is a change in the color of an object, based on it's velocity relative to an observer 'at rest'.

ABSOLUTELY! A clock in a moving frame really does tick slower. This has been shown experimentally. Muons are created in the upper atmosphere of earth, when high energy particles hit air moluecules. The Muons have a very short lifetime. It should be impossible for any to last long enough to reach earth from the top of the atmosphere. However, muons can be detected at the earth's surface. They make it to the earth's surface because they are traveling at relativistic speeds and experience time dilation.

There is a famous problem called the "Light Clock"( check out http://galileoandeinstein.physics.virginia.edu/lec... that beautifully demonstrates that time passes slower in a moving reference frame. This happens because the speed of light is the same in all reference frames.

The basic idea is like this: You could arrange to send a pulse of light to a mirror, have that pulse be reflected by the mirror, and then sent back to a detector right next to the spot where it was emitted. If this setup is moving relative to you, then the path the light takes is longer, so the round trip time is longer. The website I linked to explains this.

Anything in the frame of the light clock could be timed in terms of how many "ticks" of the light clock happened between two events, so indeed, time does move slower in a moving reference frame.

Colour is relative, 100%.

As to time, theoretical does slow down as you approach c. The mechanical movement of a clock would depend on what type of clock you would think. If it is crystal oscillator controlled, then it goes off of a resonant frequency of the crystal itself, which shouldnt be effected by speed no matter how great. Only relationship I think of between the two is that electrons are what is exciting the crystal and they move at the speed of light, but I dont see how that would make a difference.

i do no longer comprehend that the two. an uncomplicated yet quite over-complicated-stress-men-like-Newton-... by utilising the call of the twin Paradox tries to describe it, it says: Supose there are 2 twins, person who's sent away on a rapid spaceship for 80 years. They vidoechat by utilising skill of Skype and the twin in the worldwide finds that his brother is shifting and speaking far greater slowly then him. the subject isn't because of the fact Skype is defective, it fairly is because of the fact the gap twin is shifting swifter than the earth twin. properly, the earth twin feels that 80 years have long exceeded by utilising however the brother feels that basically 40 years have long exceeded by utilising. what's going to the twins appear as if while they meet? Einstien tried this expirement in an easier way, as I actual have heard from my G4 arithmetic instructor: Einstien made a super guess on the main proper scientists of the day that he ought to actual make time bypass swifter for the main precise clock ever by utilising vacationing at severe velocity in the quickest airplane on the time!!! He extra 2 of the worldwide's maximum precise clocks. He gave one on the floor to work out the outcomes, and the different exchange into thinking approximately him to sluggish its time by utilising vacationing in the airplane. (flies away, scientists wait nervously...) and particular adequate, Einstien back and the clocks had a delicate distinction!!!!!!! subsequently, lots of those men boke because of the fact of repeated experimenting, Einstien grew to become the M.McMahon of his day whilst he left the worldwide with between the main maddening paradox.

I don't know. Einstein's theory on how the speed of light is related to the passage of time has never made sense to me. Of course, I'm not a genius.

I've always thought of time as an independent energy flow, and we only use the travel of light as an indirect measure of it, because we have no means of directly measuring the phenomenon we describe as time.

while a clock mighht, and all the theories surrounding this have yet to be proved in any way, time doesn't. it's a universal constant, like the speed of light.

Yes

no... i dont think so.
