For example: Suppose you are on Earth trying to carry out that torch experiment. You carefully measure the distance between the torch and a mirror, you light the torch, and you time how long it takes for the reflected light to get back to you. You will calculate from this data that you (actually your measuring device) are at rest. Next, you move to Mars and repeat the whole experiment. You will again calculate that your measuring device is at rest even though it is clearly moving at a different velocity than it was on Earth. Consideration of this simple fact is how the entirety of the Theory of Relativity was derived. |

that contradicts what fyron said.

Re: OT: System Clock Loses Hour
I think it may have something to do with the time slowdown.

In this illustration, a red bulb sends a signal to a red mirror. Time goes by, and the bulb/mirror experiment moves to position green. The pulse strikes the green mirror and heads back. More time goes by, and the bulb & mirror move to position blue. The light pulse returns to the bulb at position blue. http://home.comcast.net/~anglewyrm/roundtrip.jpg If it takes a different amount of time on each leg, then we can say that the experiment moved (as illustrated), and the speed of light was the same throughout. And as Narf said, it implies that the speed of light is relative to something other than the bulb&mirror. If it comes back in the same amount of time that it took to go out, then something is amiss. Shouldn't the stars change color sleightly as the earth approaches them, and then as the earth pulls away? If earth's motion about the sun is about 29km/sec, or roughly [edit]0.001%[/edit] speed of light, then there should be a +/-1% red/blue shift in colorbands throughout the year. |

Re: OT: System Clock Loses Hour
The Michelson-Morley experiment was trying to detect wind from the earth passing through aether--the fluid that conducts light waves. It failed to notice any, and is considered proof that there is no aether.
your perceptions of time and distance will conspire to give the same result. I recently read a philosopher's quote, that I'll paraphrase: A theory which claims to be unmeasurable is probably best left unspoken as well. Walter Ritz proposed Emitter Theory that suggested light speed was added to local motion, but that was not observed in binary stars as they orbited each other. The example given is that light from the approaching orbit would appear to be C+orbital speed, and therefore the light would overtake previous light, and our observation would be...strange. (maybe reversed) |

Re: OT: System Clock Loses Hour
Ok so I got sick and tired of manually adjusting the clock every few days so I sent in a customer / tech request to Microsoft asking for help.'

You could measure your speed relative to the earth, or relative to the sun, or relative to the calculated center of the galaxy, or relative to the middle of the local cluster. But light itself always travels a 1.0c relative to the observer. |

Gotta be the time dilation.
