Faster than light
shvarz:
OK....
But why are you telling me this? I never argued with this.
Zelos:
just got the picture you did

This may just be me being out of touch but I haven't actually seen any incontravertable proof that the speed of light actually is the same for all observers in inertial systems.
Do you have any links to actual experiments in which this has been observed? (particularly before Einstein came up with the theory)
I don't actually know of any but as I said, this could just be me being out of touch with physics research papers.
I know they did some experiment with an atomic clock on a fast airplane that circumnavigated the world. while its twin stayed behind. The claim was that they read different times afterwards but if they did then it kind of screws up the explanation given for the twins paradox.
More than likely, the acceleration, different air pressure, magnetic fields or whatever, messed with the workings of the clock on the plane so that it didn't keep accurate time during the trip.
:D PY :D

I do know that mercury's observed orbit was off from its newtonian orbit, and that relativity helped explain it just about perfectly.
There was another thing too, another celestial event, that occurred just a bit after Einstein released his theory but I don't remember what it was.

In the same website: http://www.phys.vt.edu/~takeuchi/relativit.../section07.html
he is talking about Michelson-Morley experiment. I am not a physicist, so I can't tell the details and setup and validity. I just assume that scientists who did this knew what they were doing. I also assume that many similar experiments have been performed many times after the theory has been put forward. Or at the very least that many experiements relied on the fact that speed of light is constant for all inertial observers and got the expected results.
