Good Grief man! I glad you posted that last link. I was begining to think I would have to take him seriously. The mind that would revel in such basic ridicule is not a mind to be trusted.
I found this staement on his previous page of signal interest.
"They flew atomic clocks on commercial airliners around the world in both directions, and compared the time elapsed on the airborne clocks with the time elapsed on an earthbound clock (USNO). Their eastbound clock lost 59 ns on the USNO clock; their westbound clock gained 273 ns; these agree with GR predictions to well within their experimental resolution and uncertainties (which total about 25 ns)."
I think this above contribution by Baez justifies skeptical reception of much so called scientific proof by honest enquirers.
Let us assume that these flites were both non stop global circuits (which they very likely were not).
Let us assume that the East bound clock did in fact loose 59ns. and let us assume that there was neither head wind nor tail wind(since no data is cited) Let us further assume that the flight took place at near enough to zero latitude and that the airspeed hence ground speed was 500km/hour.
Further, let us assume an equatorial circumference for the Earth of 42,000km and this figure including the increased circumpherence due to the flight altitude.
So after a flight time of 80 hours our east bound clock will have travelled the 40,000 km circuit required to bring it back to its point of origen.
And so after 3 1/3 days it has lost 59ns.
Now what about the west bound clock? The aircraft carrying this second cloch also has an air speed of 500km/h, hence a ground speed the same.
But because the second clock is being flown in a direction 180d opposed to the point of origen, the overall flight time will be shorter than it was for the East bound clock. therefore any hypothetical time dilation will be of lesser extent than for the east bound flight. Since 'sence' is missing from the GR equations, if this test had indeed agreed with the theory of GR, the west bound clock would surely have lost some time, but not as much as the 59ns lost by the east bound clock.
You see this so called experiment has introduced direction into the arguement, such that the best match to it would be that if a space ship travelled to aCentauri, on board time would be compressed, but on the return flight, time would be stretched back again, but by a greater amount.
;that is if aCentauri lies to our east??
That is where the data supplied by Baez leads us. But don't worry, you can go as far as you like at light speed, just don't think of comming back!
So the data supplied taken at face value, suggests that a space craft travelling east, then returning would actually return before it left................I think not!
Maybe time dilation only exists on planets?? after all, east and west have no meaning in space.
I remain very much unconvinced of time dilation not only by the appauling lack of statistically compelling data, but also by the tawdry attitude presented by one of its cheif appologists as shown by the link you supplied Alex.
cheers,
