What is your point? Seriously.
[/quote:5c0a6fe00d]
My point Mr. Gisse is that Einstein's theories make the extraordinary
prediction that clocks in high Earth orbit (such as those on the GPS)
will run FAST, whereas clocks in low Earth orbit (e.g. on the ISS)
will run SLOW. This latter prediction has never been confirmed,
and nor do i believe that it ever will be, 'cos i don't believe for one
microsecond that it happens eh!

Why don't i think it happens ?

Firstly because Einstein's derivation of SR time dilations is daft!
He assumes the impossible (i.e. that the speed of light relative
to an observer is independent of the speed of the observer). Then
he shows that indeed it is impossible UNLESS moving clocks go
slow, and he concludes that therefore moving clocks DO run slow.
Well as King Canute discovered: Time and tide wait for no man eh!.

Secondly if clocks in low Earth orbit really do go slow by the
relatively large (i.e. easily measurable) amounts predicted by Einstein,
then someone would have demonstrated this long before now, i think.

[quote:5c0a6fe00d]Why are you so fixated on putting a clock on the ISS? If you want to
see the verification of SR's predictions go play with GPS.
[/quote:5c0a6fe00d]

The reason i particularly want to see the test done on the ISS is
that the test i am advocating is far more reliable and accurate than any
inferences from the GPS. It is not easy to accurately compare clocks
which are 20,000 km apart and travelling relative to each other at
several km/sec, whereas clocks which are adjacent and stationary
relative to each other can be compared very reliably and accurately eh!

[quote:5c0a6fe00d]GPS is calibrated with both SR *and* GR. Time shift due to curved
space and velocity, without one of them you will be off - it does not
matter which one you pick.

Well if clocks in both high and low earth orbit really do behave in the
extraordinary manner predicted by Einstein's theories, then, seriously
I'm a relativist eh!

Golly! Silly Albert. Good thing you're on the ball or he might have
pulled a fast one on us!

Well don't expect anyone to drop their devotion to Einstein just because
i point out that SR is daft, Mr. Powers, but an experiment to determine
the time dilations on a low Earth orbit satellite would put an end to this
deception:

"If one of two synchronous clocks at A is move
in a closed curve with constant velocity until
it returns to A, the journey lasting t seconds,
then by the clock which has remained at rest the
travelled clock on its arrival at A will be
1/2 * t * v^2 / c^2 second slow." A.Einstein (1905)

Unless "Silly Albert" is right of course !

Why start another thread? Are you tired of this one?
