My apologies to ghwellsjr, I badly misinterpreted what was clearly written. Matheinste.

That's odd because surely their spacetime "path lengths," and hence their proper times are equal. Matheinste.

The quote below is from Craig and Smith, Einstein, Relativity and Absolte Simultaneity, page 14. An intereting read if you can overlook the religeous agenda. These are purported to be Lorentz's own words regarding SR and the undecideable choice between the Lorentz and Einstein views of the...

There is alengthy discussion on the subject of the linearity of Lorentz Transforms in Torretti, Relativity and Geometry, Section 3.6, page 71. His general thrust of argument seems to be, although I have not plouged through it all as it it seems very detailed:-- The Lorentz Transformation...

Yes, I see what you mean, the two clocks would need to be in orbit and complete one revolution counter to that of the earth, once per day, so in effect remaining "stationary" for want of a better word, at their different heights while the Earth effectively turned beneath them. Matheinste.

The clocks on Earth are not in relative motion with respect to each other. Matheinste.

With regard to the universe being in a motionless state I assume this means that all entities within it are at spatially at rest with respect to each other. Now is it implicit in the statement that time has somehow ceased to move onwards. If it does not then entities still have a path through...

All I want to see is the logic of how this can be... Science should never be a matter of faith surely. Excuse for not replying in full to your calculations the reason being that although I am an unknowledgeable lover of mathematics I only find the formulae and comncepts of any beauty...

There is no need to look for a cause as there is no effect on the clock even when constantly observed from the frame in which it is at rest. An observer moving relative to the clock has a different worldview and to that observer the cause of the different preceived rate of the clock is his speed...

It is just a consequence of putting in a legitimate?? value, c, (for a massless particle) for velocities into the SR relative velocity formula. Remember the formula returns the value of the velocity of one photon as measured?? from the other photon's point of view. Of course whether or not a...

This thought experiment, as others of its kind, demonstrates a principle. We are not bound to use the same experimental set up in practice to demonstate this principle. Any relevant experiment can be used. Matheinste.

Thanks for your comments. I understand your use of the unwinding tape, but it is flawed in regards to my analogy. Yes when the traveler returns he returns to the same distance away from the stay at home as when he started his journey, that is zero. But I am dealing with cumulative distance...

I was trying to point out that they are analogous, not entirely different, but that clocks record accumulated "time" but rulers do not record accumulated "distances" If rulers kept a record of their travels then the accumulated distances of stay at home and traveller woulrd not be the same...

Yes I would be shocked because it it is not analgous to time dilation. This is how i interpret that particular "diffrerence" between the behaviour of a ruler and a clock, however, I am open to correction. A clock measures and records the accumulated measure along the timelike vectors of the...

This is not a post telling people how to use various terms but just a post to explain the difficulties I find. Perhaps it will help others. I find that the mathematical definition of the spacetime interval describes umambiguously, as of course a mathematical definition should do, what the...
