oh yeah, I remember Figure 9, its really intriguing due to, from Barbara's perspective, the distance to Alan appearing to be constant for an extended duration, quite a strange effect. Is there a PF thread which explains this strange effect in more detail?

@ohwilleke by the way sorry I was just wondering about this question

Yeah I have read it, and I've also read the articles by Michael Weiss. I'd like to ask about some of the topics in Weiss's article on the Equivalence Principle Analysis.

yeah that's true, i believe that i have digested the first postulate

so i'm still on my OP, and as Dale brought up the clock hypothesis, I'd like to clarify some things about the Twin Paradox as I think that they might have relevance to my OP such as whether my OP scenario shares some of the intricacies of what makes the Twin Paradox so complex though yeah i...

thanks I see. and by the way the Twin Paradox is an important example of the clock hypothesis, and also, for the perspective of the travelling twin, is it that, when his spaceship is making the turnaround, the ticking rate of the earth-staying twin becomes faster than that of the travelling twin?

nah no worries i'm not thinking about the concept of a "one true" anything at all

oh sorry, i meant that they're planted on the ground beside the track, so relative to the earth's surface

Compared to a synchronized pair of "stationary" clocks that are placed beside the track

So in the model of Special Relativity, an object which is in motion is time-dilated. And let's say that we're trying to measure the kinematic time dilation of a moving clock. So an atomic clock is placed on a dolly on a track and its sped along the track. And due to the curvature of the Earth's...

Right I see. and yeah have there been other types of QG models which are background-independent and which are under the category of "deeper theories" as O'Dowd mentioned? and also I guess that O'Dowd placed LQG under the other category

oh i see, and so speaking of the significance of their detailed causes, i was thinking about certain considerations as described above in #4

hmm i see, and i'm also thinking that the switch to a basic lighthouse-model also comes with some additional parameters, such as: - the direction of the vector of the angular momentum of the pulsar (parallel with the rotational axis) - the angle between the rotational axis and the emission axis...

I was reading this 1977 paper about a method of trying to test the speeds of light by making use of pulsars, in it the author Kenneth Brecher describes a model of a pulsar, and I'm wondering about its accuracy and I'd like to double-check. In the second page, the left column, the upper part, he...

oh, so O'Dowd was saying that one possible path to solving the conundrum is considering deeper quantum theories, and he mentioned string theory as opposed to LQG, but i think that one of the main problems with string theory its that its not background-independent, and so i was asking about...
