Thanks for your help! :)

Hey there I would just like some help in rearranging the formula: [tex] z=\frac{1+\frac{v\cos \theta}{c}}{\sqrt{1-\frac{v^2}{c^2}}}-1 [\tex] for v. Thanks, PP

I am simply looking for the formula to work out the time dilation on cylinders with uniform density. Also, any links to arbitrary precision calculators would be appreciated.

Wikipedia refers to it as the Carroll paradox. It is included in Micheal Clark's book Paradoxes from A to Z as the Paradox of Inference. Thus I get the idea that the story was paradoxical.

I don't understand what makes this story paradoxical. Can anyone enlighten me as to where there is a contradiction or otherwise?

It was not those photons that I was concerned about; just the ones with the interference pattern on the screen. Perhaps I should use a less ambiguous scenario: Now imagine a small sampling of Cesium-134 (134Cs) floating around in space, one light-year away. With a very powerful telescope, one...

So what ramifications does Quantum Mechanics have on this discussion? Wave-function collapse must happen before our eyes catch the affiliated photons. Since we are always looking into the past, does this mean that we can also change it? For example, imagine the double-slit experiment set up one...

I'm sorry to be the one to introduce a time-travel paradox into this thread, but I think that the Bootstrap Paradox ties in well with this discussion; "relating to the existence of information and objects not created at any specific instant of time but instead traveling in a time loop." These...
