My explanation must be unclear. I agree with your statement. The issue occurs when the long ago original work subsequently becomes subject to question - and therefore potentially invalidates the new person's work. In itself, yes it is sufficient. But as knowledge upon knowledge grows it will...

Calm down, Steam! It's just an idea - not an attack on you, the scientific community or anyone else. Checking? The same scientific community who currently peer review scientific papers, naturally. "verifiable current scientific 'fact'"? Really? Ok - Those hypotheses that have been shown to...

Thanks, Harry - yes it helps. But I suppose I am looking for more something more rigorous than links between concepts. I'm interested in verifiable hypothesis dependencies - so if someone publishes a paper that, say, derives from other's works, those other works also have to be proven, and so...

I'm asking this question here on a physics forum because a physics question sparked this off. However, it is applicable to all aspects of scientific knowledge. I am looking for a scientific knowledge dependency graph. This is one centralised database which captures the specific and required...

Thanks, chingel. The Wikipedia page lead me to... http://web.archive.org/web/20110719232148/http://www.macalester.edu/~halverson/math36/GPS.pdf which explains it thoroughly.

As far as I understand it... Each satellite transmits a signal that the receiver receives. This signal consists of (at least) a satellite identification together with a time-stamp of when the signal was sent and its position at that time. The receiver calculates the distance from the...

If visible light is part of the EM spectrum just like radio waves, is it possible to construct a radio like antenna (metal pronged structure) to detect them?

Thanks for the reply! I've done some reading since your reply. So, gravitational time dilation occurs because of the acceleration due to the rotating disk (just like gravity causes). Both A and B are accelerating at different rates because of their different positions on the disk. Your answer...

I was just reading about the experimental proof of time dilation using some atomic clocks on aeroplanes. Which got me thinking... Consider a rotating disk. Say it is a few hundred metres radius (although its size makes no difference to this question, it makes it easier for me to visualise)...

Thanks for all the answers - really useful. I'm thinking that gyroscopic forces can explain this as well somehow. But I'm not sure how. Again, intuitively, if there were more than one axis of rotation (and I suppose I could imagine either 1 or 3, anything else would seem arbitrary) how would...

Consider a free floating spacecraft in space sufficiently far from any gravitational or other external forces. The spacecraft is equipped with attitude control thrusters. The thrusters fail and fire randomly and intermittently but symmetrically about the craft's centre of mass i.e. the craft...
