 List contributors ..
I recommend you read Claude Shannon's papers on Information Theory (circa 1940's .. statistical analysis that reaches the same deductions:  
un-changeable past despite the completeness of past data ...  
and ... the option spaces future which can be enacted~affected, despite incomplete~indefinite data.
An important alternative conceptual frame of reference .. in objective terms rather than interpretive!subjective.

 Hi Doug,
Yes I agree that it is hard to believe unless we make it simpler.  Einstein has made this very complex. :)
Past is memory, Present is observableand Future is a possibility.In this way all three can co-exist as piece of information at different coordinates of space. Past is information which we cannot interact with except to the extent that we can bring it to the present, through some retrieval process.Present is the information that we are currently accessing.Future is the information which cannot be accessed unless conditions are fulfilled to make it present as an outcome of processes of naturally evolving universe.
Keyword here is information, and information needs storage device!!  Infact we need three different kind of storages namely Past, Present and Future.

Hi Tufail, 

    Glad you liked the videos! 

To answer your questions, if the disk and magnet rotate in the opposite direction, the current direction reverses, so it would be negative. If the magnet and disk are reversed in position, the current direction remain the same if the magnetic field direction through the disk remains the same, if the magnet is flipped over, the current reverses. So in every case it obeys the left hand rule for electrons in the disk moving across a stationary magnetic field if you take the Maxwellian stance; current is generated via the Lorentz force. 

Yes, I think I follow on your other point - I am just trying to think of a better example - perhaps the relativistic idea that the past and future co-exist with the present is something impossible to test in principle, since there is currently no known way for an observer to visit the past and prove that it co-exists. I was thinking the other day about the implausibility of the space-time continuum and the big bang theory - if Einstein were right and the future and past co-exist, then immediately after the big bang, as soon as the arrow of time started, all places and events until the end of time would need to be conjured into existence all at once! The entire time-space continuum would need to suddenly "exist" ! I personally find this very hard to believe. : )

Hello Doug,
Thanks for those videos!!
You did an interesting experiment, though I feel, that perhaps all cases are not discussed. 
I wonder if it would be beneficial to discuss those cases.
I wonder what would happen if both magnet and disc are co-rotating but in opposite/ counter clockwise direction. Will it give a negative or positive voltage?.
I wonder what would happen if position of magnet and disc is interchanged and all cases are repeated.
However I would like to clarify when I said that "it cannot be measured",  I mean the absolute impossibility of measuring/ detecting. Not that it is not measurable by using one method but possible to measure by using another method. 
Speed of light (as we observe at present moment/era) is so fundamental to the nature of reality , that without it space-time will cease to evolve and expand, which becomes a motion-less Universe. 
Hence time (which is detected from motion) and space (which is measured only when time is available) are no more detectable, though they may exist as information/knowledge on landscape of all possibilities untill such time Universe chooses to evolve in one way or the other with a particular reality. And landscape of all possibilities is not a physical object.

Hi Tufail,
     Yes, perhaps that is another interpretation...not really relativistic or Lorentzian. But that does lead into the other point that you mention, which is "if anything cannot be measured then it is no more a physical object or phenomenon" - which sound relativistic. I think a Lorentzian view would be that certain phenomenon can't be measured because there are equal and opposite effects occurring at the same time that cancel out. A good example of this is electromagnetic induction with the Faraday unipolar dynamo. I have a couple of videos I produced with an experimental demonstration of the paradox, and in part 2 reach the conclusion that there is experimental evidence to support the notion that electromagnetic induction can occur even when there is no relative motion between the parts. For reference, here are the links to the two YouTube videos: 

Part 1: The Paradox   https://www.youtube.com/watch?v=gduYoT9sMaEPart 2: The solution    https://www.youtube.com/watch?v=c5wgmTGi5pU&t=6s
The point of the exercise is show that what should not exist according to relativity might actually be detectable...

Hello Doug,
Yes, this question had  bothered me. Now it does not bother me anymore. 
Speed of light is the factor  by which space and time are related and separated from each other. In absence of such a factor, space and time cannot be distinguished from each other in this Universe , hence cannot be measured. And if anything cannot be measured then it is no more a physical object or phenomenon. 

To cut the story short: For me space , time and speed of light are equally fundamental. Either they all (physically) exist or all of three(3) vanishes and ceases to exist.

Hi All,    
  I recently have found a couple of relativistic concepts that I have found logically disturbing and thought I would throw them out there. 

The first is Einstein's redefinition of time as "that which a clock measures" which differs in a dramatic way from the more classical definition of time as being "the duration between events" or "the duration of an event". To give an example, if three observers watch a sunrise on earth, then two of them fly in opposite directions around the earth while the third stays put, and meet back at the same place where they then watch the sunset, all three will disagree on the elapsed time for sunrise to sunset using clocks they have carried with them. In other words, according to Einstein, there is no actual constant duration between the sunrise and sunset, even though all witnesses are present in the same velocity frame for the start and finish. Further, the idea that the number of ticks on the clock defines how far you have progressed into the future would also be wrong according to Einstein, since all the clocks would have different ticks even though the share the same present at the start and finish. Why are these contradictions not fatal to Einstein's theory?
The second has to do with the statement 
“indeed that the speed of light is actuallymore fundamental than either time or space” 

-         http://www.exactlywhatistime.com/physics-of-time/relativistic-time/

However, the speed of light depends on both“time” and “space (distance)" = distance/time
Is this not a circular argument – that aphenomenon that depends on time and space is more fundamental than time andspace? 

It is a bit like saying the speed of sound in air is more fundamental than air and time. 

Anyone else bothered by this ??

Hello Hans.
My comment at Vixra on Mass- and Field Deformation:
Dutch scientists play a big roll in theories about Gravitation and the (expanding) universe. Your paper is an interesting approach and may be put in line with these scientists. I agree with the comment of Rodney Savidge: It would be rewarding to include a glossary providing clear definitions of (in effect justifying the use of) the many esoteric terms (e.g., hop landings, modules, etc.). 
Best regards.Ruud Loeffen.
