That is correct, as would a speed change. What directly causes a change is relative phase and both path length difference and the speeds of the rays affect that. George

I am not just thinking of my own work here. There are many others who compose computer simulations and animations. I'm suggesting that there needs to be a way of publishing such things, just as there is a way to publish written works in a journal. The publishing industry hasn't caught up with electronic methods. I cannot publish a computer animation in a book. I cannot even publish the source of my programs because there is a lot of code that doesn't show up. I can publish my own code and an .exe file...I can put all my programs on a CD, complete with Vbasic....but I cannot be certain that computers will be able to run that kind of thing in a hundred years. The same applies to Java. I have another program that animates a little invention I have patented. That cannot be included with the patent even though it demonstrates the working principle very efficiently. ...much better than a dozen diagrams. The Patent office hasn't cought up yet, either. The world needs an electronic 'live' publishing system. >>>> I hope brightnes curves, analysed according to teh BaT, will throw some >>>> light >>>> on this whole topic. >>> >>>Not if you consider lab experiments invalid >>>because they are "near a large mass", that >>>would obviously also invalidate your stellar >>>modelling results.

Even 10 years - compare VB6 and .net > The same applies to Java. Less so since it started with a standard whereas Basic always came in many flavours, but you are right, everything moves on. The best format is something that has lots of material that will be of interest. You could try capturing the screen animation into mpeg, films will be around for a very long time and even if mpeg becomes obsolete there will no doubt be converters produced to keep the content available. > I have another program that animates a little invention I have patented. > That > cannot be included with the patent even though it demonstrates the working > principle very efficiently. ...much better than a dozen diagrams.

In that it directly answers the question of the speed of light from a moving source, with the minimum of other factors, yes it is. >>> ..... as will a change in path length >>> difference.. >> >>That is correct, as would a speed change. >>What directly causes a change is relative >>phase and both path length difference and >>the speeds of the rays affect that. > > A small speed change would make no diference. The time to cover any distance is inversely proportional to the speed no matter how small. If the speed was the vector sum of c and v, Sagnac would give a null output. You know that is the result from your own simulation Henri. The only model that fits is if the speed is c in the lab frame for whatever reason. George |
