Well no. First off- the experiments have suggested that LS varies in different directions but, like ALL scientific theories, it will never be classified as being 'confirmed'. There IS compelling evidence for LS variations in different directions though Very Happy. Sorry, shouldn't play so much with semantics I know *shakes head sadly*.


I was using 'confirmed' in the sense that the experiments had been repeated with the same results sufficiently often that it would convince other scientists that LS was variable in different directions.

Anyway, back to the point. Relativity WORKS- so there is NO reason to through it out yet.


We haven't thrown out Newtonian mechanics. It works too for the tasks its used for. Clearly Relativity will occupy a similar position. Besides, I thought that Relativity was recognised to be an interim model along with quantuma mechanics until something comes along that encompasses both.

The variation of LS is only 400m/s in different directions which is VERY small when you compare it with the 299,792,458m/s that is the generally accepted value of LS. All this suggests is that light should NOT be used as the ULTIMATE frame of reference("FoR"), but an arbitary value could be assigned to a new frame of reference- say... 300,000,000m/s? Eitherway, there is an alternative theory of relativity that seems to produce the same results and also takes into account the variations in light speed. In this theory (which I personally distrust- I'm a determinist by nature) instead of using light, it uses SPACE itself as the "FoR". In a way, it has reawakened the good ol' days of the lumniferious aeyther and has space as not an absence of matter, but as a strange quantum foam lattice that flows (hence the change in LS).


400 m/s difference is significant if the experimental error is only +- 25 m/s say. While if the experimental error is in excess of +- 400m/s why are we having this conversation?

As to quantum foam (can you shave with it being the most important question to mankind?) why does it prohibit determinism?

Yes, the metre in terms of LS is defunct, but the platinum rod, kept at a steady 24 degrees Celcius in France, remains the same size. Thank god for those dastedly frence Razz (with apologies to the frence types who read this).


Isn't there a fundamental unit of distance? Why not define the metre in terms of that?

Quote:


Actually the electric and magnetic permitivity constants CALCULATED LS, not the other way round. Sure they might need to be tweaked a bit- maybe add a small error to them. Say about 0.00013% or so? Nothing really that big considering everyone automatically rounds off at 3 significant figures Razz. MAN that's a lotta writing. I'ma gonna go sleep now Confused


Vague memories returning: IIRC, weren't those constants defined to be particular values for a vacuum, hence giving rise to constant LS? Hence, if you want them to fluctuate doesn't that require the underlying nature of a vacuum to fluctuate too?

Finally, perhaps you can answer a quetsion for me. Does energy have inertia?
