Neutral pions are photon sources, emitting two identical ones at the same time when they decay. The decay time for the pions is about 8E-17 seconds, which means that even if the pion is traveling a third of the speed of light (i.e. 1E8 m/s), the travel distance is still only a nanometer. This means that you can reliably locate where a neutral pion is when it has decayed to very good precision, regardless of what speed it was traveling at. Where this helps is that you can create a whole population of neutral pions (by manufacturing them in collisions) of many different speeds, and then watch the two photons that come out from all those pions. 1. You can put a photon detector on either side of the pion, equidistant from the place where the pion decayed (which you recall you know to high precision). Then you can time whether one of the photons arrived before the other. E.g. if the pion was traveling at 1/3 c, and you hypothesized (because it makes sense to do so) that one of the photons was going 4/3 c and the other 2/3 c, then one would take twice as long to arrive at the photon detector as the other, and there would be a measurable gap between their arrival times. The experimental fact is that the photons always arrive at the same time, regardless of the speed of the pions that produced the two photons. 2. You can in fact put two photon detectors on ONE side of a pion machine separated by some fixed distance x, and you can create the pions in tight bunches. Then you can in fact measure the time of flight of the photons emerging, simply by seeing the difference in time between photon pulses in the two detectors T, and then the speed of the photons are directly measured to be x/T. The experimental fact is that the speed of the photons is always c, regardless of how fact the pions are moving. -- Odd Bodkin -- maker of fine toys, tools, tables

It's measured, however, that they may travel far bigger distances; so take your "set of experimental facts" and put it straight into your dumb, fanatic ass, where it belong. Like any other fanatic idiot - you're combining real facts with your delusions and plain lies - into "set of facts". That's all.

Unfortunately, you merely display a serious lack of understanding of
geometry. There is no such thing as a "stationary point in space", the
closest concept is "points at constant values of a specified coordinate
system".
For example, draw Cartesian axes X and Y on a piece of paper, and draw a
dot at X=1,Y=1. Is that dot a "stationary point in space"? -- NO: slide
the paper around on your desk and it is quite clear that the dot is not
"stationary" in any meaningful sense [%], but it is at the same point
relative to the X and Y axes.
[%] You probably think of points in the room as "stationary",
but that is clearly ignoring the motion of the earth -- in
our everyday lives we do that sort of thing all the time, but
in physics it leads to serious errors. You are really thinking
in terms of coordinates relative to the room, without
enumerating those coordinates.
In relativity this is more complicated, as time is included in the
geometry of spacetime. Without coordinates [#] there is no way to relate
spatial points at one time to spatial points at some other time.
[#] or equivalent (which are advanced topics).
In modern physics there are two quite different meanings of
"stationary", neither of which is anywhere close to what you are
attempting to discuss:
1) "stationary relative to a given coordinate system" means at
rest in those coordinates.
2) a "stationary region of a manifold" is one in which there is
a timelike Killing vector throughout the region.
Your entire approach is based on a misunderstanding, and is quite
useless.

Andromeda moved on, but at the moment of observation that straight line existed and traced back to where a star existed at a point in space 2,537,000 years ago. > > Isn’t that point of emission a “stationary point in space� If light moved at the same speed in all directions away from that point, and if we can pinpoint that location because a star in Andromeda was there 2,537,000 years ago, that point cannot be moving. And, if it is NOT moving, doesn't the straight line trace back to a "stationary point in space"? The Big Bang has a straight line that traces back to a "stationary point in space" -- The Starmaker -- To question the unquestionable, ask the unaskable, to think the unthinkable, mention the unmentionable, say the unsayable, and challenge the unchallengeable.

Not one eensy bit right. if there was no force on the moon...the moon would travel in a straight line. That line can be traced back to a "stationary point in space".
