It's a block to a pion. The path length was up to 80 meters. Therefore, some of the pions were up to 89 meters outside the beryllium target. The photons are emitted by a neutral pion after the pion has left the beryllium target. The speed of both light and pions were measured in a vacuum over path lengths up to 80 meters. ================================================ So you have absolutely no idea where the photon came from. "The timing was done by utilizing the rf structure of the beam." So you have absolutely no idea what time the photon was emitted. c = distance /time = a beautiful somewhere along 80 meters divided by the beautiful rf structure of the beam. What was the beautiful half-life of the beautiful pion, ugly bullshitting drosen?

No, because I haven't read the original article or seen the raw data. They did the timing using the rf structure of the beam. They knew the speed of the pions, the distance of the pion from the target, and the position of the detectors. These are more than enough to determine when the photon was emitted. > > c = distance /time = > a beautiful somewhere along 80 meters divided by the beautiful > rf structure of the beam. They weren't integrating over the entire beam path. They were detecting photons from a specific position on the beam path. They had more than one way to calculate the position of the pion when it emitted. The rf structure would be useful for synchronizing the detectors. The rf structure would be useful determining the time between emission and detection. The time of emission, relative to the time leaving the beryllium target, would be calculated from the position of the pion when it emitted the photon. Directional filters could be used in such an experiment. A tube aimed at a specific part of the beam would tell you exactly where the photon was detected. There is a second way to tell where in the beam the photon was emitted. They had detectors for detecting the charged pions, which would provide another way to determine the position of the pion pulse. They knew where on the beam the photon was emitted (via directional filter), and the where the photon detector (they placed it there), and the time between emission and detection (via rf filter). So they had to ways to determine the time between emission and detection. > > What was the beautiful half-life of the beautiful pion, ugly bullshitting > drosen? Yo' is not only signifying, yo' is dignifying. The half life was not part of this determination of c'. The half life of either pion doesn't enter the calculation. Speed of light is distance photon travels divided by time of travel. If you want to look up the half life of the neutral pion, go ahead. Other people have measured the lifetimes of neutral pions and charged pions. Neither could affect the determination of the speed of light. Sounds like you arbitrarily picked a phrase from that jumble in your head. Lifetime is not relevant. The lifetime isn't used for timing. I guess the word "time" fooled you. Maybe Wilson will make more sense than you, when he responds.

This is mentioned in the following link. http://hyperphysics.phy-astr.gsu.edu/hbase/particles/hadron.html The neutral pion isn't colliding with a slow moving photon of equal mass. The gamma ray has less momentum, and less energy, than the initial pion. A lot of kinetic energy is taken away by the electron and the positron. When that pion decays, the photon moves precisely at a speed c in the laboratory frame. So your billiard ball analogy doesn't work. If the speed of the pion were 0, the speed of the photon would be c. There seems to be no controversy about that. However, the speed of the pion previous to the decay is 0.99975c. The speed of the gamma ray was measured in this experiment to by c'=c. So the final photon is actually going faster than the initial pion. Please explain how come the photon is moving faster than the neutral pion. Also explain why the speed of the photon is exactly c.
