I was unable to view nwr links, appears I needed at least upgrade to xp to view. However looking at your garage too me it appears the transmitted pulse of light has left the garage however is the returning incident pulse that is returning to the garage at 300 times reduced speed.
It appears that the light has left the garage but when the returning part of the light wave starts returning its returning in the unamplified state (300 times less speed or 1 fifteeth of the amplified waves) that were initially transmitting outward.
Has light left the garage but then runs into resistance then after 60 *ns* loses its amplification and only then is the incident pulse able to return to the garage.
"If so" then starlight pulse width could be unwinding as it leaves our solar system (solar garage) less to compress the light wave outside the solar garage thus increasing lights speed. However recompressing once it re-enters our solar system (solar garage).
If lights waves are compressed (resistance to light within the solar garages) then light waves should naturally uncompress once star light leaves the solar garages).
Group velocities temporarily seem to be increasing the pulse wave width by force which makes it appear to be leaving the garage before its reaches the garage. Yet in space ***is**** the lack of solar resistance allowing light waves to elongate (increasing lights speed) without a loss in information when it recompresses (expressed as starlight) upon re-entering our solar system?
***article two pulses (the pulse leaving the garage and the secondary pulse returning.)
The meaning of a negative group velocity is illustrated in figure 2. Within the cell, the peak of the pulse travels backwards relative to the direction it is moving in outside the cell. Long before the incident light pulse reaches the cell, two peaks appear at the far end: one travelling away from the cell at c, the other travelling back towards the entrance. This second pulse travels 300 times more slowly and is timed to meet up with the incident peak. The transmitted pulse travelling at c appears to leave the cell some 60 ns before the incident pulse arrives, enough time for it to travel an additional 20 metres.
