Phenomenon: In anomalous dispersion gases, Light Group Velocities travel faster than the speed of light.
Description: During atomic-electron absorbed photon, atomic collided with other particle, the absorbed photon will find a more suitable exit in its original direction of movement.
Explanation: Photon was absorbed by electron and then into Hyperspace (Time can be ignored). Since the entrance been interfered, the exit (similar to the entrance status) had emerged in the photon's original direction. Because without spending time in that dimension, Superluminal phenomenon occurred while Photon returned to the material world (actually, the speed of light is constant). [Fig. illustration for the changing of electron spin angular momentum.]
