Living Light

~0.3 million years ago

Increasingly the evidence suggests that our oldest assumptions about light are incorrect, and it is a living substance.
After breaking through the boundary between atmosphere and light, the swarms attempted to taste the light directly. Their tongues couldn't extend properly--the light pushed them against the parts' sides. The tongue bristles felt no substance.
When our swarm captured the light, it stopped producing its brightness and it pushed against the inside of the swarm. This is consistent with the behavior of prey avoiding predators: concealing itself and attempting escape. As the swarm moved further away from the boundary, the light pushed harder, and its amount shrank as the atmosphere inside the swarm began eating it. Eventually the strength of the light overcame the strength of the swarm seams, forcing open small gaps through which it fled.
In contrast, light is inert by the time it reaches the back of the world where our wall parts eat it. The small bits stick to the parts' tongues without any resistance. We had believed the light was also dead when the atmosphere ate it, but the idea doesn't stand up to close examination. A dead thing can't be eaten twice. Light must be alive when it goes from its world into ours, where the atmosphere hunts it.
