They were opaque to every wavelength of light I threw at them. Visible, infrared, ultraviolet, x-ray, microwaves…I even put a few Astrophage in a radiation-containment vessel and exposed it to the gamma rays emitted by Cesium-137 (this lab has everything). I called it the “Bruce Banner Test.” Felt good about that name. Anyway, even gamma couldn’t penetrate the little bastards. Which is like shooting a .50-caliber round at a sheet of paper and having it bounce off. It just doesn’t make any sense.
Electromagnetic spectrum.
