"I think engineering will supply our demand for a "spiritual" life after meat death."
- Bart Kosko

Black Coating  
  A material that absorbs practically all incident light.  

One good way to be invisible in space is to be non-reflective.

“Well, we have a black coating now that’s ninety-nine percent absorptive, and I don’t need ports or windows. At that, though, one percent reflection would be enough to give me away at a critical time. How’d it be to put a couple of the boys on that job? Have them put a decimal point after the ninety nine and see how many nines they can tack on behind it?”
From Gray Lensman, by E.E. 'Doc' Smith.
Published by Astounding Science Fiction in 1942
