Scientists have come up with a substance which is 30 times darker than the standard benchmark of "black" used by the  U.S. National Institute of Standards and Technology.

Huh?, you say.

Black, as we all know, is the absence of colors.  Things that are black are black because they absorb all colors of light and reflect none of those colors.

Trouble is, there isn’t actually anything known that absorbs all the spectrums of light and reflects none (what is known as "ideal black").  Black paint, for example, has a reflective index of 5 percent to 10 percent.

By comprison, this new substance — which is really really black — has a reflecting index of 0.1%.

Practical uses?  You betcha.  Because the substance catches much more light than other "black" things, it works better as a solar panel.

This of course leads me to ask, "How much more black can things get?" 

And the answer is "None.  None more black."
