U.S. researchers have made the darkest material on Earth, a substance so black it absorbs more than 99.9 percent of light. Made from tiny tubes of carbon standing on end, this material is almost 30 times darker than a carbon substance used by the U.S. National Institute of Standards and Technology as the current benchmark of blackness.

The substance has a total reflective index of 0.045 percent — which is more than three times darker than the nickel-phosphorous alloy that now holds the record as the world’s darkest material. Basic black paint, by comparison, has a reflective index of 5 percent to 10 percent.

They’re already talking about the benefits of using this, or a similar material, in future solar panel construction, as it would be incredibly efficient at absorbing nearly all the light that hit it.
