Granted, it might not seem like such a big deal when astronomers find some of the missing mass in the universe, since there's very little that isn't missing. Roughly 95 percent of the cosmos is either dark matter or dark energy. About five percent of the universe is made up of the normal mass we're familiar with—baryonic matter. Yet by adding up the known stars and galaxies and gas, astronomers have only accounted for about half of that five percent.

The title of the paper might not jump out at the average science fan—“Search for Axionlike Particles Using a Variable-Baseline Photon-Regeneration Technique”—but the big idea behind the research certainly should. Physicists at Fermilab have designed an experiment to look for the particles that may make up dark matter—the elusive material that may make up most of the matter in the universe.

Scientists at Rice University and RPI have created a thin, nanotube-laden coating that they say is the darkest material ever made by man. Radiation essentially gets lost in a miniature wilderness of carbon nanotubes that lets light in, then traps it. The coating absorbs 99.9 percent of incoming light; the previous best measured around 99.84 percent.
