Top 10 Most Extreme Substances Known on Earth

Here is a nice top 10 list of awesome Earthly substances, ranging form super-hot to the most darkest and the most magnetic to the super-fluid. So without any further adieu

10. The Darkest Substance Known to Man

What do you get when you stack carbon nanotubes on their ends and sandwich them together? A material that absorbs 99.9% of the light that touches it. The microscopic surface of the material is rough and uneven, which breaks up the light and makes it a poor reflector. Then add to that carbon nanotubes act as superconductors in certain arrangements, which makes them excellent light absorbers, and you have a perfect storm of black. Scientists are really excited about the potential applications of the substance; since virtually no light is “wasted”, it would be used to improve optical tools like telescopes, and even be used to make nearly 100% efficient solar collectors.
