Not that long ago I discovered browsing through the internet this material that I want to introduce to you. It's Vantablack, the blackest substance of all known to man today.
Those of you who are familiar with light and colour theory already know that black is the colour we see in absence of light. The colour of an object is the sensation that is produced by our brain when it interprets the wavelength of light rays reflected by that object and perceived by our eyes. As you know, objects absorb and reflect the light they receive, and depending on which part they reflect and which part they absorb, the colour we perceive of this object will be different. For an object to be black it has to absorb all light (or nearly all) so that no light reflected from that object gets to our eyes.
What makes Vantablack so special is that (according to Wikipedia, here) it absorbs 99.965% of the visible light spectrum. There's no other substance known to man that absorbs more than Vantablack, so we can say that Vantablack is nowadays the blackest black of all known blacks.
Currently, production of this material is being developed for use in aerospace and military industries (the most advanced of them all, of course). The question is if this material will get to be cheap enough so that we can make paints with it. I certainly would love to have some Vantablack in my desk...
Will we see it?
