Saw this article come by on Facebook the other day from
I Fucking Love Science. It has a video of someone demoing what happens when you shine a laser on a piece of the newest version of Vantablack. The old version supposedly absorbed 99.96% of the light that hit it, and this is claimed to absorb even more, so almost 100%.
I got thinking though, light is after all just a form of energy. So if it's absorbing all this energy, from the laser in the video, or even just from the lights being on and the sun being on,
where is all that energy going?
Granted the energy of sunlight or room lights at any given moment isn't too high (otherwise we'd all be fried!) but if it's absorbing basically ALL of it every second that it's in the light, it's got to be building up pretty quickly.
My brother posited the logical sounding idea that it just re-emits it as infrared or something. My friend put forth the much more exciting (though probably less likely - lol) idea that it's falling through some dimensional rift or something.
As an ancillary question, I was wondering about applications though, if it's such a perfect absorber of energy, would it be a contender for some awesome new battery tech, or incredible breakthrough in solar cells?
