carbon nanotubes, creating black that absorbs all light, step closer to quantum knowledge of black hole?

black is defined as reflecting the least amount of light since it absorbs so much, our eyes that capture light on a different wavelength to determine our universes colors views more light absorbing pigments as black. So why cant we create a black that absorbs all color. And by creating a substance that can absorb all light, would that further increase our knolwedge of a black hole. The theory is that a black hole’s gravity is so strong it pulls in the light not absorbs, but thats just a theory….. maybe the color has something to do with the gravity?
Black holes absorb all light and do not reflect any light, Nanotubes reflect .045 percent of light, which is the darkest material on the planet. why cant we make a material that absorbs 100% light. like a black hole.
Ivan A, All objects have gravity, even an atom, maybe I am asking a question that cannot be answered yet because we haven’t figured out what a graviton is yet. On a quantum level the photons are being pulled into black. If you haven’t noticed yet, all energy is just a different form of the same thing.
even gravity


  1. I’m fairly familiar with carbon nanotubes (especially in experiments) and I don’t see why they have anything to do with black holes.
    You have a very large misconception of light absorption and black holes. The “black” in black holes is an allegory of the celestial object we call a black hole.
    Color, the way the human eye or our instruments perceive it and detect it, has NOTHING to do with gravity.
    Edit: My answer is based on 15+ years of being involved in physics and research; if you think you know better, you go ahead and publish your findings.

  2. “….it pulls in the light not absorbs, but thats just a theory…”
    What do you think a theory is? It is not like some crackpot scientist thought of this in his free time. It is a theory that has been tested over and over again with mathematical rigor. It has withstood countless tests of peer review.
    So, black hole theory is pretty solid. And it has nothing to do with anything being black. Go read up some wikis about black holes.

  3. Yes, black holes absorb light. And you can make things (perhaps nanotubes, though another example is ‘gold black’) that absorb light. But the mechanisms with which they absorb light are completely different and entirely unrelated. You will learn nothing of one from studying the other. And they are both pretty well understood at the level you could study them using your idea. One works by coupling to the electromagnetic wave, and then allowing other excitations in the substrate. The other works by creating gravitational curvature so great that space-time forms a singularity. These are completely unrelated.
    As a physicist who works with light, I can tell you that I find this proposed research uninteresting and unlikely to produce results. If you want to study things (nanotubes) that absorb light to make a better light absorbed, great. If you want to study black holes, great. Those are both valid research projects. But studying one to gain insight on the other will lead no where.
    And no, you aren’t asking a question that can not yet be answered.

  4. A black hole and a bunch of nanotubes are totally different objects, working on totally different principles.
    A black hole’s event horizon would capture light by making it travel an infinite distance along the infinitely stretched fabric of space.
    A bunch of carbon nanotubes, on the other hand, would reflect light on their many surfaces until most light is absorbed–have you, by any chance, ever seen powdered metal? Powdered nickel, for instance, is coal black, yet when made into a continuous object, will shine like a brand new coin.
    But get this: for the light that it absorbs, the pile of carbon nanotubes will get warmer and will start emitting infrared–actually at room temperature it should already emit some infra red. Subject it to enough energy and it will radiate in the visible, becoming red-hot, and eventually white-hot.
    Actually, you can also look at the filament in an ordinary incandescent light-bulb: the tungsten filament is quite dark, but heat it by passing electricity in it, and it will emit visible light.
    Search a bit about “black body radiation”, and you will see what this is all about.
