You might think you know black... But you don't know Black. Vantablack took the world by storm when it was shown to be the most light absorbent material ever created. It absorbs 99.96% of light, and was recently used by BMW to advertise a Vantablack covered SUV using nanotechnology to adhere the substance to the car. 

But MIT was not to be outdone, and created the darkest substance ever found, though their feat was unintentional. Now they have put their discovery on display, in one of the most incredible exhibits possible.
