A negative space is the space around and between the real object. It is the space that forms around the subject after it has altered to give an artistic feel. A dark energy is hypothesized to infuse all of space accelerating the expansion of the universe. It is also an unknown form of energy. A black hole exhibits a strong gravitational pull that no astronomical object can escape from it. A dark matter is a black space in the universe that constitutes most of the unknown. They so not emit light at any wavelength. The answer is letter D.
