Black Holes are the holy grail when it comes to science fiction and astrophysics. They’re sexy and coy, mysterious and fascinating because they radiate on a spectrum invisible to the human eye. Combined with their destructiveness and it’s too irresistible.
“Black holes are objects with such incredible mass and strong gravitational fields that visible light can’t escape them. Often, astronomers can perceive black holes because they are sucking gas from neighboring stars, and then spitting energy back out in the invisible, super-hot x-ray region of the spectrum. While we understand black holes far better than we did even a decade ago, there is still no conclusive theory that explains why black holes exist or how, exactly, they function.” writes Annalee Newitz at io9.com.
