Black holes, complex and difficult to understand, have intrigued both scientists and physicists alike since the eighteenth century. French scientist Pierre-Simon Laplace, born in 1749, was one of the first scientists to argue for the existence of an unexplainable body that encompasses an endless amount of space . Following Laplace, John Archibald Wheeler, an American physicist born in 1911, coined the term “black hole” for a space entity that is “so compact (in other words, has enough mass in a small enough volume) that its gravitational force is strong enough to prevent light” and all other matter from fleeing its body (What Is a Black Hole?). Black holes, therefore, are masses that have a gravitational force so great that they attract all substances that surround them, even waves of light, thus trapping the material within itself.

Though cannot be directly seen, black holes can be detected through the use of electromagnetic radiation. As gases approach black holes, they are caught in the gravitational pull of the mass; therefore they begin to orbit around them. The movement of the gas particles around the black holes creates friction, causing frictional heat. This heat will then emit a range of “X-rays and radio waves,” which are detectable by Earth telescopes (What Instruments Do Astronomers Use to Find Black Holes?). And so, with the use of radiation, the…
