The Milky Way’s Most Mysterious Phenomena: Black Holes

Black holes may be the most mysterious astronomical phenomena. In fact, astronomers only know that they exist because small flashes of hot gas are visible right before they are sucked into the invisible holes.

Black holes are formed when massive stars or supernovas explode, begin to fade, and fall in on themselves. As they shrink, the gravitational pull around them becomes stronger. The pull is so strong that nothing nearby, even light rays, can ever escape the black hole. Scientists also refer to these as regions of spacetime.

The phenomena of black holes was first hypothesized by John Michell and Pierre-Simon Laplace in the 18th century. In the 20th century, scientists Karl Schwarzchid and David Finkelstein also studied them. Ultimately, these researchers concluded that black holes are part of theories of general relativity. Research also indicates that there is a supermassive black hole at the core the Milky Way, our solar system’s galaxy.

Black holes are a strange and complicated scientific phenomena. Though scientists have been researching them for decades, these holes still leave many questions to be answered.
