Black Holes
Within our galaxy alone, there are millions upon millions of stars. Within our universe, there are millions upon millions of galaxies. Humans have known the existence of stars since they have had eyes. Although interpretations may have differed on what they were, they were always thought of as white glowing specks in the sky, but the mystery does not lie within what we can see, but what we can not see. There are billions of stars lighting the darkness of our universe, but the question lies in what happens when one of these enormous lamps burns out. Upon many speculations, one of the most fascinating is the black hole theory. Not any star can become a Black Hole. For instance, the possibility of our sun becoming a black hole is highly unlikely, simply because it is too small. Only a very large star has the potential to become a black hole. The definitions of black boles are somewhat skeptical. Generally, a black hole is an area of super-concentrated mass. So concentrated, that no object can escape its gravitational pull. In other words, once you get caught by it's gravitational pull, you aren't getting out again. The velocity you n
Black holes do not live forever, and as stars, they die. Speculation on their deaths is extremely speculative. The theory of black hole evaporation seems to be a popular theory on how black holes die. Black holes emit radiation, and the energy to emit this radiation comes from the black hole's mass, thus shrinking the black hole. Gradually, a black hole wears itself out into nothing. Stephen Hawkings presented this idea in the 1970's which was a great contribution to physics. Even though a black hole's gravitational pull is enormous, it does have its boundary. This boundary is called the "event horizon". This event horizon is the point where the black hole's gravitational pull begins. Once you cross the event horizon, there is no turning back. As stated before, the escape velocity of a black hole exceeds the speed of light, and since going faster than the speed of light is impossible, so is escaping a black hole's gravitational pull. Evidence that black holes are real does exist. Even though you cannot see a black hole, as light cannot escape it, you can measure how much mass there is in an area. And if you have a large
