Black Hole Misconceptions

There are many older movies based upon black hole misconceptions and beliefs. Just recently I was browsing the internet and came across a great deal of information upon them and thought it interesting! Two of the largest misconceptions are that black holes are cosmic vacumm forces of death and that they contain worm holes to outer reaches of space. This, while very entertaining, is sadly untrue. Black holes are simply stars that have undergone a supernova (death of a star) and essentially, implode. While it does consume all light the star previous had (hence the title black hole), and does have "sucking power" it is not a sucking deathmachine. It does have a gravitational pull, just as any star or planet or moon, and to be pulled into this you would have to cross what is called the Schwarzschild Radius. To escape such you would have to be moving at the speed of light. Thus, if anyone has told you that if the sun was replaced with a black hole, or that if the sun turned into a black hole it would consume all the planets or perhaps even earth in its sovereign sucking-power, call them foolish. Earth's orbit would be unaffected by such. The Schwarzschild Radius, if this event did happen, would be approximately 3km. So the Earth would have to be very, very close to this newly-created black hole to be caught by it.
