What Balck Holes Are Essay

1098 words - 5 pages

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 existance 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 facinating is the black hole theory. Not any star can become a Black Hole. For instance, the possibility ...view middle of the document...

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. This explains why all the black holes do not swallow everything up in the universe.Inside the event horizon is where the major speculation begins, just what happens once you cross the event horizon. Well, once you cross the event horizon, you'll be spinning around the center at the speed of light. As you get closer to the center, or what scientists call the "singularity", the theory of the speghetti effect comes into play. That is, the gravitational pull of the center of the black hole is greater at your feet than your head, thus pulling stronger at your feet, and stretching you out to a point of infinite thinness. This same force is what causes the tides in our ocean, hence the name "tidal forces". The time in which it takes you to witness this effect depends on the size of the black hole. A smaller black hole means that its singularity is not far away, thus killing you quicker. If you could somehow get into a horizon safely and look around, images around you would be distorted. And since light can go into a black hole, you can see outside images fine. But light won't be able to bounce of you and back, so no one would be able to see you.Although living long enough to reach the singularity is just about impossible, if you could reach it; no one knows what would happen. Basically, you would be in a place where time does not exist and all of Einstein's laws will fail.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 quantity of mass in a small area, there is a good chance it...
