Homework #2

BLACK HOLES

 

It was a star vastly larger than our own sun. For hundreds of years this giant star burned brightly in its corner of the universe. Then at the end of its lifespan, a bizarre thing happened. The dying star began to collapse in on itself. While the star was in in its death throes (violent spasm), all the matter that made the star was squeezed together into a smaller and smaller area. Soon the star measured no more than a mile across. Its matter so tightly packed that a chunk of the size of a small marble weighed as much as a mountain.

As the dead star continued to fall into itself, it brought with it every bit of matter in the area. Every speck of dust, every stray atom, was dragged into it. The star had become a black hole. A black hole is a small area of matter so dense that not even light beam can escape the pull of its gravity. 

Since no light can leave black holes there is no way for us to see them. They are invisible. We know of their existence because of the strange things that happens around them. Light that is traveling through space just vanishes.  Just how wild is a black hole? Let's take a look at gravity.

 A common expression related to gravity is,  " what goes up must come down."  When someone trows a ball into the air, it must return to Earth. This happens because Earth attracts the ball, or pull it toward itself. It is only the great thrust of giant rockets that allows the Space shuttle to escape the pull of Earth's gravity. On a planet with double or triple Earth' s gravity objects would act quite differently, because the pull, or attraction would be much stronger. A ball thrown in to the air would not be very high and it would plunge quickly back into the surface.

 Beams of light, however, would have no trouble at all escaping from this planet.  Even if the force of gravity were increased a million times that of Earth, light beams would not be affected. Human on such world, thought, would be crushed flatter than their own shadows. Only if the amount gravity were many billions of times stronger than Earth would bend light beams back to the surface. Black holes are the most bizarre objects in the universe. Nothing leaves a black hole. 

1. A black hole results from the death of a :
a. Sun like our own.
b. Blazing comet
c. Giant star.

2. Gravity in a black hole
a. Twice that of Earth
b. a hundred times that of Earth.
c. so great that even light can't escape

3. Black hole matter the size of a marble
a. weighs as much as a mountain.
b. takes two people to lift
c. would sink several feet into the ground

Writing exercise
Write a short story minimum 50 words  using in some bizarre way a black hole, it could be ridiculous,  tragic of comical.
