Transcript of Black Holes

By: Quinzette, Danelle, and Siddonie Black Holes What are Black Holes? How do Black Holes form? Karl Schwarzschild was the first person to discover black holes. In 1916, he used Einstein's theory of relativity, he began to make calculations about the gravity fields of stars. Who was the first person to discover Black Holes? Do Black Holes affect the galaxy? Black Holes do not wander around the universe, randomly swallowing worlds. They follow the laws of gravity just like other objects in space. The orbit of a Black Hole would have to be very close to the solar system to affect earth, which isn't likely. Are Black Holes doorways to other parts of the universe? Could Black Holes destroy planet Earth? http://blackholes.stardate.org/resources/faqs/faq.php?p=black-hole-formation References Black. Holes is a place in space where gravity pulls in so much that even the light cannot escape.The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. A black hole forms when any object reaches a certain critical density, and its gravity causes it to collapse to an almost tremendously small pinpoint. Stellar-mass black holes form when a massive star can no longer produce energy in its core. With the radiation from its nuclear reactions to keep the star to conserve energy, gravity causes the core to collapse. Thank You For Watching! Anything that falls into a black hole is trapped there, and it can't come out elsewhere in the universe. No wormholes have been detected and the theories say that as soon as anything tries to enter the wormhole, it would collapse.
Black holes suck up anything, they are a major problem to every galaxy because eventually they can get big enough to devour the entire galaxy, but in our galaxy case will no be affected by black holes. doubleclick.net www.nasa.gov www.wiki.answers.com
