The theory of relativity explains gravity as a curve of space-time caused by the.
If the curve is pretty weak, Newton's laws of gravity can describe.
most of what is seen. Massive or thick objects generate a very strong gravity pull.
The most compact objects are theorized by relativity to have such a strong gravity.
pull that nothing, not even light, can resist the gravitational pull. These objects.
are called a black hole. The main reason is that no light can escape from inside.
a black hole; it has, €œdisappeared from the visible universe.€œ.
Some people don€™t think that black holes really exist; however, most physicists.
believe that they do. Even Einstein strongly denied that black holes exist, thinking,.
as did the majority of his colleagues, that black holes were a only a mathematical.
possibility. He died in 1955, before the term "black hole" was thought.
of and observations and evidence for black holes began to rise. Black holes are .
all very well in theory, but if they really exist, how do they form?.
Here is the basic theory behind the creation, or forming, of a black hole. Throughout.
the life of a star, nuclear fusion in the core will generate electromagnetic radiation.
The radiation that is generated creates an outward push of pressure, which fights.
against the inward pull of gravity. Eventually the nuclear fuel reduces, because.
of the reduction of fuel, the outward radiation pressure lessens. When the pressure.
weakens, the gravitational pull increases and compresses the remaining nuclear fuel.
When compressed the temperature rises, and creates the outward push once again.
.
Ultimately, all fuel is consumed, and the core of the star collapses. If the star.
has enough mass, or is dense enough, then it could become a black hole. Other possibilities.
are that it could either become a white dwarf or neutron star. .
Yeah, Right, Whatever! A young teenage girl dressed all in black turned the corner. She had chains hanging down the side of her black, baggy jeans. What's the first thought that went through your mind? Have you ever seen a nicely dressed young lady surrounded by a group of teenagers who have mult...

Bob Dylan- To me and many other people that have never heard Bob Dylan, he probably seems like a Grateful Dead kind of artist. That's the way I though of him at least. I never really gave him a chance, because I had always heard my mom talk about him and she only listens to Grateful Dead and band...
Censorship In Music Censorship in music is a topic that has brought about much controversy in the past two decades. There have been many different arguments on the topic, however the question remains whether it should be censored or it should not be censored. Before one can form an opinion on thi...
I believe aging has more to it than being the number of years past by since you were born and the wonderings of how many more years to come till you reach downhill along with it. Yeah sure, the dictionaries define it as "the length of past life or existence" or as "showing signs of age", and yeah y...
Ok I know you must think I"m crazy but that will only help prove the point that I"m gonna make to you. Ever since day one I have never quite fit in with any of the people I have met. Well this was all strange to me at first but now that I have looked at the ways you live and compare it to my life I ...
Big Man on Campus "This week's Prep player of the week is Tony Miles," the reporter said as the crowd at the pep rally went crazy. The reporter continued, "In the first game of the 1996 season, Tony had nineteen tackles, three sacks, and a fumble recovery from his middle linebacker position. On ...
Yeah, I explained I"m just surfing the net and watching Hey Arnold on Nickelodeon. ... Yeah that would be totally awesome, I really need to get out of this house. ... Yeah that is true she said, then without a blink of the eye she typed out," Dude how about Mexico"? ... Yeah, I exclaimed that would be really fun and since we were all eighteen their wouldn't be a problem purchasing the bottles. ...
If I were to say, "Um, ah, like, yeah I"m here to tell you that cars are cool", you wouldn't take me seriously would you?" ... If someone got up on stage and said, "Um, I think cars are kinda cool and uh yeah I really like cars" no one would be convinced that cars are cool because the speaker didn't give any proof or examples to back up his or her statement. ...
One day a man sitting in a tree came up with an idea that he would define art. This not all too surprisingly is not the way we have evolved. Instead we have no definition for art other than "the conscious use of skill and creative imagination ." At the time that I went to see the comical play Art I ...
