EVEN THIN GALAXIES CAN GROW FAT BLACK HOLES-------------------------------------------Like people, galaxies come in different shapes and sizes. There are thinspirals both with and without central bulges of stars, and more rotundellipticals that are themselves like giant bulges. NASA's Spitzer SpaceTelescope has detected plump black holes where least expected -- skinnygalaxies.http://spaceflightnow.com/news/n0801/14thingalaxies/
Can you tell me more about black holes? They have always fascinated me, but I don't know very much about them. . .
"Black holes are some of the most mysterious objects in the universe. Imagine yourself standing over a bottomless, pitch black pit. Everything around you was being sucked down into the pit, even the light! Everything that is being pulled into the black hole seems to be moving slower, but is actually gaining speed rapidly until it reaches the edge of the pit, which is called the horizon. This is point of no return- anything that reaches this point will never come out. Then, the object is pulled into the pit, and is also shrinking in size, until it finally collapses into what is called a singularity (a dimensionless object with infinite density)." -from http://library.thinkquest.org/25763/mindex.htm
actually that's wrong at least the nothing can escapes it part, I thing it's called nero's but those go through everything including the earth!
THAT IS SO WRONG!!!!
1. it would be EASY to find "wondering" black holes if thing um? DISAPPEAR!!!
2. that has probably already happened remember? thousands of years for light to get here?
3. there is another form of colasped star that's called a neutron star that creates the light house effect to
4. If the light "bends" as it says it would it would simply disappear
5. NO STARS ARE EVEN CLOSE TO EARTH
must I go on I read the first two paragraphs and that was enough
Light is composed of elementary particles called photons. The photons differ from the other elementary particles beacuse they have zero rest mass.
However, according to the Theory of General Relativity, photons are themselves affected by gravity; their normally straight trajectories may be bent by warped spacetime, as in gravitational lensing. To be more precise, the gravitational field of massive object (such as a galaxy cluster or a black hole) can warp space-time, bending everything in it, including the paths followed by light rays from other sources.
still that thing is wrong
...still got a lot wrong.....
A black hole is formed when a dying star above the Chandrakhesar Limit (about 1.5 times the mass of the sun) runs out of fuel and cools down, the stars gravity starts to pull itself inward. As the star contracts the particles begin to move faster, to avoid hitting each other. Things must be moving faster and faster to reach escape velocity. The event horizon is the distance at which nothing not even light can escape the black hole. The event horizon is formed by the rays of light that just fail to escape the gravitational field. Instead they circle the black hole forever.
