What are Black Holes?

A black hole is theorized to be a collection of collapsed matter of whose gravitational pull is so strong that not even light can escape its force. The matter is is forced in a very, very tiny area and therefore the matter is very dense. Since light cannot escape, they are considered to be truly black. This, obviously, makes it hard to detect an actual black hole, and therefore, have only been theorizd to exist. These theories are slowly turning into "conclusive evidence." This evidence includes the particle dust given off from matter entering the black hole, as well as observations of orbits of bodies near the black hole.

Black holes are usually formed after supernova explosions, in which the remnants of this explosion …show more content…

Anything that enters this radius will not exit, due to the tremendous amount of gravitational pull.

So, How do we know?

Again, as mentioned earlier, we can't directly observe a black hole. We can, however, make observations to the surroundings around the black hole. It used to be that theorists were the only scientific persons who acknowledged an existence of black holes, however, today, the story is quite different. The popular idea today is that black holes do exist and are common in all the galaxies so far investigated. One reason is Einstein's theory of General Relativity. This theory accounts for the existence of black holes, and if they do not exist, then the General Relativity theories by Einstein would be wrong. Considering all the tests and experiements done to date to try and disprove this theory have all been rejected, this seems unlikely. Also, scientists today look for high concentration of mass in a small area. Calculations and technology allow this to happen. Another factor in proving the existence of black holes is the Hubble Space Telescope. The Hubble Space Telescope has accumulated a large amount of data and information supporting the existence of black …show more content…

Now they're going for their daily intergalactic space ride in their seperate Super-Speed Rocket Cruisers when Dick suddenly loses control of his Cruiser and ends up crossing into the Swarzschild radius of a black hole. Jane, with good intuition, knows there is nothing she can do. So, what does she see?

Jane will never actually see Dick reach the "event horizon," or the boundary at which light can enter but never escape. Dick will surely reach the event horizon, but not from Jane's perspective. As Dick becomes closer and closer to the horizon, the light emitted from Dick will take longer and longer to reach Jane. As Dick reaches the horizon, the light will not be able to escape, and therefore never reach Jane. Dick will appear to be "frozen," or standing still to Jane.

Alternative:

Dick loses control of his Rocket Cruiser, but this time ends right on the brink of the horizon. He hasn't crossed the horizon, but is as close as you can get. He returns to Jane to find her much older, and yet hardly any time has passed to Dick. What's going on
