Black Holes - this was a deleted topic from the hacker
What I said,
Posting in other topics got me thinking about Space and Black Holes, I don't know too much about them, neither do scientists, but they say that if black holes do exist that there is a good chance that there are more than three dimensions. The three dimensions we see are like up-down, left-right, and front-back. If black holes exist there could be hidden dimensions that we dont know about in space. They are making a and I quote "Man-Made Black Holes" inside a type of chamber.
What they gave for steps for their experiment-
Step 1- Supermagnets in the 17-mile-long LHC accelerate two beams of protons to near light speed and point them on a collision coarse.
Step 2- Small extra dimensions--if they exist--appear when the protons get close together. In effect, they increase the force of gravity.
Step 3- Eventully the force of gravity between the protons becomes so strong that it forces quarks inside the colliding protons to coalesce.
Step 4- This merger collapses space-time and forms a minuscule black hole tens of thousands of times as small as a nucleus of an atom.
Step 5- The black hole nearly instantaneously disintergrates into a dozen or more different kinds of particles as a result of Hawking radiation.
Step 6- A 10-story-tall detector measures those particles as they blast from its center. Those from a black hole would create unique pattern.
Also they are going to do this experiment in late 2007.
Question and Answer I saw in the book I got all this info from.
Why Extra Dimensions?
They could reconcile the major theories of the 20th century: quantum mechanics (the physics of the very small) and general relitivity (the physics of spacetime). Without extra dimensions, quantum mechanics implies that gravity should be much stronger than it is.
If someone were to go through a black hole, they would be stuck at the point of there death forever. People on the outside of the black hole would be able to still see the person inside (frozen) even after the death of the person inside. Because black holes freeze space time. (4th dimension) but there has to be more than just 4 for black holes to still exist.
Space time is frozen inside a black hole, about being able to see someone in there dead, even know they are long gone and not even there. Space time freezes so you see it even though its not there.
Quoting what wikipedia says!
Objects in a gravitational field experience a slowing down of time, called time dilation. This phenomenon has been verified experimentally in the Scout rocket experiment of 1976, and is, for example, taken into account in the Global Positioning System (GPS). Near the event horizon, the time dilation increases rapidly. To the distant observer, a falling object's movement slows down, approaches but never reaches the event horizon. Any escaping photons do not slow down when escaping the gravity well but experience redshifting. From the falling object's frame of reference, it will cross the event horizon and reach the singularity at the center of the black hole within a finite amount of time.
We arent 100% certain that black holes exist in space. They are so far away, we dont see the matter that goes in, eventually the black hole collapses in on itself. Everything disappears, this would be easier to explain with the dimensions thing.
Scientists looking for black holes are looking for a circular movement that is very tight around some type of object. Like a star (sun) on a very small orbit, slowly losing mass, but much faster than a weak dieing star would lose its mass.
