A Trip to Oblivion
         
                So, you've come to the end of the line and you want to end your life in a dramatic climax that will have people talking for years.  You decide to jump into a Black Hole to clear your need to know everything about these mysterious points in space.  Setting your spaceship to full throttle you head straight for the black hole.
                You don't feel anything out of the ordinary at first.  Just like landing on a planet, gravity begins to get stronger.  As you reach the horizon though, you realize the pull begins to become really strong.  Your body, being composed of uncountable numbers of points begins to stretch towards the black hole starting with the point closest to the singularity.  The pull of gravity increases so rapidly that your body would tear apart before you even reached the singularity.  But let's assume for educational reasons that you don't get torn apart.  You see yourself stretching towards the singularity being led by that point that was closest to the singularity.  You try to escape by turning your boosters on to full throttle but it is impossible.  Not just because nothing can travel faster than light, but because space and time inside the horizon is so messed up that the distance you traveled becomes the past and the distance you are about to travel becomes the future and, as mentioned earlier, trying to escape is like trying to avoid the next minute in your life.  You find yourself pulled towards the singularity and crushed by its immense gravity.

                Now, if someone were to observe you from quite a distance from the black hole, they'd never see you enter the horizon.  Let me explain why.  Everything seems normal to them while you approach the black hole but as you get closer to the horizon, time seems to slow down and your actions get slower and slower.  There are two theories to this, one involves the concept of space time being distorted, the other, which I believe makes more sense, involves the trapping of light.  I will go by the one which I think makes more sense.  What is happening is that the light begins to be pulled by the gravity of the black hole and takes longer to get to the eyes of the viewer.  But wait...didn't I mention before that light doesn't slow down when affected by gravity but rather increases wavelength?  That would mean that the images projected towards the viewer wouldn't come out slower but rather at different colors.  On reading about this, I too was confused and still am about how light reacts to gravity.  So in true honesty, I don't know.  But one thing is for sure, once you cross the horizon, light can no longer escape to the viewer and as a result you would just seem to disappear or the light escaping just before that point would take so long to reach the viewer that it would seem as though you never fell inside the horizon.
             
             

        What About Wormholes?
                Now your probably wondering, 'What about that stuff I saw on Voyager last night?  Don't wormholes that lead to other dimensions exist?'  The answer to this question is yes and no.  In the scientific world, all equations can be substituted for the opposite to produce something that is totally different.  And that is how we would get wormholes.  But in true physical science, this is impossible.  First of all, a wormhole is mainly a black hole connected to a white hole.  A white hole is the opposite of a black hole and as a result spills things out instead of sucking them in.  For white holes to exist, there would have to be an object that would have so much inverted gravity that it kicks even the heaviest object out of its orbit which is almost absurd to think of how any of these could be formed.  And since white holes don't exist neither can worm holes.  Meaning, if you were to jump into a black hole you'd quite simply just die, not wind up in another dimension or time or whatever sci-fi fanatics like to believe.
