Black Holes

Tuesday, August 14, 2007 posted by Stars & Astronomy

I have no interest in becoming an astrophysicist but I find the concept of understanding space interesting. Black holes, in particular, are a great fascination. What are they? And what happens to all the stuff that is sucked into them?

To understand a black hole you have to understand that all matter is residing in an energy field. If that energy field were spread out wide and flat you would find that all matter (we know of) is on one side of the field and on the other side (scientists believe) is some sort of anti-matter. This field is commonly represented as something like a wide trampoline. As heavy-matter objects press down on the trampoline nearby objects slide towards them. If you’ve seen any programs on Einstein’s theory of relativity you will know what I am talking about. What they forget to mention is that the trampoline is a field of impossibly pure energy. To be exact, it isn’t energy, but a limit of energy.

Understanding this field is important. All stuff consists of a ratio of mass and energy. Now it is well known that mass and energy are the same thing, just in a different form. Your body is a mass but it also has a lot of energy. There is no such thing as mass with no energy. You are on the Earth and it is spinning very fast so you are moving. It is my theory that it is essentially impossible to achieve 100% energy. Stuff that is mostly energy resides very close to the aforementioned field. Stuff that is mostly mass resides far away from the field. You can get your mass closer to the field by moving but it isn’t enough of a change to notice anything.

Black holes are very massive and contain more energy than any star. Black holes make an incredible indention in the field and they are very close to it. To use a visual metaphor, just take any old garbage bag, pull it tight and press on one tiny spot with your finger - harder and harder. It stretches and stretches and then it breaks. Can the field supporting all of the energy and matter in space break? Why not? What would happen if it did? I began answering those questions by realizing that space is expanding. Why? What if the field isn’t just a flat field but a bubble? What if all of matter and energy is inside the bubble pressing out on it? What if something pokes a hole in that bubble? Wouldn’t it just make a new bubble? You get one bubble with bubbles growing off it. Then, bubbles can grow off those bubbles.

Now, it is easy to see what happens to the stuff that is sucked into a black hole. It just slips out of one bubble and into another. Exactly what happens isn’t too nice to think about. To make the jump, it must pass through, nearly touching, the field. Anything close to the field is nearly pure energy without any mass. Is it possible to convert mass to energy and then back to the same mass structure? Not that I know of. So, if you tried to jump through a black hole, all of your matter would be converted to energy and that energy would spew into the new bubble. Eventually, that energy will become high energy particles, which join into subatomic particles, which make atoms, which become parts of new things - just not you.

This all brings me back to the beginning of space - the Big Bang. Was it a bang or a pop? Is space just a bubble created by a black hole in another bubble? The only argument against it is the theory that the amount of matter in all of space is constant. Of course, nobody has ever actually went out and added up how much matter there is. There could be a little hole off in space somewhere that leaks energy in while black holes leak it back out. Eventually, the incoming hole will run out of energy to leak in. Then, all of our energy and matter will eventually leak out and all that will be left is a deflated bubble.
