LOL, I know, I know. It sounds like a ridiculous question to entertain in the slightest. Please hear me out, the more open-minded.
We are told that gravity is what keeps the planets in orbit and it is a principal force or energy in the universe. I've always had a problem with this concept.
1. Why doesn't the moon ever get any closer or further away? Why doesn't anything? Everything seems to keep moving on the same track. This implies, more or less, the same constant speed and trajectory. This is implying perpetual motion. How can something continuously move and not lose speed? Not waver? Gravity is energy but it doesn't apply or retract it's energy to keep a thing going in constant motion. Although to us the planets are moving fast, relative to themselves they are crawling through space. Swinging around one another on an invisible tether. But this movement creates momentum in which the orbiting object is always being pushed outward. If gravity were constant and, say, the moon was in our field, than just like something caught in a black hole, the moon would slowly but surely draw closer and closer to us until it crashed into us. But this doesn't happen. Why?
2. Is Gravity a constant form of energy? They say that gravity is dependent on mass. But if gravity is dependent on mass and the mass stays the same, that means the gravity is exerted continuously merely based on the mass of an object. An energy of attraction is constantly exerted whose intensity is proportional to it's mass. Constant energy. I can never bridge this concept in my head.
3. Black Holes are one of the greatest examples of gravity we have...theoretically. Supposedly it has a force that is able to draw in anything that comes within the event horizon- meaning the point at which even light can escape. There are a number of questions here. If the event horizon exists at a certain point, does that mean that closer to the core the pull is even greater and things exceeding the speed of light can be pulled in?
Two, I have often seen pictures of giant poles of radiation escaping from the poles of the Black Hole. If those pictures are true, how? If nothing can go beyond the speed of light and the Black Hole pulls everything in traveling at the speed of light (especially from its own central area i would think) then it would seem that either these radiation geysers are being expelled at speeds beyond the speed of light or that gravity is not as strong as light or it doesn't exist or exist in the way we think.
Perhaps we can't explain it because, in some way, it does not exist. Or the explanations are wrong? Something is wrong?
Any thoughts to add? It's a topic I can talk forever about.
