There is a definitive truth to global temperatures. They go up and they go down. Hmmm … Imagine that. Global temperatures don't stay the same. What a concept. In fact, it's not even a new concept. Most everything, or should I write Everything with a capital E, changes. While we have yet to find something that does not change, the possibility exists. It's an extremely small possibility, but one nonetheless.

So, going forward with out theory that everything changes, we must conclude that the Earth changes. With that, we must look outward and conclude that other planets change. Our sun changes, the universe changes, and whatever is beyond that, changes.

Well, sure, you think. We all know that. For most people, that is. However, I have yet to see a model in the global temperature arena that includes changes in our solar system. Mostly, you see the "human" factor in the latest warming hysteria. Every now and then, I read about the solar influence on the Earth and on Mars.

But, I have yet to read (and I'm still reading so I could come across it) any article that includes the solar system and universe in its model. Yet, what plays a large part in any planetary body? Certainly a sun would. But what is bigger than the sun? The system which holds them all. And that would play a very important role in a planetary system.

Let's expand or contract that idea. We have a solar system with a sun and nine planets. That system changes just as everything else. What kind of changes would need to occur to effect a planetary system. Hmmm … how about expansion or contraction of planetary bodies?

Let's say that our solar system is in a contracting mode. That means that the planets are ever so slowly, inching their way towards the sun. While not the best of models and certainly one that would be hard pressed to prove, it can happen. Just imagine two larger systems moving toward each other with our smaller system in between. Or imagine a slinky that's elongated and you push each end together. While the spring in the slinky doesn't want to contract, other forces are at work. What this means to us is that over a period of time (dependent on how much force, etc) the Earth's temperature will rise. There will be wobbles and shifts and the temperature won't have a steady incline but cycles with an overall incline upwards.

Let's say the opposite. Our solar system is expanding. There are a myriad reasons and not a whole lot of proof. Imagine a merry go round with several kids on it. When the merry go round starts spinning, the kids feel a force pushing them outwards. The center is the sun, the kids are planets. Now, take a much bigger leap and imagine the planet, Mars, being about where the Earth revolves around the sun. Yeah, it'd go a good ways to explain the Martian environment being what it is now. So, with the theory of expansion, you can see that the Earth just might be headed away from the sun. As with the contraction theory, there are a multitude of variables that would allow for the temperature to fluctuate, but overall, one should see a steady decline.

Or you can view the solar system as being stable and not expanding or contracting. Heck, it'd be the first perpetual motion machine discovered in the universe. Imagine that.
