Most of this will just be amplification to Moose's post. I agree with everything he says, but want to add a bit.

Like Moose said, there arent alot of experts here, but do remember that there are experts here. People who know more physics than 99% of the population of the planet. Some of us are active in the scientific community. This leads to the very clear distinction between asking a question and making a claim.

If you ask a question, most of us will be more than happy to answer it to the best of our ability. If you show a willingness to learn, you will probably be flooded with answers to your questions, for as long as you care to keep it up.

However, if you make a claim, you are implicitly stating that you think you know enough to change the laws of physics. In that case there is one response from most of the experts. Prove it. In scientific circles, this is only done one way, by attacking the claim tooth and nail. We tear it to shreds and see if anything stays intact. You are no different in that respect.

Remember that some of us have more than a little knowledge of physics. Alot of things in physics which seem like they arent thought about are simply theories that were disproved decades ago, and alot of the experts here already know this. Other things in physics are extremely complex, and there are no simple answers. Gravity falls into this category. Alot of the experts here arent very sympathetic to someone who wants to change the laws of physics but dont even understand basic physics. Alot of times, when someone has problems with the basics, that means that the explanation of why someones idea is wrong wont even be understood by the person who presented the idea in the first place.

Also, Stephen Hawking's books are nice, but when he writes them for 'laymen', they ususally end up pretty science free. They are good for the very basic concepts, but bad on the details. The details are important.

Lastly, America is a free country. You are free to speak you ideas and I am free to tell you that you dont have a clue about what you are speaking about. Freedom works both ways
