By gravity I meant the fact that EVERY single object in existance has it's own gravitational field.
They do. If an object has mass (or, more precisely, inertia), it has a gravitational field. This is a fundamental part of Newton's second law, and is required by general relativity. Have you had an entry-level physics class in school? They should have discussed gravity in that class, and if they have not, ask your physics teacher about how gravitation works. It's fairly simple and quite logical. Here's the wiki article about universal gravitation; it's a good read:

And I know the part of what you said about certain elements emitting specific colour is true but take into consideration the size of the Sun, which is presumably small compared to other stars. How would we know that there isn't vast amounts of Mercury or Cobalt or Zinc in the center of it? The size of the star would prevent any evidence of these at all.
Why would its size prevent us from measuring its composition? I admit, I'm not an expert in astrophysics (far from it), but we can measure quite a few elements and their relative abundances, including iron, chromium, calcium, oxygen, magnesium, sulphur, neon, and others. Here's an interesting explanation of stellar compositions, and it links to pages with more in-depth discussions of stellar composition:

And I stated before that no theory can be proven, and got bashed for it.
We're just making sure you understand why this is, and why it is not the problem that it is often perceived by laymen to be. I'm sorry if we came off as rude.
I don't really care if anyone here is attacking me, I mean I get that enough at home from my parents, even my grandparents. The internet is just my escape.
That's too bad. I hope you are patient with them. I know it can be hard.
The fact that there is so much that I don't believe in or comprehend is a great part of why I want to put bullets inside my skull.
But you know that there is a lot you don't comprehend, and this will sound pretty cliche, but knowing is half the battle. When you know that you don't know, you're able to open yourself up to education. Learning about the world around you is, in my opinion, one of the most rewarding personal ventures in life. Heck, it's why I'm 25 and still in school. The more I learn, the more beauty I see in the world around me, and the more beauty I can see, the more I want to know about how our world came to be as it is. I hope you feel the same way, and I hope the only thing you put in your skull is knowledge.
Orogeny, you are one of the people that I look at and smile because they actually have some sense of sanity and intelligence, unlike 85% of the people I encounter every day.
I am humbled by your compliment. I teach the lab portion of introductory geology classes at my university, and nothing makes me happier than hearing my students talk about how much they're learning. I hope you continue to want to learn, and feel free to ask me (and the other members of this board) whenever you've got a question. We're more than happy to help.
