i figured people in the thread would know that already, since the topic was already adressed

"Yes"

its the fact that earth has a mass that is much larger than our own [and the sun has a mass bigger than the earth]

technically, we are all gravitated to one another [to a unimaginably small degree, but gravitated none-the-less].

all mass has a tendency to gravitate toward one another [exept exotic matter which acts in the opposite way] and the earth is an example of this.

gravity is equal to G [universal gravitational constant] multiplied by the mass of one object and the mass of the other object that you with to compare. all divided by the square of the distance between the two objects.

the "iron core" has nothing to do with it, it may just make it less massive. thus having a lessened effect on us all.

also, i dont know if you purposely did it, but i like how you wrote "and black holes will exert a force on any matter.." instead of "black holes will have matter gravitate inward" or "black holes will suck matter in"

because it is speculated that black holes (and the exotic matter there-in) work omnidirectionally, sucking one way then pushing after reaching the center. and vice versa. if worm holes only sucked in, as many people believe, then anything traveling through them would be stuck in the middle, unable to exit the mouth on the opposite end.

You had Einstein with his theory of relativity (e=mc^2), and you have the string theorists and their respective theory.

All in all gravity is a THEORY, we know its there, we just really don't know what it is (I hope that makes some sense).

Thats basically all I have to say, I'm sure I meant to put more in there, but lack of sleep and a large headache prevent me from doing so...

anyway.

gravity is more than "if you jump off a building you will fall"
yes, it is a theory. but it is how we describe the planets revolving around the sun the way they do. and many other things that happen not only on the planet, but in the universe as well.

GRAVITY as we describe it exists. whether or not we are wrong about what it actually is is the theoretical part.
