I was at Borders and saw a book called Logical Universe and the author is offering a reward to anyone who can provide evidence that gravity is from objects pulling on one another.

In his excerpt from the web page http://www.inertialpress.com/html/challenge.html
he says,
"I Michael F. Jones, author of Logical Universe will pay $15,000 to the first person on Earth to provide solid, verifiable evidence that gravity is due to objects pulling upon one another."
First of all, gravity isn't DUE to objects pulling upon one another. Gravity is a phenomena that attempts to explain how and/or why objects are attracted to each other. To say that it is "due" to this attraction isn't correct. It's like saying that when objects approach each other, gravity forms. Which isn't the case. So, that's kind of the trick. Essentially, that can't be proven because it is wrong.
Secondly, it isn't correct to think about objects "pulling" on each other, because objects aren't really pulling on one another. That's just a way to think about gravity. Einstien showed us that gravity is a dilation of time and space due to the presence of matter, and not a tug-of-war. Rather it is more correct to think of gravity as a form of relative motion in which time frames are different for objects of different masses.
I hope I haven't crushed your dreams of being $15,000 richer.

Proof?
Look at the Milky Way.
It's in a binary system with another galaxy for which I forget it's name.We have more mass than the other galaxy.We ae slowly pulling one sun at a time from that galaxy.As we gain more and more the scale will tip faster and faster.In the next couple billion years it may completely be inside us.And honestly, I just learned that today.Hope you win $15,000 because of me.

Gravity hasn't been objects pulling on each other since Albert Einstein couldn't sleep one night. Objects mass distorts space, causing other objects to sort of roll down hill toward them.

Newton's law of universal gravitation states: "Each particle of matter attracts every other particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. "
Or:
Gravitational force = (G * m1 * m2) / (d2)
Where G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses.
G=6.67 x 10E-8 dyne * cm2/gm2. A dyne equals 0.001 gram weight.
And then there is Einstein's definition of gravity:
"The general theory of relativity addresses the problem of gravity and that of nonuniform, or accelerated, motion. In one of his famous thought-experiments, Einstein showed that it is not possible to distinguish between an inertial frame of reference in a gravitational field and an accelerated frame of reference. That is, an observer in a closed space capsule who found himself pressing down on his seat could not tell whether he and the capsule were at rest in a gravitational field, or whether he and the capsule were undergoing acceleration. From this principle of equivalence, Einstein moved to a geometric interpretation of gravitation. The presence of mass or concentrated energy causes a local curvature in the space-time continuum. This curvature is such that the inertial paths of bodies are no longer straight lines but some form of curved (orbital) path, and this acceleration is what is called gravitation. "

Gravity is not from objects pulling on each other.

I don't believe anyone has fully explained gravity yet...
I don't understand why gravity is called a weak force when
the gravity in a black hole crushes all other forces into oblivian...

the earth has a shitload of mass and since its moving so fast everybody sticks to it because of centriphical force. It's pretty bad ***...
