Also, as far as I understand it, no one knows for 100% sure what causes gravity, but the blanket model is as good a description as any

It's not that gravity is so weak, it's that subatomic particles have such small masses...

Yes and no. Gravity is extremely weak compared to the other three fundamental forces (Strong Nuclear Force, which holds atomic nuclei together and is transmitted by the Gluon, Weak Nuclear Force, which forces electrons and atomic nuclei to remain apart and is transmitted by the Weak Gauge Boson, and the Eletromagnetic force transmitted by photons). Under general relativity, Gravity is formed when the presence of mass causes space-time to 'bend', as mentioned in an earlier poster. For whatever reason, matter follows this 'bending' downwards to a lower energy state, and so you get gravity. Quantum Physics disagrees, instead postulating what's called a 'Graviton', a very small, very weak particle that transmits the gravitational force between masses. The problem, of course, is that this contradicts the 'space-bending' model postulated by Einstein, and so it represents perhaps one of the biggest physics dilemmas in the 20th century and beyond: How you can construct a Quantum Mechanical Theory that combines gravity with Quantum Mechanics, and explains why gravity is as comparatively weak as it appears to be. This is also the origin for f-in' hardcore theories like M Theory, which operate off the idea that at subatomic scales space suddenly shifts into an 11-Dimensional state. Craziness.

I guess it is weak, in a since, but it holds the planets in orbit, etc... and if you are computing the force of gravity, F = Gm/r^2, the force of gravity is only as strong as the mass that is causing it.

But that like saying electromagnetic forces are only as strong as the charges causing them.

Mass causes gravity, in the classical sense anyway, so why not?

Basic college physics isn't going to give you a good explination of gravity. In fact, if you can unify the theory of gravity with the other forces, you'll become godlike.

But if you compare the two, you can see that a small amount of charge can create huge forces. While you need a massive amount of mass to create a force that is noticeble.

Oh okay I see your point. :thumbsup:

Topic Title: Gravity

I just don't get how it forms.. What causes it to form?!

Did you miss Science class?

God simply waves his hand and the breeze results in gravity.

You better get back in class before you miss any more important lessons.
