The gravitational forces on Jupiter. The gravity is much stronger on that planet.

The gas is quite dense, and in fact there is a small rocky core, covered by a layer of metallic hydrogen. The ultimate answer is that a massive object does not require a core to remain cohesive due to gravity. It just needs sufficient mass, and the mass can be in any phase.

Whoever thought this concept up is totally wrong. Do you remember when the planet was struck by large, fast moving asteroids, and the impact made a cloud of debris greater than the size of earth? If Jupiter were actually a gas, the fast moving, dense mass would have passed through the planet. Jupiter has a very vast gravitational field. This value is found by the concept of c2 = E/m. It takes energy to perform work. This could not be accomplished in a mass of gas. http://360.yahoo.com/noddarc

Firstly, it is unsure as to whether Jupiter has a solid core or not. However, a planetary body (or star) does not need a solid core to remain intact. "Solid" is just a STATE of matter, but whatever state it lies in, matter still exerts gravitational forces on other matter. So regardless of it's state, Jupiter is still a massive body, and it's gravitational force keeps it together, as if it were experiencing a force pulling it towards its centre.

Of course Jupiter has a core.

Jupiter's gas just gets denser as it gets closer to the "core"

I dont think its just gas remember the collision with the asteroid? I am sure it must have a core.

The same way the guy driving down the high-way with a mattress on his roof holds it down with ONE hand!
Actually, it has gravity and atmosphere.

It has a core, a really dense core.
