Gravity

Gravity is caused by rotation of large objects.  Mass alone does cause gravity, but an object of large mass and surface area will cause gravity based on the speed of its rotation generating force.  This gravity will affect other bodies in space, causing moons and asteroids to rotate and orbit, which create their own less powerful gravity due to the smaller size of these objects.  Multiple small objects could form a loose surface area with some gravity generated from their speed and rotation.  

The Earth's gravity is not caused by a "spinning molten core," but by the rotation of the entire mass of earth causing gravitational force based on the size of its surface area.

Absense of rotation equals zero gravity.  If the Earth stopped rotating, we would all start floating towards space.

Newton stated objects are attracted to each other, and objects of greater mass attract each other more than objects of less mass.  Why should we still believe this?  Science should have a better theory after all these years, especially with the limited knowledge Newton had in his day. 

Objects don't attract other objects because they have more or less mass.  People do not get sucked in to buildings or mountains, nor do smaller creatures or objects.  Gravity is not caused by just mass itself.  Gravity is a rotational force, caused by rotation times mass.  Something has to generate gravitational force, it can't just cause gravity due to greater mass with no movement.  Fission also generates gravitational force. 

The so called "laws" of gravity need to go back to being theories, because someday they will be replaced by a better theory.  Accepting them as true due to the infallible word of Newton is flawed and dangerous.  Science has learned far more about physics since the days of Newton.
