Till now, the gravitational field is studied and understood under the assumption that a gravitational field was not interacting with other gravitational fields.
Under this assumption, it is assumed that a gravitational field is a static sphere or equipotential surface. It is analogous to an electric field. In Einstein’s general relativity, it is described with curved space.
But, in fact, none of the gravitational field is isolated from other ones. All of the gravitational fields are always interacting with others. So, the gravitational field only can be right explained and understood with the interacting fields.
The conclusion is: till now, no theory of gravitational field is valid in describing the actual gravitational fields. We need new theory for the gravitational field.
