Gravity bending due to another Gravitational Source

Click For Summary
SUMMARY

The discussion centers on the concept of gravity bending around other gravitational sources, drawing parallels to light bending as described by Einstein's General Relativity. It asserts that while light is deflected by gravitational fields, gravity itself does not bend in the same manner. The conversation also explores whether a satellite in Low Earth Orbit experiences gravitational pull from the Sun before it is directly aligned with it, concluding that gravitational forces from both the Earth and Sun act simultaneously, regardless of the satellite's position relative to the Earth's umbra. The distinction between static gravitational fields and gravitational radiation is emphasized, noting that the latter requires general relativity for accurate description.

Does the effect of Gravity get bent like light around another gravitational source? If the object is close enough to the Earth does the Earth's gravitational force bent the Moon's or even the Sun's gravitational effect on that object before that "line of sight" event occurs. As Einstein's General Relativity was proven in 1919 with an solar eclipse of the Sun, light bents with a gravitational source why can't gravity.

Will a Satellite around Earth in Low Earth Orbit feel the Gravitational pull before passing from the protection of the Earth's Umbria or will it feel nothing until the Sun is directly in front of it? If so is there any mathematical evaluation of this occurrence?

It doesn't make sense to describe a static gravitational field as being deflected by other objects (since deflection implies motion). A gravitational field that is changing in the right ways will produce gravitational radiation which (as long as they are sufficiently small in energy density and the deflecting object's gravity is not too strong at the point of closest approach) is deflected the same way as light.

The static gravitational field of an object (such as that from the Sun that causes the Earth to orbit it) is not blocked by anything. When a satellite passes behind the Earth wrt the Sun the gravitational force on it is still the http://en.wikipedia.org/wiki/Vector_sum#Addition_and_subtraction" of the forces from the Earth and Sun. Note: considering gravity to be a vector force is only valid in the Newtonian approximation, gravitational waves require general relativity and do not exist in Newtonian gravity.
