How does gravity affect matter, yet remain unaffected by the interaction?

Question

Energy, such as light, propagates from the sun, but when it strikes an object such as the Earth, it stops or is reflected. Other small particles propagate through the universe and pass through the Earth unaffected by it, but they also do not affect the Earth.
Gravity, on the other hand, strikes the Earth, it acts on the Earth by pulling the Earth toward the sun, but Gravity continues on out into space without seeming to be slowed down by its interaction with the Earth. How is this possible? It seems there is no way to block gravity. Is it reasonable then to infer that gravity does not therefore propagate? Did Einstein believe it propagated?

Answer 1

Glad to see you're thinking, but this is an easily answered question.

Take for example a magnet. Regardless of what is in front of your magnet it will still attract an object to a distance equal to its strength.

ex:

.....(|)<<<< <[]<<<<<<<[]

......^..............^...... ......^
Magnet......Metal..... ..Metal
.................Object.... Object

The magnet is going to exert force on both of the objects without interference from first object.

Based on your definition of propagate...come to your own conclusion...that is the joy of thinking...we all have our own thoughts.

Answer 2

the Gravity force is now considered as a strange force, because no one can explain its charateristic, we can only know that it is the interaction between two objects which have weight in the university

around the Earth there is a magnetic field which protects the Earth from the ultra violent ray from the Sun, this is the reason why the some percents of light from the Sun reflects when it comes to the Earth

Answer 3

change are to be cancelled out or to be normlised. remember that befopre the big bang all the matter was concentrated inthis "egg". therfore infiite mass was closed in such a small space. after the explosion all the mater traveld (and travles) witht her memory of this attraction and all the matter tend to attract other matter in order to complete the original picture.
now gravity is created through a field. the outcome of gravity is present and can vbe derived by having a body that creates the field and another body in it tha expiriences the force of attraction from the field to the body. no bofy exerts force. it creates a field and the field is responsible for the force. (field theory). gravity is the outcome of the field attraction due to the exsistance of a body.
