Newton's third law states when two bodies interact they exert equal but opposite forces on each other. Now we apply this concept to gravitational attraction between, say, the Sun and the Earth. Sun exerts a gravitational force on Earth, and thus Earth also exerts a gravitaional force on the Sun. Now say that somehow, we can block the gravity of the Sun. So now since Sun doesn't exert a gravitational force on Earth, Earth shouldn't exert a force on the Sun as well according to Newton's third law. But we didn't block Earth's gravitational force, and thus, technically, Earth should still pull on the Sun! How can one resolve this apparent paradox?
