Let there be a solar system without Earth. Now what happen if we place the Earth suddenly on its actual position does the gravitational force of sun acts on it immediately because of its pre established field or the force will act after 8 minutes (the force reaches with the speed of light) I just want to know that does field have an emergent nature like light.
Edit: can some body please tell me how can i collapse my question.I just want to know that does pre existing field cause a force instantly or not? But it's put on hold because it's off topic. (Sorry for bad english)
