I'll to prove that a unique reference frame does exist for the relation motion between 2 objects in the universe such as the earth ans the mars. First, let's talk about a spring. Check the video clip below: From the clip, we can see a law that when we exert a force on an end of a spring, this end will be stretched or contracted earlier than the other end. Supposing that the earth and the mars pass each other with the speed 30miles/s. Then the earth and the mars hook 2 ends of a spring like the image below: So in case the earth is moving and the mars is stationary, according to the law above, the end of the spring attached to the earth will be stretched earlier than the other end. Vice versa, if the mars is moving and the earth is stationary, the end attached to the mars will be stretched earlier. The observers on the earth and on the mars can make this imaginary experiment and determine the earth or the mars is moving. So it must be existent a unique reference frame for the relative motion between the earth and the mars. Anyone tell me this argument is true or false ? Thanks for any comment.

Let’s think about a logical example: When somebody ask you how many people (whom you know) love you, you will easily be confused. But if you were asked how many of them you love, it will be much easier for you to answer. This example implies a physical aspect: we can not count how many objects in the universe which exert the gravitational force on the earth but we can aggregate all the gravitational forces which the earth exerts on every object in the universe. Why's that. That’s because the earth is unique. It is like you are unique. Only you can feel your love with some people meanwhile you hardly can know how many of your friends really love you. This is also true in case of the gravity. The gravitational field of the earth make the gravitational forces on every object in the universe. This gravitational field can be called GravityE2U. That’s why we can unify all of the gravitational forces the earth exerts on every object in the universe. Therefore, in theory, we can make something like this: We will make the new forces. These forces are equal each force of GravityE2U in size and in same direction as each force of GravityE2U. But instead of exerting on every other object, all these new forces exert on the earth only. According to the Newton’s 3rd law: the gravitational forces the earth exerts on the other object is equal and opposite to the forces the other object exerts on the earth. So, that mean the new forces will balance all the gravitational forces which every object in the universe exerts on the earth. And hence, in theory, these new forces can hold the earth in an absolutely inertial state forever (unless the earth collapse with another object such as a planet or a star). This leads to an argument: an absolutely inertial state not only of the earth but also of every object in the universe really does exist. In the absolute inertial state, the status of earth's motion is unique and invariable. So it can be described as a linear equation. We don't have to concern what this linear equation is, just be sure it's linear. So when the linear equation is unique, it means an absolute reference frame to measure the linear motion of the earth is existent. Anybody tell me these arguments are true or false ? Thanks for any opinion.
