Conversation 3
: Let's talk about the concepts of "concurrence and causality": We naturally assume that there must be a causal relationship or dependency between two things if they occur together consistently. This is how people think and reason. Deflection is accompanied by relative motion and vice versa, and this simultaneity can be seen as mutual dependence.
Since we have no control over deflection, but we have control over motion, the common belief is that motion is the cause of deflection. This requires discussion.
: Relative motion and deflection go hand in hand, and this relationship can be thought of as reciprocal causation.
: I don't think that the motion of objects and the deflection of space are mutually causal. In fact, I have a whimsical idea that space deflection is the cause, relative motion is the effect, and perhaps force or interaction is the result, to be precise.
: Let me think about it. This can seriously challenge our common sense and intuition. Well, let's see. However, in our conversation we refer to the concomitance of space deflection as "concurrent", which means that there is no time lag or gap in its occurrence, no matter how far apart the relative references of the frames are. The concurrence of mutual deflections between frames has no before-after in time sequence and no limit to the speed of light.
: The "concurrent" of space deflection is the only nature beyond the limit of the speed of light in the physical world, so the definition of the word "concurrent" in our discussion is also unique.
: One thing to think about: The light we observe as an aberration was probably emitted thousands of years ago, or even earlier, and the aberration of the space deflection was concurrent with the earth's movement around the sun at one revolution per year. Could it be that the path of the light from the stars was changed about midway through, given that the deflection is known to be simultaneous? How did the light on its way to us know how and where the earth was moving?
: That's a good question. One thing I can say is that the occurrence of the space deflection has nothing to do with the presence or absence of light. The light of the aberration is the proof of the existence of the space deflection.
: Let me see. Let me give you an example. You are standing to my left, Jinkai and I are standing diagonally in line with the toy train tracks across the table. Jinkai places the electric toy train on the track facing me. I lift the corner of the table and move it to the left, while the toy train moves halfway so that the diagonal is facing you. This makes the train approach you. The train does not know that the table is going to bend or that it has turned at an angle on its way to you. I compared the space frame to the table and the track, and the light beam to the toy train. Does this answer your question, Jinkai?
: Chuanjiang, your example is OK, but inaccurate. Stellar luminescence is an isotropic light source that emits countless beams of light in all directions, so no matter how complicated the deflections are, there is always a beam of light from the star that hits you. The deflection of the frame means that all the light emitted by the light source is also framed and deflected. This concept is difficult to understand, but it can explain many phenomena without contradiction.
: In fact, the train is still moving towards you while I am so quickly turning the corner of the table. It shows that the deflection happens "concurrently" while the light is still traveling far to the earth. We have talked so much to show that this is strong evidence that the deflection goes beyond the speed of light, and that is why it is called "concurrent", which is the most significant finding. We can apply the concept of deflection generally, as this is the most important feature of deflections.
: Deflection apparently precedes light.
: Wait, I have another question: How and where does the toy train go if you move the corner of the table to the left and the other person moves the corner of the table to the right?
