all three move at the same constant speed that is c. the reason to prove it is that gravity waves travel at the same speed. And even the effects of gravity travel at speed c. That is the reason why I say that spacetime's structure can only change at this speed. Am I right to say that the speed of light is finite because spacetime's structure itself needs to somehow accommodate EM waves passing through it? Am I correct that nobody has yet combined gravity with QM? In QM currently they say every particle has its own wavefunction that describes its probability distribution at and around its coordinates in space. GR explains the effects of gravity, but it does not explain how they work. Since the EM waves can only propagate through space with speed c, and the effects of gravity can only propagate with the same speed, and even gravitational waves can only propagate with the same speed, it would be accurate to say that information can only propagate through space with speed c.
Now the reason for that is that space itself can only change its own structure at this speed. Why? Lets combine GR with QM. Lets say not only particles have their own wave function, but space itself also "stores" a wavefunction for each of its spatial "coordinates" or position. So in space each 3D coordinate would not only be a spot, but it would also have a wavefunction itself. Just like how QM also says space is not empty, it has Q Fields everywhere in it. So if it has Qfields everywhere in it, it can have a wavefunction everywhere.
This wave function will do the same for a certain spatial coordinate, as the normal wavefunction(that belongs to the particle itself) does with the particle, it just shows the probability distribution of the particle at its own coordinates, and around it in space. So space itself would not only have Qfields at every single spatial coordinate, but also a wavefunction. Lets say there is a wavefunction for point A and point B. If point A and B have no particles at their positions (so they are "empty") then the wavefunction for point A will show a neutral distrubution of possibilities (0 most likely for its own coordinates and the surrounding spacecoordinates) .
The wavefunction for point B will show the same. Now if a photon enters point A, the wavefunction of point A will start changing and will first show higher probabilities at its surrounding spatial coordinates in the direction the photon is coming from, and then as the photon passes through point A, the wavefuction of point A will show higher probabilities along the way the photon passes through it and its spatial surroundings, eventually at the center coordinates of A and then in the direction of the photon's passage.
Eventually as the photon passed through point A, the wavefunction for point A will show lower probabilities at the spacial surrounding coordinates from where the photon came, and at point A's center coordinates, and will show higher probabilities in the direction the photon passed on. Then, as the photon moves towards point B, the wavefunction for point B and its spatial sorroundings will start showing higher probabilities in the direction the photon is coming from (that is the direction from point A), and as the photon passes through point B, it will show higher probabilities along the way the photon passes through it. Eventually the photon will pass through point B and will continue it's way towards a point C. At some point, the wavefuntion of point A will become neutral again, showing 0 probabilities for its own coordinates and all its spatial surroundings.
Now let's combine this with gravity and GR. Lets say there is a huge gravitational mass at point B. Point A is "empty", but still inside the huge mass's gravitational field. So the huge mass at point B will have a gravitational effect on point A. How? well, the wavefunction at point B will not be neutral, since the effect of the huge mass at point B will have an effect on point A too! It will change the wavefunction at point A too! What will the wavefunction at point A look like? It will show higher probabilities in the direction of point B, where the huge mass is! And lower probabilities for its own coordinates, and in the other direction (not towards B). So how does gravity work then if we combine GR and QM? Lets say a photon is arriving from point C, which is even further from the gravitational mass.
As the photon makes its way to point A, it should just pass through as in the example before, but it will not! Why? Because in the example before, A and B were both outside any gravitational fields, and had neutral possibility distribution values for their own coordinates and their spatial surroundings too. But now, there is a gravitational mass at point B, that affects point A's wavefunction too! So as the photon wants to pass through point A, it enters into the wavefunction of point A, which shows higher probabilities towards the direction of point B, the huge mass.
So as it passes through point A, its own wavefunction (3D or 4D matrix of ditribution of possibilities for point A's center coordinate and its spatial sorroundings) will combine with the photon's own wavefunction (thats already in QM, just another matrix of ditribution of possibilities for the photon's actual coordinate and its spatial sorroundings). So as the two matrices combine, the wavefunction for point A will change the direction of the photon as it passes through, just like GR predicts. And just like QM predicts, it will all be described by the combination of wavefunctions, and distribution of probabilities. The QM's current wavefunction will also stay in tact since the photon will keep its own wavefunction too.(that should look like a momentum vector, showing higher probabilities towards its target direction) Is that a possible solution?
