Problem with relativity

Issue with general relativity:

General relativity states that we see motion relative to other objects but light does not move in relation to any other physical object, it moves independently to everything moving with constant speed relative to space time (an imaginary field). Numerous experiments have been conducted to prove the concept to be right and successfully so, though my point here is to talk about the motion of light through space and time.

If time space is some how related to other objects around it or is totally independent of these objects is not clearly defined.

When objects such as our galaxy or sun move in this field of space time it has to move in 4 different ways, if there is some other ways that I have not taken into account, please let me know, I'll try to incorporate them.

It moves totally independent of objects in it, meaning it has no relation to it massive objects like black holes and starts, space time would be stationary while earth moves in it.
It move with massive objects, that means its locked into position and moves with the objects in it, this is a dynamic background where space time is dynamic.
Space time moves and expands as universe expands, position of space time is totally independent of position of earth or other massive objects.
Space time doesn't change for galaxies but its expanding between galaxies, while being totally stationary within the galaxies where we do not see expansion.

If there are more scenarios please advise, it will be a great help.

1. This works great if universe is static but this concept doesn't work if universe is dynamic and moving, which it is. In a static universe light on earth will have little effect in relation to speed of Earth moving through time and space around the Sun, the speed of Earth around Sun is around 30 km/s. If space time is static, light moves relative to it, while Earth is moving in the same space time. Speed of light is approximately 300,000 km/s that means if light travels 300,000 km in space and time, Earth travels 30 km in same time. That means 30 / 300000 = 0.0001 km = 0.1 m. So deviation during evening and morning around the Sun will be 0.1m. Experiment will be very simple, point a laser at a point at mid night the point should move down 0.1m in morning and up 0.1m in evening because of space time as light travels through space time and has no reference to Earth or Sun or anything, this is possible only if space and time is static and not moving, while everything else moves in it, the problem is even worse if you take speed of Earth through space time while universe expands of around 600 km /s (referential not absolute).

As background is static and Earth is moving light moving in that static background will move in a straight line, in one second earth would have moved 30 km and thus there would be 30 bent seen but as we are calculating only for 1 km we should see 10cm bend. This is worse if we go at higher speeds of galaxy moving at 600 km/s where we should have a difference of 2 meter for every km light travels





2. Another option is that everything is relative to space time, thus space time moves around the Sun with other planets, if that really happens it will be really twisted. This is a bigger problem because now it becomes a problem to explain that how come we see everything moving but space time is referenced to position of the objects in it, when light is not relative to other objects. Thinking logically light would bend in space, thus if laser is pointed at an object in space it will hit the object doesn't matter where it moves, the whole concept becomes very confusing and illogical, so that doesn't work at all.

It's like space time is twisted and in a very bad way, light would never travel in straight line, it will always turn based on the twist in the space time.


3. We could consider that space time is totally independent of Earth and other heavenly objects and expands with the universe, light wouldn't bend but instead of light would expand as space time is expanding at speed of 600 km/s. Truth of this idea could be tested with simple experiment where if you have two lines in space for every km these lines should go away from each other 2m. This would happen because two beams of light in an expanding area will go away from each other. We could see same if we draw lines on stretching surface and while we draw lines with a guide we stretch the surface.


4. We could think it in another way too that space time isn't expanding for galaxy itself or inside it but only outside the domain of these galaxies, thus light wouldn't bend against the movement of galaxy but its expanding between the galaxies, if that stands true we would have totally different visuals from other galaxies compared to stars in our own galaxy. We would actually see a refracted images of these galaxies and not only that because our visual field would really start from the point where galaxy (and space time) isn't expanding we would see a very large image of other galaxies, we probably do and these galaxies are really far but we see them nearer actually the distance is so much that these galaxies have to be very far away, impossible to see. This doesn't work either, so we could safely say that there is no space time in which light travels.

Light is relative and travels with reference to certain object our best bet is to go back to drawing board and see what people have said in the past, light travels through Ether, which now could easily be tagged as dark matter.
