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.

Big Bang

Big Bang:

The start of everything in the universe, we believe that universe started with a Big Bang, an explosion that started from size of an atom and grew up to be our universe that is so large that we can't even compute, no matter how much we find we always have more.

It all started with Edwin Hubble who saw the galaxies are moving away from each other, they were red shifting, thus we imagined them to have started from a single point at one time, this makes perfect sense why they are moving away. We also found cosmic background radiation, a tell tell sign of a bang that happened long before approximately 13.7 billion years ago.

This gives us clue that our universe started from a single point and is expanding, but recently we found a problem, we found that galaxies are not only moving away from each other but actually speeding up, we couldn't explain how this could be happening so we added another factor in it and called it dark energy, dark because we haven't got a clue about it, energy because its pushing the universe apart.

Though we haven't found this energy and this isn't ripping galaxies apart, in fact we see that our galaxy's black hole is getting more massive by consuming more stars, so eventually our sun in whatever form will also be consumed by the same, thus galaxies will get smaller but we are still going to be very very far away from the other galaxies around us. That is actually a contradiction, how come dark energy operates outside the galaxies but doesn't have effect or actually has reverse effect inside the galaxy?

Let us imagine the situation in a different way, let us see why we could be moving away from other galaxies when we know that at start of it all, we were moving much faster, we slowed down and now we are speeding up again. What does it seem like?

So it's a U chart, why did we slow down? Did dark energy started after a certain point? I could give amazing reason for this that would need amazing calculation and fantastic new concept that would simply boggle the mind or I could say something so simple that answers it, without the need for dark energy and I'm sure I'll will be ignored, because for some reason everything should have weird answers that doesn't make sense to 99% of the world then you are scientific.

I could just tell you here but I'm going to write a bit more, remember Shoemaker Levy 9 comet that crashed into Jupiter? Remember how it broke into many pieces before it crashed into Jupiter? So I ask a question why did the comet broke up? I'll give answer to this as well, that happened because the front end of comet experienced a higher gravitational pull compared to back end, if Shoemaker Levy might have been spinning it might not have broken. Now imagine you being on part of the comet that was right in the middle, you could see the part that is in front of you as you travel and you could see part that is behind you, now imagine if you couldn't see Jupiter.

You will only see that part in front of you is moving away faster and part that is behind you is going away from you as well and speeding up, but it's not that it's speeding up but you are moving toward Jupiter faster.

It will give you impression that comet trail is expanding, we have a similar situation, we are actually moving toward an object the galaxies ahead of us are feeling more pull this they are moving faster and galaxies behind us are feeling less pull (compared to us) thus they are moving a bit slower but for us we feel everything is moving away at an accelerated speed.

We are already in a Big Crunch, no we are not moving toward empty center, we are actually moving toward the object that our universe was part of, very very massive, we were like a small blip that started approximately 13.7 billion years ago, this is why when we started the speed was higher, it actually went to 0 and now we are moving back with higher speed and its speeding up.

If a small body like Jupiter could have such enormous effect on Shoemaker Levy then this unknown object must be way too powerful.

That gives you exact U curve, this will also give you expanding sensation and it would tell you that we are moving away but actually we are moving toward the most massive object there is.

You could say why isn't it breaking our galaxies or stretching it? That is because its still very far away and dark matter is holding the shape till we reach very close to it, that will be the end of it all and we don't know that day, but we will see galaxies disappearing and we moving into empty space, when will it all end is unknown because when we really approach close to it, we would be traveling much faster than speed of light and we will not be able to calculate our position compared to the object, we will hit its surface even before we see it.

Accelerate Expansion of Universe


Accelerated Universal Expansion without need for Dark Energy


“In physical cosmology and astronomy, dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe. Dark energy is the most accepted hypothesis to explain observations since the 1990s that indicate that the universe is expanding at an accelerating rate. In the standard model of cosmology, dark energy currently accounts for 73% of the total mass–energy of the universe.”
The above is a term coined to explain the “expansion of universe at in accelerating rate”, reason cannot be determined if universe expanded out of big bang, if it did, it should be slowing down but not only that it’s not slowing but actually speeding up and things are moving away faster and faster.
In case universe came out of big bang and expanded, it should slow down as energy that started the bang will die out and things will slow down, this explanation would work perfectly if we assume every bit of matter was used up in explosion that made the big bang possible. In this case we cannot explain why universe isn’t slowing down, but if the picture is changed a little and seen as lots of matter remained behind after big bang, the whole assumption changes.

Example:
Imagine a bubble formed on surface of water and it pops, if things are slowed down we would see bubble popping and small droplets flying off in different directions eventually going to attracted back to water surface but let us take 3 points in this pop for example.
Fastest droplet
Slowest droplet
Average Speed Droplet
Fastest droplet is going to travel the longest distance away from water surface, it will reach the maximum point, stop and move back when gravity acting on it has slowed it down to speed 0.
Slowest droplet isn’t going to last much time, just after it goes up, it will slow down to halt and move back even before fastest droplet has reached half height.
While average speed droplet is in the middle, started fast and has almost stopped moving.

Now assuming we are on average droplet while it has stopped moving or slowly moving back, we see that fastest droplet is moving away faster and faster, distance is increasing so we accelerated rates, the slowest droplet is moving back going away from us, we see it moving away too at an accelerated speeds, the distance between us is increasing.
This is the simplest explanation that can be given for expansion of universe at an accelerated rate.
