dung pham Posted May 6, 2018 Posted May 6, 2018 (edited) Electric fields, magnetic fields ... exist in two opposing states: · charge (+) and charge (-) · north pole and south pole Gravitational field has something wrong because it only has gravity without repulsive forces. Let us now assume that the "gravitational constant G" is not invariant by distance. It can take negative values, positive and zero. · When ( G < 0 ), it will have gravity · When ( G > 0 ), there will be thrust · When ( G = 0 ), there is no force At the point where G = 0 is called the the equilibrium position. There are two types of equilibrium position: sustainable ( R2) and non-sustainable ( R1 , R3). · At R2: If the moving object moves away from M, it is pulled in. If it goes in the direction of movement near the M, it will be pushed away. As a result, it simple harmonic motion around the equilibrium position R2. The amplitude of this simple harmonic oscillation can be very large. · At R1 and R3, if the object deviates from the equilibrium position, it will be pulled in or ejected. Spoiler Spoiler The connection of objects in galaxies is similar to the bonding of atoms in the metal network. Thus, galaxies can exist in all different shapes. In the distance from M to R1 is equal to L1. G<0 and R1 are said to be boundaries of Oort cloud because matter outside of R1 would be pushed out of the solar system. So: R1 = 1.ly Is gravitational constant a constant? All experiments to find this constant are done at very small distances. This is a shortcoming in science. At great distances, humans rely on the motions of planets to find G. The law of Kepler 3 shows us that G is not a constant: Recently, Pioneer 10 and Pioneer 11(Pioneer anomaly) show that G increases with distance. Absolute values of G tend to increase with distance. G decreases to zero and changes the sign (negative, positive) when passing through the equilibrium point. (See the illustration below). The gravitational constant G is forced to increase to serve the following problem: It is the energy conservation of gravitational waves. If : L1 = L2 = L3 =... = Ln, then G is forced to rise too fast. This is unreasonable. Therefore, L must also increase along with G. I have an assumption that: Ln+1 = K . Ln with K > 1. I'm leaning toward the plan : K = 3 “This is just a guess, because most of the objects at distance 3ly have a direction of motion away from the solar system” As G increases with distance, all gravitational calculations will no longer be valid. Gravity is much bigger than what we think. This is dark matter. Gravitational field is not only gravity but also repulsive force. This is dark energy. Spoiler Edited May 6, 2018 by dung pham

There are galaxies where dark matter accounts for 99/100, but there are also galaxies with no dark matter. Calculating it is a very complex matter. It requires a lot of data, effort and a powerful computer. All of these I do not have. My article is just in the process of being formed.

Endy0816 Posted May 7, 2018 Posted May 7, 2018 You can't discount evidence just because it doesn't support your belief. Papers were put forward by several groups anyways.

You mean the scientific methodology that is responsible for what we know of today and also responsible for showing up unsupported hypothetical nonsense that chooses to ignore evidence to the contrary for what it is. To further this point. In science, theory does NOT mean a random guess, nor a hypothesis, nor just an idea. A theory is the pinnacle of our understanding, well tested against the evidence, numerical and precise. Saying something is just a theory is similar to saying, "what do you mean he's not coming to work, he's only been decapitated".
dung pham Posted May 7, 2018 Author Posted May 7, 2018 I do not say is to reject the old theory. I just want to raise it to a new height. If the old theory was perfect, then the problem of dark matter and dark energy was explained. There are a lot of new theories to explain this. But they are far more complex and difficult to understand than dark matter and dark energy. The motion of objects in the universe challenges every theory we have. Why do you think that the sun is running around the earth and not the earth running around the sun? Dark matter and dark energy are problems that can be explained simply by thinking differently about G. The fact is that scientists use Gravimeter to measure the gravitational acceleration of the earth. But after removing the influence of the moon and the sun, it gave a catastrophic result. What do you think about this?

It's a great thing that science doesn't look for perfection, but instead looks for the best supported explanation. Hopefully you read what Klaynos posted about what a theory REALLY is, because you don't seem to understand what one is. This concept is one of the most powerful in all of science, and it's important that we use it properly.
