The dust cloud theory is a theory which assumes that solar system comes from gases as well as clusters of dust that are in space.
Thus, the theory is known as The Dust Cloud Theory (the theory of dust clouds). This theory was put forward by Von Weizsaecker in 1940.
Then perfected by Gerard P. Kuiper, Subrahmanyan Chandrasekhar, and others in 1950.

Assumptions Regarding the Dust Cloud Theory
The theory begins with the assumption that in this universe there are many scattered clouds of the same type.
One of these clouds underwent a process of compression that occurred about 5 billion years ago.
As the compression process takes place, the dust particles are attracted to the center of the cloud, forming a spherical clump that begins to twist.
With time, the gas lump began to flatten and form a thick disk in the center.

Meanwhile, the edges are getting thinner. In the middle, the particles will press against one another.
This results in heat generation and then turns into incandescent. That change is the beginning of the creation of the sun. While on the edge or outside, experiencing a very fast rotation.
As a result, it splits into several smaller clumps of dust and gas. The small lumps of dust and gas also undergo a twisting process.
In the next process, the blob freezes and becomes planets and satellites.
Gerald concluded that the formation of the solar system came from dust and twisted clouds.
History of the Dust Cloud Theory
Astronomers believe that the beginning of the universe began with a huge explosion.
The big bang is known as the ‘Big Bang’. The occurrence of this explosion is approximately 13.7 billion years ago.
This is evidenced by the presence of microwaves and a number of meteorites in the sky. The dust cloud comes from the explosion over hydrogen.
While this hydrogen is the first element that is formed when dust clouds experience condensation. While rotating, then become solid.
By the time the dust cloud reaches a temperature of 20 degrees Celsius, helium from the nuclear reaction begins to form. Then it turns into a helium atom.

Meanwhile, some of the other helium turns into energy in the form of rays infrared.
The next theory is related to dust clouds, the change in form that comes from hydrogen follows a formula for energy changes, namely E = mc2. This formula was proposed by Albert Einstein.
Thus, we get a result that the amount of energy emitted will be proportional to the mass of the hydrogen atom that undergoes change.
In the next process, the stellar wind exits the poles of the dust cloud. Then it will spread and then remove the dust that is around the dust cloud.
That way, the remaining dukhan forms a disk and eventually turns into a galaxy.
Next, the stars and the gas that is formed will fill the part in the galaxy. So, produce a sheet structure (filament) as well as a cavity (void).
The researchers concluded when universe what we know today resembles cotton. There are parts that are filled and there are parts that are empty in them.
Some experts also put forward when the dust cloud theory has similarities with the nebula theory if viewed from the process.
The essence of the mist formed incandescent gas and swirled as it is now. Kant and Laplace are experts who put forward the theory of the nebula.
Weaknesses of the Dust Cloud Theory
Just like other theories about the solar system, this theory also has its drawbacks. Here are some of the weaknesses of dust cloud theory in the solar system.
The first weakness of the dust cloud theory is that there is no explanation for why the satellites are smaller. But in the end it doesn’t get sucked in planet another when twisting occurs outside the disc.
The next drawback is the lack of an explanation of the origin of the cloud dust referred to in this theory.
In this dust cloud theory, there is no explanation regarding the difference in the direction of rotation of the orbits in the solar system that are passed by several planets. (R10 / HR-Online / Editor-Ndu)
