Nebula Theory – Studying the solar system and everything in it is endless. The presence of the solar system itself is an interesting phenomenon that makes many people wonder how it was formed. Discussing the ranks of the solar system is inseparable from all the theories including the nebula theory.
Have you ever seen clusters of stars in the sky that at first glance look like colorful clouds? If you go to a place with low light, such as in a field, on a wide savanna and use a telescope, you may have seen clouds like this.
The clouds between these star clusters remind us of the nebula theory, which in Latin means cloud. So what exactly is meant by this nebula theory?
Before going into details about the nebula theory, you need to get acquainted with the theory of the formation of the universe.
Theory of the Formation of the Universe
Astronomy explains the theories of the formation of the universe which also include the nebula theory. So how did the universe form based on the science of astronomy?
Without us realizing it, we, who have been busy with our daily activities and learning everything, are all limited to knowledge on the earth we live in. In fact, if you want to take a wider view of our vast earth, this is only a small part of the solar system and even the universe.
Have you ever thought about what the history of our solar system really was like long ago? What’s in one solar system, and what’s in another?
When discussing outer space and the solar system, maybe at a glance what is in the shadows is scenes from science-fiction films such as Star Wars, Guardian of the Galaxy, ET and the like. Of course, these stories also appeared not because of the inspiration of natural phenomena and also theories of the formation of the universe which have been a secret since ancient times.
Scientists and astronomers have been observing everything in outer space since time immemorial. Because of this, various theories have emerged to clarify and provide a common thread for all of our current questions.
In astronomy, there are a number of theories regarding the process by which the universe and its contents were formed. These theories can be interrelated and some are contradictory, but all of them are believed to be used as a reference for future learning.
Steady-state or steady-state theory believes that the universe exists without beginning and also without end. This means that nature has just been formed without any phenomenon and this theory also assumes that the universe will never end.
This thinking is also based on monitoring celestial bodies which have not changed in the past thousands of years.
This may be inversely proportional to what most people believe about the end of the world. However, that’s how a theory put forward may not always be in line with other sciences.
Today, since the 20th century this steady state theory is no longer used, given the advanced technological developments so that scientists have found evidence that is considered much more concrete.
At this time scientists believed that the universe was formed through the processes that exist in the latest theory, and not suddenly exist without a beginning or an end.
The Big Bang Theory
Ever heard of the big bang theory? Or often called the big bang theory. Based on the big bang theory, this explains the beginning of the formation of the universe as it is today because of a big explosion that came from an atom that was so dense that it was even too dense.
Due to the high heat energy and atomic density, it eventually created a very large explosion which scattered the pieces into all the material in this solar system.
This theory is also supported by the existence of Hubble research evidence, a scientist who discusses this theory. In his research it was proven that there is a red shift of galaxies in the microwave cosmos.
Some of the light elements in galaxies are getting bigger and bigger so that it is called galactic evolution. Predictably, this can happen because of the growth of gravity from the standard theory. This further emphasizes that there is a possibility that the universe was formed through a big bang.
For observers of the solar system, or for those of you who are interested in discussions about astronomy, you may be familiar with hearing the term nebular theory in your ears, because this theory is the most widely accepted by scientists and scientists .
The term nebula itself also means cloud or also means fog which was also coined by a scientist in 1755, which explained that the solar system was formed starting from a large amount of gas such as a cloud or fog.
Most of these clouds or fog come from hydrogen gas which has very hot temperatures. A rotating cloud or nebula that forms the sun and other planets in the solar system.
The Formation of the Solar System Based on the Nebula Theory
The nebula theory itself has many versions according to the research and conclusions of previous scientists. The following is the theory of the formation of the solar system presented by scientists based on the nebula theory.
Nebula Theory According to Kant
Kant revealed that the formation of the early solar system came from a nebula or cloud that rotated slowly and was attracted by gravitational forces. It is this gravity that eventually forms, bit by bit, to agglomerate and harden into the composition of our solar system.
Nebula Theory According to Laplace
Kant’s theory is further strengthened by the income from Simon Laplace, a mathematician and astronomer. Laplace explained in more detail about the role of the nebula theory in the process of forming the solar system.
Based on Laplace’s discovery, the nebula theory is a creation of the universe starting from the sun. The sun starts from a ball of hot gas that rotates centrifugally or spins outwards quickly.
Matter and gas that were on the outside of the ball were thrown away and cooled to form a planet. Meanwhile, the core hot ball was getting hotter and forming the sun.
Nebula Theory According to C. Von Weizsäcker
When Kant and Laplace had explained this nebular theory, in the 20th century a German scientist also voiced his own version of the nebular theory. According to him, in ancient times a large layer of gas in the form of hydrogen and helium was found.
Some of the gas is outside the sun’s equator and the rest just disappears. The pressure from the sun’s heat energy then makes this gas leave the heavier elements and collect in one mass line.
A series of mass collections originating from gas also attracts solid material in outer space until it collects and condenses into a planet.
Nebula Theory Based on NASA
The nebula theory, also known as the fog theory, was explained by NASA. Quoting from NASA’s Solar System Exploration states that around 4.5 billion years ago the solar system only started from clusters of clouds and dense gas in the form of dust and stars.
These clouds rotate slowly to form a larger clump in the form of a solar nebula. The existence of gravity makes dust and gas particles in this solar nebula rotate slowly and consistently to form a disk.
After forming a disk, the nebula gets denser and denser and forms a solar core. The gas and other materials that cool around the sun’s core form the ranks of the planets in the solar system that we know as the Milky Way.
In the ranks of the planets of the solar system, there is the earth where the planet where we have stopped and lived all this time.
The Process of Forming the Solar System Viewed from the Nebula Theory
Starting from the Collection of Mist
When drawing conclusions from the exposure of previous scientists, it can be concluded that this universe was formed starting from a cluster of clouds or fog. This fog cluster is actually gaseous particles that mostly contain hydrogen and helium.
This gas is also the most frequently found on other planets, including Earth in ancient times. This large and hot cloud mass is the beginning of the formation of the sun as the center of the solar system.
The fog clusters in the form of gas rotate and rotate quickly so that they have a strong enough gravitational pressure. The rotating nebula is getting stronger and stronger, the gas content inside also causes high heat, this is what will form the sun.
During rotation, some of the gas is in the path and some is outside the path of the sun’s rotation and forms a ring around it.
Spread of Gas Beyond the Lines of the Sun
The nebula or fog that is outside the trajectory of this solar nebula eventually revolves around the sun like a ring. The gas around the sun’s ring also makes its own rotation while circling the sun.
Gas Condensed Into Planets
This nebula, which rotates in the trajectory of the sun’s rings, still has the sun’s gravitational pressure. The existence of this gravity makes gas, dust and objects in outer space around it attracted by the force of gravity and unite.
The nebula that comes from hot gas also cools and solidifies over time, so that at that time gas, dust, and other solid matter merges into a rotating round planet.
Like a nebula ring that is on the path of the sun to form the planets in the solar system from Mercury to Pluto before finally disappearing.
The planets that are on the outer path of the sun have the coldest temperatures, while those that are closest to the sun still have hot gases belonging to the sun.
When viewed from the process and correlation, this nebula theory is the most widely trusted because it is closest to reality. But any theory certainly has advantages and disadvantages, as well as in nebulae.
Advantages of the Nebula Theory
Through this theory it is proven successful to state that our solar system is in a flat straight line with an oval trajectory around the sun. Therefore, it is not surprising that many scientists believe in the truth of this nebula theory.
Disadvantages of the Nebula Theory
However, there are also those who disagree and think that this theory has weaknesses. James Clerk and Sir Jeans also stated that the bracelet or ring trajectory around the sun has less gravitational pressure.
In addition, based on the nebula theory, the largest size should be a planet and not the sun. While in fact the sun has the greatest mass weight.
Already Know the Nebula Theory?
Talking about astronomy with all its theories is always an interesting discussion, especially if you are really interested in that field. So terms like big bang theory and nebula also sound familiar.
The nebula itself, as a theory that is believed by most scientists and astronomers, is the theory that feels the closest to reality. Although the explanation also varies from each scientist, we can see similarities between them.
The nebula theory still has many flaws that feel ‘odd’, but this is something that makes sense considering that the emergence of a theory is only based on research and data. No one really knows what the outer universe is like, nor does anyone know how this universe was actually created.
One thing is certain, humans continue to study the earth and its solar system throughout the year in order to get the closest data accuracy and knowledge. Therefore many of us cannot be separated from books about astronomy to study the sky and everything in it
