Dark Matter
Dark matter is a supposedly invisible dark mass that adds gravitational force to the galaxy and other objects in the universe. About 70% of the universe group is made up of elements that scientists have not been able to observe directly. Known as Dark Matter, this bizarre element emits neither light nor energy. So why do scientists think it is so predominant? What is this dark matter?
The discovery of the dark matter
Since the 1920s, astronomers have estimated that the universe contains more matter than can be seen with the naked eye. Human curiosity for this unseen dark matter has increased since then, but no direct evidence of dark matter has yet been found, with strong potential in recent years. Swedish scientist Fritz Zwicky was the first to discover this matter. He was observing the moving nature of galaxies between coma clusters. But the problem appeared in one place. He kept that the amount of mass contained in this cluster is insufficient to maintain such a delicate balance because there was a significant difference between the number of gravitational balls joining the existing groups in the cluster and the number of gravitational balls required hold the cluster.
If only the visible objects had the supply force, you would never tear the things in the cluster apart. But no, for thousands of years, they have maintained a perfect balance. The mass of the Coma cluster was much less than the required mass. It would be considered an exception if this were the case with the coma cluster only. But no! The same thing happened with many other clusters after the Fritz Juke. The problem is here.
Scientists then reported a possibility. There is something that we have not yet discovered. This mysterious thing is the root of everything. Then extra mass, extra objects are needed for this different ball. Because it is not possible to supply a ball without an object. Again, the supply of the ball is coming from one of the sources. That means there must be something extra.
We see a lot of visible matter in our galaxy. However, the amount of visual weight produces gravity in our universe. It is impossible to capture all the galaxy elements by that gravity. The number of stars in our galaxy, the number of asteroids or dust clouds. And how it is spinning around our galaxy at such a fast speed. It is bound to fall off the cater-cornered ball at any time. But the dark invisible mass is giving us this extra gravity.
Extra mass and matter are required for different gravity. Dark matter is the invisible matter that gives us extra gravity without our visible matter. And it was named Fritz Ziki. Later, in the 1960s, Vera Rubin determined the amount of dark matter, five times more than our visible matter, or about 75 percent of the entire universe. But what exactly is this dark matter is still unknown. Only we know that this dark matter is the supplier of extra gravity to our universe.
