Hello, friends welcome to our new article about how the universe formed. Today we will talk about the origin of the universe, the formation of the solar system and our earth, which is explained on the basis of the Big Bang theory.

How the universe formed


How the universe formed

Many theories have been given regarding the origin of the universe, but the most common theory, which is called Big Bang Theory, we will discuss in this article. Astronomer Edwin Hubble, doing research in the year 1925, found that every planet, star, and galaxy in the universe is moving away from each other. In other words, the universe is expanding continuously. This experiment helped to understand the origin of the universe. Since the universe is constantly expanding, it could be said that it must have started from a point form called the singularity, and from here the Big Bang Theory was born.

Formation of the solar system

Lighter elements such as hydrogen and helium were formed from electrons, protons, and neutrons after the temperature dropped, about 380,000 years after the Big Bang. Gradually the universe cooled down and heavier elements began to form from lighter elements. The gases present in the universe came closer due to gravity, which led to the formation of stars and galaxies.

About 4.5 billion years ago, a star in our galaxy exploded and the clouds of dust and gases emanating from it covered the entire galaxy. These clouds of dust and gases are called nebula. This nebula started gathering due to gravity and started revolving in the form of a disk around its center. Due to the extreme temperature of the center, it took the form of a star from which the Sun was formed, besides other planets were formed from the nebula revolving around the center.
