3 Most Popular Theories of the Formation of the Universe, Which is the Most Logical?
For a long time, scientists have proposed several theories about the formation of the universe. It is an attempt to answer the puzzle of how the universe actually began to form.

Has it ever crossed your mind how the universe was actually formed? The universe, with all the magical phenomena in it, certainly did not just appear out of thin air. This problem has intrigued scientists for a long time. Various theories have emerged to explain the process of the formation of the universe. Scientists compete to present the ideas they feel are the most logical. Starting from Hubble, who developed the big bang theory, Thomas Gold, with the steady state theory. And Hoyle, who proposed the oscillation theory. Interesting, huh? For more details, let's look at the three most popular theories of the formation of the universe in the world of science below.
Big Bang Theory
Some scientists try to understand the formation of the universe through the big bang theory. This theory is also known as the Big Bang theory. The Big Bang theory was first put forward in 1922 by a Russian scientist, Alexander Friedman. Then, in its development, the American scientist Edwin Hubble developed a continuation of this theory around 1927. At that time, Hubble observed the movement of galaxies continuing to move away from each other and discovered the relationship between galaxy distances.
Quoting from space.com, in general, the Big Bang theory states that the universe occurred due to a powerful explosion from a super atomic blob. These super atomic blobs have enormous heat, mass and density. The results of the explosion continue to spread and form galaxies, planets, etc., that fill the universe. The explosion effect also creates space and time.
Steady State Theory
One theory of the formation of the universe that has been popular is the steady state theory. Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle proposed this theory around 1948 by referring to the principle of perfect cosmology.
The essence of steady-state theory is the emphasis on a universe where conditions will always be the same. The universe had no beginning and will never end. According to this theory, the age and extent of the universe is infinite. During its development, many scientists rejected this theory because it was considered irrelevant. In fact, the steady state theory is considered to be the opposite of the Big Bang theory.
Oscillation Theory
Around 1948, Fred Hoyle also coined the oscillating theory. This theory is also known as the theory of expansion and compression. The essence of the oscillation theory is that the emergence of the universe came from a cycle that began with mass expanding and then compressing. On the one hand, this theory agrees with the existence of an explosion, as revealed by the Big Bang theory. On the other hand, the oscillation theory also believes in the truth of the steady state theory, which states that the universe will not end.
Based on oscillation theory, the formation of the universe began with mass expanding due to the reaction of hydrogen nuclei. When this mass expands, galaxies begin to form. The estimated duration is very long, reaching 30 billion years. After that, the galaxy that forms will begin to dim and enter a compression stage. This stage begins with the release of very high heat emissions first, and then expansion occurs. This same cycle is said to continue repeating itself without end.
These are the three theories of the formation of the universe that are popular in the world of science. Until now, scientists still believe that the Big Bang theory is the closest to the truth. However, as we know, science continues to develop. Do you think a new theory will emerge that will change your view of the mystery of the formation of the universe?
