You have wondered how the universe originated, if it was created or simply appeared, there are several theories about the subject and in this article we show you everything you need to know about it. origin of the universe.
There are several hypotheses of the origin of the universe as well as the Origin and Evolution of the Earth in which we currently live. Some theories include the Big Bang theory, the Steady State theory, Oscillating World theory, and the Inflationary theory. If you are interested in the topic, you can also read about the origin of the universe according to other sources.
Since the human being exists, the origin of his existence has always been questioned, why his life and of course, the world in which he resides or inhabits.
In this way, for many years at different times, many students of creation science have come up with different theories that try to explain what is the origin of the universe, with coherent movements and words about the world's origin.
Today there are four theories regarding the origin of the universe, of these only two are usually approved to define how the universe was formed, these are the Big Bang and Inflationary theories.
Big Bang Theory
The most recognized reality about the origin of the universe is based on a cosmic cataclysm unprecedented in history, the so-called Big Bang. Those who defend the Big Bang say that it happened about 10.000 or 20.000 million years ago.
A massive shock wave caused all known energy and matter in the world (including space and time) to appear at that moment as all kinds of unknown energy. The hypothesis continues to support that after the total collapse, an expansion would follow, another Big Bang, and so on in a whole series of Big Bangs and Big Crunches that would also demonstrate an infinite number of the world. Although this theory does not explain the beginnings of the Big Bang itself, it is fundamental in the theories about the universe.
Inflationary Theory
In the original manifestation of the Big Bang hypothesis they had some unresolved complications. The state of matter on the date of the explosion did not allow the usual physical laws to be used.
This is how this theory was born, which would be developed in the early 80s by the American scientist Alan Guth.
According to this hypothesis, what generated the enormous explosion was an inflationary force exerted over a valuable period of time, allowing a visual zone of the world to form.
Inflationary theory distinguishes between the real world and the observable world. This observable world is the one populated by humans and is smaller than the real world. Furthermore, this theory also helps to understand the infinite universe.
Cosmic inflation manifests itself as a considerably dense, hot particle and has all the energy and mass of the world, even though it is smaller than a proton, it breaks out in a propagation that continues to exist in the millions of years that have elapsed since that moment. .
Steady State Theory
The Steady State prototype was proposed in 1948 by Herman Bondí, Thomas Golf and Fred Holyle. Bondi and Golf showed a philosophical controversy, invoking the so-called "Perfect Cosmological Principle" where the world, also necessarily homogeneous, shows the same appearance at any time.
According to the Steady State theory, the cosmos has always existed. The fundamental point of this justification is the fact that, despite its propagation, the world always maintains the same density, due to the progressive creation of new matter.
This hypothesis, which was in its heyday in the 50s, has been frequently challenged by the various astronomers who support the Big Bang theory today.
Who created it?
James Jeans, in the 1930s, was one of the first to imagine a Steady State cosmology, which is a hypothetical permanent establishment of matter in the world. These concepts are in turn related to the origin of the moon.
Oscillating Universe Theory
This Oscillating or Pulsating theory is a conjecture proposed by Richard Tolman that tells us that the world will be the last of many to emerge from the past, due to continuous explosions and contractions.
The renowned physicist confirmed that the cosmos did not actually have a common birth, but rather has been progressively "Creating" and "Destroying" itself, going through a phase of expansion and another of contraction (also known as the Big Crunch).
This hypothesis was dismissed with the revelation of microwaves (1965), which confirmed that the world must have been hot and dense at one time. For more information on this concept, see the sounds of the universe.
However, they have re-emerged in cosmology as a cyclical example, which manages to avoid all the manifestations that caused the Oscillating Universe theory to be discarded in the 80s.
What is Big Crunch?
The largest decrease in the size of a star (implosion) in history was what is commonly called Big Crunch, it is undoubtedly the theory that was based on the imminent end of the world in the XNUMXth century.
Cyclic Universe Theory
In the 1930s period, theoretical physicists, especially Albert Einstein, thought of the probability of a cyclic model for the world as an alternative to the Big Bang.
How old is the Universe?
The age of the world, according to the Big Bang theory, is the historical period of the universe limited by its distancing and propagation from its unique consistency in the Big Bang. The current scientists' settlement is 13,787 plus or minus 0,020 billion years.
The Big Bang
In cosmology, the Big Bang, also known as the Great Explosion, is understood as the beginning of the world; that is, the starting point is the one that created matter, space, and time. According to the cosmological model, the Big Bang occurred approximately 13800 billion years ago.
Main Astronomer of the Explosion of the Universe
The astronomer Edwin Hubble (1889-1953), was the most significant scientist of the 1929th century, awarded for his total conviction that in XNUMX he had indicated the propagation of the world by measuring the redshift of distant galaxies, this also according to the Solar System Scientific Disclosure Article.
Hubble is respected as the father of observational cosmology, and his contributions to astronomy and astrophysics spanned numerous fields.
