The scientific community has made remarkable advances in the laws that govern the universe . However, there is no single theory regarding its origin and its end. In this sense, those who dedicate themselves to the early formation of the universe tend to maintain the Big Bang theory , while those who approach its end developed the Big Crunch theory.
Big Bang and Big Crunch, two complementary theories
The Big Bang theory states that the universe is constantly expanding. This phenomenon is the logical consequence of two circumstances: in its original moment there was a great explosion accompanied by the appearance of matter in expansion by the action of heat and, at the same time, the effect of the gravitational force between the planets keeps the expansion of the cosmos from gradual way.
Consequently, the moment the expansion contracts it will produce a definitive collapse. From this will occur the Big Crunch, an English expression that can be translated as “the great creak” or “the great collapse”.
From origin to end
Expanding matter dominates the universe in a complex combination of protons, electrons and neutrons that form atoms. Then the first chemical elements are formed: nitrogen, helium and lithium. In this sense, it is believed that in the beginning the cosmos was a confused mass of matter and antimatter. This reality about the early universe could be deciphered using a particle accelerator.
On another level, the mutual gravitational attraction generates the clustering of galaxies (according to current theories, galaxies arose from the accumulation of matter in a process of fusion). Such evolution implies the permanent expansion of space.
According to the Big Crunch theory, the phenomenon of the expansion of the universe will come to an end through a definitive contraction. In other words, instead of growing, it will produce the opposite effect, that is, a large implosion in which all the galaxies will merge due to the action of high temperatures. Due to this, a large black hole will be formed, from which it will absorb all the existing matter. This theory about the end of the universe is not speculative in nature, as it is based on the observation of supernova explosions that ceased to exist after an explosion.
The Big Crunch theory is often interpreted as a circular view of cosmic time.
The Great Collapse does not necessarily mean that the universe will permanently cease to exist. In fact, some cosmologists suggest that this would be the definitive step towards a new beginning for the universe.
The idea of restarting the universe has a metaphysical dimension , as it reminds us of the theory of the Eternal Return, approached by ancient Stoic philosophers.
