Universe
We explain what the universe is and what the Big Bang theory consists of. Also, what are the views of its possible end.
What i? Universe?
The universe is the conjunction of everything that exists; whethe, it be ma like the planets, stars, galaxiesor or in cont,rast immaterial like energy, space or time. This is why we can affirm that the universe is the space and time in which the planets are found and their phthel laws that govern them (such as the law of gravity).
The universe, broadly speaking, is made up of interconnected galaxies that give rise to clusters of galaxies that in turn, ted to ,other groups, consequently generating a cosmic web that expands throughout the universe.
The universe has a variable extension and challenging to calculate because it can contain other galaxies. In turn, we often tend to think that the universe is static, but the reality is that it is a changing place full of phenomena.
How did the universe originate?
The Big Bang Theory defends the idea that the universe is finite and that it e an end.
The Big Bang theory is the most accepted scientific theory about the origin ouniverse’s originablishes that approximately 13.7 billion years ago all the mass and energy (of the universe) were concentrated in an extra tiny point that exploded and thus gave rise to space and time and to the set of essentiafundamentales that Together they formed matter and energy.
The Big Bang theory bases its foundations on Einstein’s general relativity theory, concluding that the universe is not static but is expanding and constantly moving. This theory also defends the idea that the universe is finite, that it has an origin and will have an end.
Will the universe have an end?
There are several theories that, after a hypothesis, explain how they believe the end of the universe will be. To begin with, we can talk about the Big Freeze model, which dictates that the continued expansion of the universe will cause (within a billion years) the extinction of all stars, resulting in a cold and dark universe.
We can also mention the Big Rip theory (or the excellent tear) that proposes that the more the universe expands, the more dark energy is generated, reaching a moment in time when dark energy will overcome gravity, breaking the balance that it is present between both forces and causing the disintegration of any matter.
Finally, there is talk of the Big Crush phenomenon that defends the universe’s contraction in a single point after its maximum expansion, giving rise to a new Big Bang.
