¿Real or false this theory?
Hello friends of steemit, as many of you already know, I am an archer and for today I bring you a theory which many consider as useless or baseless but which in turn is quite interesting to read and which attracts attention. It's about the Big Crunch and the theory of the end of the universe, I hope it's to your liking.
¿It sounds crazy not?
Since the beginning of our universe this has been in constant expansion, thanks to the Big Bang today you can breathe, today you can run, more, I tell you that thanks to the Big Bang you are reading this today. This explosion was so catastrophic that I create stars and planets, so much so that until now, since more than 13,500 million years ago it is still in constant expansion and creation. If it sounds crazy but that's the way it is.
¿What would happen if...?
Imagine that at some point in the life of our universe this speed is lost, its constant expansion slows down and suddenly, it contracts at an unimaginable speed causing galaxies to collide with each other, turning the universe totally hot and compressing it all in one just point, this catastrophic event is termed as the ’’Big Crunch’’.
Great Implosion:
During the twentieth century some cosmological models considered the universe as a closed space, that is, with limited dimensions and, therefore, with a total mass also limited or finite. This led scientists to think that in a distant future, the second phase of the universe would be the contraction of it, where all the star bodies will accumulate with each other and the density of our universe would increase drastically (the opposite of what happens today).
This theory is known by several names, some call it the theory of the Great Collapse, the Great Implosion, the theory of pulsations or simply the Big Crunch. This theory talks about the contraction of the universe, which is a process that is sometimes seen in some stars of the universe.
¿You can imagine something like that?
Some scientists even thought about a second Big Bang, the universe when contracting to the maximum its internal mass will be very dense and this would cause another great explosion causing the process to repeat itself, this being a circle of infinite expansion and contraction.
Now imagine that this was so, maybe you already read this, maybe you read it in another way, maybe before you have died thousands of times, maybe you are just living your life just like you have done in other occasions and without knowing that it will continue infinitely, perhaps this process has been repeated endless times and we do not know it.
Now, to reality:
The theory of the Big Crunch tells us that this process of contraction will happen in about 20,000 million years, but the reality of today is another friends.
Currently this theory has become totally obsolete by many scientists in the world, because by observing the stars, they present the so-called redshift showing that the universe is expanding rapidly, this was discovered at the end of the year 1990, where they demonstrated by means of supernova observations that the universe was not only constantly expanding, but that it was accelerating faster every time.
¿What is the cause of this constant expansion?
Scientists have discovered that in the universe there is an energy causing the acceleration of space-time, this energy is invisible to the eye, that is, it can not be observed directly, so it has been given the name of Dark Energy.
The discovery of this energy has caused many cosmologists to abandon the idea of an oscillating universe, that is, a universe with an infinite process of expansion and contraction. At the moment this idea is considered totally obsolete by some scientists since NASA has obtained information that supports the theory of the continuous expansion of our universe.

This last theory is not the ideal answer, for as the universe expands, we will lose sight of the furthest glaxies, then our neighbouring galaxies and then, as our own galaxy expands, we will be left on our own.
Also, dark energy does not exist on its own - dark matter is also fighting to pull us back
I'll wait for a better theory...
PS: If you want to pay for self-voting (I am not against it) it is stupid of you to do so immediately upon posting. Why would any of us want to vote for you when you already have a 100 votes?
