Origin and the end of known Universe. Disclosure 32
The beginning and the end of known Universe, as the origin and beginning of life in Earth, both have always been so attractive to Humanity. Recent progress in creating new instruments for subatomic tests and space telescopes have given science the choice to go forward with knowledge concerning to known Universe’s beginning and to make some theories about its ending.
Although in science phenomenon denominations have Greek and Roman influences, and Arabian and Hebrew also in all concerning to great events, in this case we have English words to describe, like Big Bang or Big Rip and Big Crunch when we talk about the beginning and the end of known Universe hypothesis. Big Bounce is also an actual terms to theorize about cyclic situation of beginning-end-beginning-end of Universe.
Big Bang terms are used concerning to Universe’s origin and evolution and specially referring to the moment when Universe visible expansion took place. Physical evidences we have about that, like microwave bottom radiation or images caught by Hubble space telescope. Recently the evidence of the existence of bosons and their capability to transfer mass to particles, it completes physical evidences about Universe’s origin. So, visible matter and luminnic energy both are such essential things to know all about the origin of Universe. It is accepted that it was about 15.000 million years ago when Big Bang happened.
Once the Universe is already made up and expanding itself, science attention has been paid to the destiny of it. And so, researches in dark energy nature are needed. Two theories have been worked out: Big Rip and Big Crunch.
Big Rip proposes that expansion of Universe will go on until relationship between pressure and dark energy density imbalances on behalf of that last one. In that moment gravitational repulsion will destroy all objects in the Universe, separating ones from others by losing gravitational cohesion. It’s calculated that nowadays matter represents 23% and energy 77% in the Universe. Because of that it’s accepted that Big Rip may occur within 20.000 million years, and so, Universe’s life will have been about 35.000 million years old.
Big Crunch hypothesis is opposite to Big Rip one, and theorizes that expansion of the Universe will cease and all elements in the Universe will be together again coming to an initial point, they will compress, condense in one energy point, the same one as before Big Bang had happened. In an hypothetic Big Crunch it would be possible to observe displacement to distant galaxies blue, temperature of the Universe and cosmic radiation both would increase until all objects would be destroyed.
In the end, Big Crunch hypothesis enhances Big Bounce theory which says that once the Universe gets into a final position, the same as Big Bang position, a new Universe may appear.
Nowadays both Big Crunch and Big Bounce theories are losing support after the evidence of dark energy existence which is not related in none of them.
This fact gives the most truthfulness to Big Rip also called Big Freeze. However, experience proves that new discoveries may enhance Big Crunch hypothesis or create a new one from adding both parts of each other, according to the end of Universe
