The Universe according to Stephen Hawking
Physically limited, but mentally free to investigate the mysteries of the universe, Hawking leads us in a long and interesting discovery trip. Starting with the emergence of the universe and the birth of galaxies, the professor tells about what the Big Bang can tell us about the eventual end of the universe. He also reveals how the stars, black holes and life were created, with reference to this says that we live in the sun and we were created by all the stars, the universe is immensely old, the most surprising thing is that the entire universe was created tofrom nothingness.
The universe originated 14 billion years ago in a great explosion of space. All the energy existing in the universe was concentrated in a small point. The temperature was very high therefore there was no matter. After the explosion, the space of expand and cools allowing the formation of subatomic particles. In other words, current theories about the Big Bang predict that our local universe was born with a very brief episode of inflation. According to this vision, the universe expanded exponentially during a second fraction after the Big Bang.
This theory explains the expansion of the universe, the existence of a dense and hot past, the origin of the primary chemical elements that are recognized today (helium, oxygen, silica, iron, etc.) and also, the formation of astronomical objects (stars, galaxies, etc).
Stephen Hawking explained the most complex concepts of the universe, our universe is one among many. But the total number of universes is finite. And the multiple existing universes are similar among them. This is the final vision of the cosmos that Stephen Hawking developed in his last months before he died.
It is difficult for the human being to never ask about the origin of life or the universe, since they are essential questions in our own rational nature, this led the human being to investigate more about the universe and even know the future that he will haveThis, the answer to these questions is that the human being does this in order to clarify his doubts regarding his origin, where he came from, and knowing that we come from nothing is difficult to understand, so many have created aBeing supreme, in which they will support and leave all their problems and concerns, on the other hand, there are those who decide to opt for the path of science, this generates a great controversy throughout the world. But, for hawking, because the universe works in scientifically guided automatic polychHe separated to contemplate his work. “Did God create quantum laws that allowed the big bang to occur?”, Asks the teacher. "I don’t want to offend anyone, but I think science has a more convincing explanation than a divine creator," he says.
In addition, there are doubts about the future of the universe, we ask ourselves. What will humanity face in the future? What will be the future of the universe? It is not yet known with certainty that could happen, but you have an idea. We must know that the earth will not always be the blue sanctuary that we know since the continents are constantly moving and it is said that in 75 million years they will have all concentrated to the South Pole, nobody knows if the Earth could then be habitable then.
For anyone it is a secret that Stephen Hawking tried to understand the world through physics. However, it was never too optimistic about the future of our species. He imagined our future in a not so pleasant way, for example, he mentioned that we must seek a new home this is due to the increase of the world population and the abusive consumption of resources and energy to which we are subjecting to our planet, by saidReason, if humanity wants to survive as a species, is destined to find a second home. This is a consequence of the extreme consumerism of the human being. Climate change, tree logging, pollution and other factors caused by man are being determinant for a crisis of enormous proportions. Man is the greatest murderer of the Earth, he is a self-destructive and is aware of what he is doing, destroys his magnificent habitat and the creatures that inhabit this. Ends with plants which are the source of life, food and medicine, without feeling remorse. Water, sustenance of life, disappears, rivers, seas or dry. The oceans receive large amounts of liquid and solid waste daily, garbage from cities, this and much more do human beings day after day.
Returning to the theme of the origin of the universe, many human beings still believe in anthropocentrism, believing that we are the center of the universe, this is linked with the religious idea of the divine essence of man. But we really believe that we are the center of the universe when it is already known that what we can really see (planets, stars, asteroids, galaxies) forms less than 5% throughout the universe, in addition we also know that what cannot be seen asDark matter and dark energy make up 74% and 23%. This helps us realize that we are something tiny compared to everything that the universe has, as Hawking said “we are a breed of advanced monkeys on a planet smaller than an average star. But we can understand the universe, that makes us very special ”, so it makes us ask ourselves if it really is worth complicating or distressing so much for a problem that is presented to us and that we know that it has a solution, it should also be noted that the problems it hasThe planet Earth is currently very serious. The universe remains and will be a dangerous place while the asteroids exist, such as the threat on the planet earth from the asteroid apofis (called by the God of darkness and destruction), it is said that on April 13, 2029 it islikely to rub the earth. There is also the mangatan asteroid, this reaches the land every 100 million years, the last one was 65 million years ago and it is said that he could have been responsible for the extinction of dinosaurs.
But apart from this, there is something called "black holes", they have a fundamental role in the formation of galaxies, how are they formed? When a giant star comes to the end of his life, he becomes unstable and suffers violent seizures when he begins to agonize, when the fuel runs out, he begins to shrink becoming more and more dense and the explosion cannot be stopped, here the gravity actsAnd it shrinks the star, because of this the core temperature increases to one hundred billion degrees, the upper layers of these stars explode large supernovae, but inside the nucleus becomes a gravitational well, it is compressed andThus the black hole is born.
These research carried out by scientists have brought many consequences to humanity, both bad and good, is artificial intelligence, according to Hawking this threatens the future of humanity, since smart robots “have the ability to perfect themselvessame and be more cunning than all of us, ”said the scientist in an interview with the North American HBO channel. On the other hand, scientific and technological advances bring benefits for people such as comfort, better health, education, more effective communications, but sometimes these advances can be harmful to society and the environment, such as pollution andContinue to traditions and religions, because of this people adopt various attitudes against scientific and technological advancement.
Personally, the video has opened my eyes, has made my perspective in front of the world different, realize that not everything revolves around mine, has caused more doubts about the universe and life, not all have respondedAnd I must question myself that "we were created from nothing". I have realized that physics explains reality, since all existing laws (gravity, relativity, quantum physics) and some other rules can explain everything that happened or will happen in the universe. He also taught me that there is no reason to live a moment of anguish or stress becausethat black holes are not as black as everyone believes they are. They are not eternal prisons, as they believed before. If you feel as if you were caught in a black hole, do not despair, then there is an exit ”.
I must add that my concept of life and creation is in an internal debate among themselvesgone producing through the predecessors (creationist or evolutionary theory). In the same way, after having seen the video and investigating a little more, I feel that I need someone to support me and I know that I can feel relieved and confident because everything would be fine.
Finally, even more doubts arose in me, I sincerely do not know when they will be answered, if we really were a work of God? I know that Hawking talked a little about this, but I am not entirely convinced, since each person sees the world in his own way and I do not want to rule out the possibility that a God created us, I also wonder if, is the universe infinite? Although it is said that the universe has a horizon, is there life on other planets? How can the universe end?
In conclusion, this video teaches us a little more about how amazing our universe is, it teaches many more things that I could not mention, but that they are certainly important to know and apply them in our daily life. Our mind opens more about reality, and opens our eyes on how we are currently, is the example of our planet Earth and where we are taking it. From planet Earth we get all our foods, in addition to that it is the place where we live, and in recent years we have overexploited the ecosystem causing irreparable damage to the environment. If we continue as we are going, we will soon have destroyed our habitat and it will be difficult to survive future generations.
