Is everything in the universe arranged? Einstein may be right
The essence of the rapid development of human civilization is the progress of "science". Correct knowledge can help a civilization to make continuous progress. Many civilizations have been bred on the earth, but most of them have disappeared under the wheel of history. A few of the civilizations that have survived today have also suffered the baptism of war and cultural changes. Generally speaking, human civilization is less than 10000 years old In the meantime, so much brilliance has been created to prove the potential of human beings.
With the gradual development of human science, the problems that human beings need to solve are not reduced, but more and more. The original human beings only need to think about the problems on the earth, use science and technology to change the environment on the earth, so that the earth is more suitable for human survival. But with the progress of science and technology, we found that there is a broader space outside the earth.
People once believed that the earth is the center of the universe, or the sun is the center of the universe, that is, "geocentrism" and "heliocentrism". Although these two views are wrong, the concept of "universe" has been preliminarily answered and studied in these two views. Moreover, the viewpoint of "heliocentrism" has already made certain conjectures on gravity and pointed out the major lines Stars move around the sun.
However, with the development of cosmology, the study of the universe is more and more in-depth. We found that the solar system is not special in the universe. There are countless stars like the sun in the universe, and many stars are bigger and brighter than the sun. Rock stars like the earth are not rare in the universe. At present, scientists have found many very similar to the earth Planets, they all have the potential to become human colonies in the future.
"The more you know, the more problems and difficulties there are." once upon a time, human beings only need to think about how to "live" and "live better", but now human beings have to think about "what is the universe?" "The meaning of human existence", these difficult questions, the increase of knowledge did not bring happiness, but brought us a lot of trouble.
Human cognition of the universe is mainly based on the advancement of physics. The study of ancient Greek philosophers is the initial germination of physics. After Galileo created the system of modern science, mankind officially opened the door of "science". Then Newton brought the system of "classical mechanics" to the world. Although from the present point of view, there are some loopholes in classical mechanics Classical mechanics has played a great role in human's correct cognition of the universe. The concepts of gravity and inertia are deeply rooted in people's hearts and improve the overall cognition of human beings.
At present, most people's view of the universe only stays in the perspective of classical mechanics. This is because classical mechanics is closer to life and does not violate our common sense. However, science can not always stop on one theory. There will always be new theories to replace and overturn the old theories. In science, there is no "eternal truth" in science. With the deepening of research, there will be no "eternal truth"“ Everything is possible. ".
So, what are the limitations of Newton's classical mechanics? We know that if the two pillars of physics are "quantum mechanics" and "relativity", one is to study the micro world, and the other is to think about the space-time changes under high-speed conditions. In these two cases, classical mechanics will expose great limitations, so classical mechanics is only applicable to the macro world and low-speed state.
Because our life is very far away from the speed of light and the micro world, many physical theories are "against common sense" in our view. For example, the fastest speed of the universe is "the speed of light". It is impossible to have a speed faster than the speed of light. Any speed and the speed of light can only get the speed of light. Moreover, when the speed of light is realized, the concepts of "time" and "space" will be relative In classical mechanics, time and space are assumed to be absolute. Therefore, classical mechanics has great limitations.
It can be said that Einstein's research has overturned the status of classical mechanics in physics. People have a deeper understanding of the universe, but more problems arise. There are contradictions between relativity and quantum mechanics. The two theories can not explain each other. Even the cosmology in the two universes is completely different. In quantum mechanics, everything in the universe is random and everything Everything depends on probability, but Einstein believed that everything in the universe is "designed", and we can use data to calculate any answer.
"God won't roll dice" is Einstein's famous saying. Many people think that this is the evidence of Einstein's attack on quantum mechanics. In fact, Einstein is willing to admit that "uncertainty" is indeed the intrinsic property of the universe in the micro world, but Einstein suspects that the "indeterminism" of quantum mechanics is indeed the intrinsic property of the universe, but this phenomenon also points out that in the micro world, "uncertainty" is indeed the intrinsic property of the universe In today's quantum mechanics, there are still more profound theories that have not been discovered by human beings.
Einstein also said that "everything is decided", which is the same as God can't roll dice. It is not attacking the current physical theory, but clarifying his own views on the universe. Einstein's view of the universe is "mechanical cosmology". The universe is like a mechanical clock. The energy of the big bang of the universe provides an almost endless force to this clock, So that the clock can go on, the second hand per second falls, the next second everything is decided.
But the universe view of quantum mechanics is not the same. In quantum mechanics, everything in the universe is "indecisive", just like God threw everything at random with a dice. Obviously, Einstein did not approve of this view of universe. Einstein spent his later years to find a unified theory and prove his view of the universe. Unfortunately, even Einstein was such a day I didn't succeed.
Can human beings really find the theory of "great unity"? Perhaps in the future, now that mankind has experienced hundreds of years of rapid development, it needs time to digest and accumulate in order to breed a more correct theory.
