Hundreds of years ago, mankind embarked on the road of industrial development, and the foundation of industry was various theoretical sciences. Without the emergence and breakthrough of various theoretical sciences, science and technology would not be able to develop, and among the many branches of science, physics is the well-deserved leader.
Physics is the leader of natural sciences. From microscopic particles invisible to the naked eye, to macroscopic infinite space, they are all within the scope of physics research. The great scientists who appeared in the history of human science are basically in the field of physics. For example, Newton and Einstein have made great contributions to mankind in the field of physics.
Most of the nature of this world belongs to the field of physics, especially if human beings want to study and explore the mysteries of the universe, it needs the research and exploration of physicists. Physics is not important in the world of science, and it is the theoretical basis of other disciplines. It represents mankind’s cognition of the nature of the universe.
By studying the laws and forms of movement of matter, we begin to understand the world step by step, and to understand the universe beyond the earth. Physics is very important to mankind. It determines the hierarchical strength of human civilization. Mastering more knowledge in the field of physics can make mankind stronger faster and better explore the mysteries of the universe.
Although it has been hundreds of years since human beings have entered the era of science and technology, the true glorious period of the basic theories of physics is actually the period in the early 20th century. The beginning of the 20th century can be said to be the glorious stage of physics. At that time, the continuous emergence of physical theories laid a solid foundation for the rapid development of science and technology.
If physicists proceed at the speed of development at the beginning of the 20th century, then human science and technology will soon usher in major breakthroughs and soon become a powerful interstellar civilization. However, in the middle and late 20th century, many physicists discovered that the development of human physics seemed to have encountered a “bottleneck”, and the development speed gradually slowed down and became slower and slower.
Some friends may not understand: Since the development of physics has been slower and slower in the middle and late last century, why has the speed of human science and technology developed so fast in the past 50 years? In fact, I want to briefly explain that the slow development of physicists does not mean that the speed of technological development has slowed down. When physicists say that physics started to slow down 50 years ago, it mainly means that there are no major theoretical breakthroughs, especially basic theories.
The basic theory is the key to the qualitative change of science and technology. The various science and technology that we are applying are actually applying various basic theories put forward by physicists at the beginning of the last century from theory to reality, whether it is electromagnetic theory or relativity theory. , They affect the subsequent development of science and technology. All our current applied technologies are not divorced from the great physics theories at the beginning of the last century.
Why did physics slow down from the middle and late last century? Scientists believe that the main reason is the inconsistency of the two theories, “Relativity” and “Quantum Mechanics.”
I believe my friends all know that there are four basic forces in the universe, namely, strong resultant force, weak resultant force, electromagnetic force, and gravitational force. And these four forces have their own physical framework theory through the efforts of scientists at the beginning of the last century. But when scientists wanted to unify the four forces, they encountered huge resistance. In his later years, Einstein’s wish was to unify the four basic forces in the universe, but he did not succeed.
The four basic force theories formed by human beings can only be researched and explored in their respective frameworks, and they cannot be truly unified. This is enough to prove that the current physical theories of human beings are still incomplete and have many defects.
In order to unify the four basic forces, scientists have proposed the “great unification theory”. Only when the four basic forces are unified can they explain the nature of the universe and explain many incomprehensible material phenomena. The importance of the Grand Unification Theory to mankind is self-evident, so many scientists have joined the ranks, hoping to find a way to unify them.
We can foresee that whoever can unify these four forces will inevitably become a scientist even greater than Einstein. But until now, no one has done it. For the grand unified theory, there are only two theories still under conjecture that can be unified.
The first is string theory. The basic point of string theory is that the basic unit of nature is not point-shaped particles such as electrons, photons, neutrinos, and quarks, but very small linear “strings.” String theory unifies the four basic forces in theory, but unfortunately there is no experiment to prove the correctness of string theory.
Another theory is the “cosmic holographic theory”. This theory is even more subverting people’s cognition. It believes that the matter in the universe does not exist, and everything that humans perceive is nothing more than “information”. Our universe is an indivisible “whole” and a ” Holographic projection”.
I believe everyone knows about “holographic projection”, it is actually a kind of virtual reality technology. Although the current virtual reality technology of mankind is far from real realization, it can be seen from the current research results that once the future virtual reality technology is realized, then when we enter the virtual world, it is difficult for you to distinguish that. Is it real or virtual?
In the holographic cosmology, our universe is a virtual reality projected out, and the essence of the universe is countless information. Why do scientists put forward such a subversive theory? What kind of scientific and technological basis is there? In fact, the reason why scientists propose the holographic cosmology is mainly inspired by quantum entanglement.
Behind the macro is the micro, and the research and exploration theory of the micro is quantum mechanics. In the world of quantum mechanics, there are many phenomena that completely subvert the macro theory, such as quantum entanglement. Quantum entanglement can be said to be a major problem in the physics world. Einstein once called this phenomenon “ghosts”.
Quantum entanglement means that when two particles in a system are entangled, no matter how far apart they are, they can react instantly regardless of space and distance. This is an ultra-distance effect that completely subverts our cognition. When multiple particles interact, they will form a whole.
After forming a whole, even if the particles are separated, they are still in a state of entanglement. Even if the two particles are separated by tens of light years, hundreds of light years, they can influence each other instantaneously, completely ignoring distance and time. This speed of influence far exceeds the speed of light, not the super-light transmission in our perception.
Quantum entanglement only occurs in quantum systems. There is no such phenomenon in the macroscopic universe, but we must not forget that the macroscopic is composed of the microscopic. In theory, the macro and the micro should be synchronized, and the quantum entanglement in the micro should also exist in the macro universe. But the reality is not there. What is going on?
In this regard, scientists have begun to doubt the nature of the universe through the magical phenomenon of quantum entanglement. If the universe is a holographic projection, then it can be a good explanation that quantum can achieve instant entanglement effects regardless of distance. Because the universe itself is a whole, under the separation of the whole, everything can affect each other instantaneously.
If the universe is a holographic projection, where does the projection source come from? Scientists speculate that it may be a three-dimensional projection from a two-dimensional world. Everything that humans experience may be derived from what actually happened in the two-dimensional world. This theory has subverted our cognition, and most people still don’t want to believe in such things.
However, with the continuous advancement of science and technology, as the understanding of quantum entanglement continues to deepen, more and more scientists are trying to prove this theory from all directions. At present, this subversive theory is only left in the conjecture stage. Whether it is string theory or holographic universe theory, it is not easy to prove them through experiments.
We are more willing to accept string theory than the holographic theory of the universe that people can accept. Because string theory can at least prove that our universe is a real universe, not a three-dimensional projection of a two-dimensional world. It’s just that the truth of the facts is often unexpected, and we don’t know what the essence of the universe is.
