What are some physical facts that people without some knowledge of physics would not believe?

There is a physical fact that space and time are not continuous, and can be divided infinitely, space and time are independent, and the combination between them becomes space-time, and another point is that time can actually change, and speed can make time change, the faster the speed, the slower the time, the slower the speed, the faster the time.

Speed bumps, which are common in life, cars move slowly, do not feel bumps, and are very bumpy when passing quickly. This is a kind of knowledge of physics.

In quantum mechanics, space and time are not continuous and can be divided infinitely. After absorbing external heat, the temperature of a black hole decreases rather than rising. The theory of relativity holds that the universe is three-dimensional, and that the long sphere will go in one direction and eventually return to the starting point, similar to a circle around the earth.

For example, if you don't use a non-Newtonian fluid, the harder you hit this kind of object, the harder it becomes, and if you don't use force, it will become a soft lump. You can do a little home experiment, but pay attention to hygiene.

For non-Newtonian fluids, this phenomenon is very special, the greater the force, the harder it becomes, and conversely, it is soft and collapsed.

The earth is round, and the earth revolves around the sun.

Physics certainly exists.

Of course, physics exists, and now almost all mechanics, optics, electromagnetism, electrical engineering, microwaves, astronomy, and meteorology are separated from physics, and strictly speaking they still belong to physics. It's just a little more engineering. At present, the main directions of physics majors include theoretical physics, particle physics and nuclear physics, atomic and molecular physics, plasma physics, condensed matter physics, optics, acoustics, radio physics, astrophysics and other directions.

Theoretical physics is the physics of a large number of calculations, especially a large number of applications of mathematics, and also contains many aspects, all aspects, as long as a large number of theoretical mathematical calculations are involved, it is called theoretical physics. Condensed matter physics is a condensed state that considers solids, liquids, and tends to be between solids and liquids, and crystals are mostly in this state. Interestingly, almost all the disciplines are divided into physics, and although each discipline is full of flowers on the surface, they all have to meet certain mathematical laws, especially the conservation of matter, the conservation of momentum, the conservation of energy, the conservation of electromagnetism, these laws and their similar description methods penetrate into every branch of science.

Physics is the study of the most general laws of motion of matter and the basic structure of matter. As a leading discipline of natural science, physics studies the most basic forms and laws of motion of all matter, from the universe to elementary particles, so it has become the basis for the research of other natural science disciplines. Physics began in the days of Galileo and Newton, and it has become a fundamental science with many branches.

Physics is an experimental science, and it is also a science that advocates rationality and attaches importance to logical reasoning. Physics makes full use of mathematics as its working language, and it is one of the most sophisticated natural sciences today.

This is actually a flaw in the three-body problem - fundamentally, you can't actually prove that something is irregular.

Yang Dong will say that physics does not exist for reasons.

According to "The Three-Body Problem", the reason why Yang Dong said that physics does not exist and finally chose to commit suicide is related to the scientific and technological blockade of the three-body civilization on the earth civilization. After the Trisolaran civilization knew that there was a more backward civilization on Earth, they sent an interstellar fleet to fly to Earth. However, the technology of the three-body civilization is limited.

Their starfleet can only reach one-tenth of the speed of light after a long period of acceleration, and it takes about four hundred years to fly to Earth four light-years away. Considering that the development speed of the three-body civilization is linear, the development of human development civilization is explosive.

Although the technology of the Three-Body Civilization is ahead of the Earth Civilization, they are afraid that the Earth Civilization will have a technological ** and surpass the Three-Body Civilization within four hundred years, and then the colonies will be in vain. Therefore, the three-body civilization has tried to lock up the science and technology of mankind so that it cannot make breakthrough development.

**In addition to Yang Dong, a large number of scientists have chosen to commit suicide.

If Wang Miao hadn't learned some truths later, I guess I would have gone crazy if I didn't commit suicide. So I think Yang Dong is the same, when she knows that the laws of physics can be manipulated by "humans", (this does not actually mean that physics does not exist, it can only show that physics on the earth has been unable to develop due to the lock of protons).

To put it bluntly, any physics research done on the earth as a physics scientist will no longer have any meaning, and it will be meaningless to live on the earth, and the "culprit" who caused all this is his mother, so I think all this is fatal to Yang Dong. Yang Dong's suicide is different from the reason for the suicide of other scientists, because she knows the truth, but she can't tell the truth, so she can only leave "physics does not exist".

To change the unreality of physics, then you have to choose the non-suicidal path.

Indeed, the seemingly real theories of modern physics, when analyzed from the perspective of larger thinking reasoning, physical theories are really irrational theories, how to say that? For example, gravitational collapse, the theory of gravitation established by Newton is correct in the operation of the earth and solar system objects, but it cannot be explained in the case of galactic mergers or the rotation of electrons at the speed of light.

From the actual water whirlpool, Jupiter, hexagonal storm, typhoon, eye of the storm, etc., can not be explained by the theory of gravity, but these are observational facts, and have nothing to do with the theory of mass attraction, Einstein made a space-time bend, which made the physics community happy for nearly a hundred years.

As a result, the more headache-inducing singularity of the speed of light is online, and the bending of space-time pushes real physics to mathematics, approaches theology, and produces the "three-body problem", so that the human beings on the earth are trapped in their own evolutionary life path due to the physical wisdom created by human beings, and go to destruction.

We need to increase our knowledge base. There will always be science, scientists. Practice makes sense.

I think your question is a bit misleading. Physics, as a discipline, is the study of the laws of nature and the nature of the material world. Although physics is not omnipotent, it plays an irreplaceable role in our understanding of the natural world and is one of the cornerstones of modern science.

In life, we can also see many applications of physics, such as medical imaging, communication technology, energy development, etc. Therefore, studying physics helps us better understand the world, solve problems, and solve challenges. At the same time, by studying physics, we can also exercise logical thinking and scientific literacy, and cultivate the ability to innovate and solve practical problems.

This question is to be under the three-body worldview. In the real world, perhaps the question is, 'If physics doesn't exist, then why do we study physics?' ’

In fact, in the three-body world, experimental physicists can still threaten the three-body people with their knowledge: Wang Miao, a nanomaterials scientist, he developed nanomaterials, not only used to make accelerator-related parts, but also made flying blades, helped the military dismember the second Red Bank Inquisitor, and later, the earthlings used nanomaterials to build a space elevator, built a space fleet and a space city, and made great strides into the space age.

In reality, physics is the foundation of many other disciplines, such as engineering, medicine, and technology. It can help people understand how the world works and how to use that knowledge to solve problems. For example, physics can help engineers develop more effective techniques, help doctors better ** disease, and help scientists research how to use energy.

The purpose of physics is to predict the state of objects in nature at the next moment.

The so-called physics, in fact, human beings summarize and summarize the laws of motion of natural objects (but this summary is not absolutely correct, but the probability of being correct is larger, when another theory with a greater probability of correctness is summarized, this new summary will replace the old summary and form a new physical theory, so physics is a long-term improvement process, which is why human beings have been studying the purpose of nature), and then use the summarized physical theory to predict the phenomena in nature. Determine what the next state of a certain physics in nature will be.
