What is the problem at the forefront of space physics now?

Space is energy, energy is matter, and matter is time. There is nothing that there is no space, the universe is infinite, the universe is infinite, the universe is everything, the speed of light is not the upper limit of the speed of the universe, it's just that human beings have not yet recognized that energy level, but it does exist, it is all around us! Also, the universe is not made up of a singularity, but by infinite levels of energy distortions (hypothetical curves) that interact to form a force of rules that everything in the universe operates according to the power of this rule!

Different levels of energy (or in the form of "matter" before our eyes) will manifest themselves in different ways. Of course, the energy level can be crossed! We can condense the energy that we can use directly or indirectly (such as light energy), if we condense the light energy without limit, condense and condense and then condense, then the energy level will eventually move to a certain extent, and when the light energy is condensed to a certain extent, it will detonate the deep energy form and move over (there will always be a greater energy more and more migration to the energy level that we can directly or indirectly use), this is the energy machine that can obtain energy from the so-called "vacuum"!

String theory, black holes, the possibility of time travel.

Two dark and one dark. Dark matter, dark energy, black holes.

Particle Physics: Aspects of the Origin of Matter, Fundamental Role Unification.

Special Relativity: Multi-particle systems.

General Relativity and Cosmology: The theory of the universe and the fact that the theory supports the nonlinear aspect.

Materials: Mesoscopic scale material theory research. Including some research on condensed matter, superconductivity, semiconductors, etc.

Theoretically, anywhere, it's random. As for how it appears, some scientists speculate that wormholes are created when enough energy gathers in a small space. Some scientists predict that wormholes cannot be artificially created.

As for how long, I haven't seen any articles about it. Everything is in theory, no one has ever seen a wormhole, and everyone who has seen it can't speak! Although many people say that traveling through time is fantasy, I believe that one day we will succeed!

I'm working on it too. Let's see who "digs" the wormhole first!!

At present, scientific research is only in the conjecture stage, and no one has seen it.

If you are interested, I recommend watching Stephen Hawking's "A Brief History of Time" and "The Universe in the Shell".

You go and find out "what's in the rabbit hole".

Or take a look at "Quantum" written by Takayama

It's very popular and easy to understand.

When it can no longer be plugged, that is to say, the hollow hose will eventually become a very strong and small round cake;

Eventually, it will turn into a round plate.

Space physics is an emerging discipline that has developed rapidly since mankind entered the space age. It mainly studies the physical phenomena and laws in the solar system, especially the solar-terrestrial space, and studies the space environment and its impact on human space activities and the ecological environment.

At present, Peking University, Wuhan University, University of Science and Technology of China, Graduate School of Chinese Academy of Sciences and other enrollment units recruit master's and doctoral students in space physics.

Who is suitable for Space Physics? What should candidates pay attention to when preparing for the exam? The reporter interviewed relevant experts from the Space Science and Application Research Center of the Chinese Academy of Sciences on these issues.

The first professional course only tests the basic knowledge.

Most colleges and universities in China do not set up space physics majors at the undergraduate level, so many candidates do not know about this major, and think that the preliminary examination of this major will involve the content of space physics, which is difficult to review, so they dare not apply for the examination. In fact, many admissions units do not test the professional knowledge of space physics, but only test the basic knowledge such as general physics, which is generally studied by candidates majoring in physics in the undergraduate program. For example, the preliminary examination of space physics at the Graduate School of the Chinese Academy of Sciences only examines general physics or electrodynamics.

Although the University of Science and Technology of China (USTC) examines the basics of space physics in the preliminary examination, the content of the exam is the knowledge of space physics in general physics, and the reference textbook is the general physics textbook of the physics department of USTC, Peking University or other universities.

Select the research direction based on the disciplinary background.

It can be seen from the setting of the professional course of the preliminary examination that candidates with a background in physics are suitable for applying for the space physics major. Space physics is an interdisciplinary discipline, and in addition to candidates majoring in physics, candidates with backgrounds in mathematics, astronomy, and meteorology can also apply for space physics majors. In the process of postgraduate training, it is also found that some graduate students have studied computational mathematics before, so they have obvious advantages when doing research work related to numerical simulation.

Candidates with different professional backgrounds can choose the research direction under the space physics major according to their own strengths. The research directions of this major include space meteorology, Martian magnetosphere and ionosphere research, ionospheric physics, middle and upper atmosphere physics, magnetospheric physics, plasma physics, space environment science, space exploration technology, etc.

Most of the graduates choose to further their studies.

After graduating from the master's degree in space physics, a large number of students choose to continue their studies and engage in scientific research. For example, half of the 2006 graduates of the School of Earth and Space Sciences of Peking University chose to continue their studies, and some graduates were employed in scientific research units such as the China Academy of Aerospace Science and Industry Information Technology. Graduates of the Space Science and Application Research Center of the Chinese Academy of Sciences have also entered universities and scientific research institutes.

Space technology.

Quantum physics. Countries around the world are actively developing space technology, and if you pay attention to technology news, you will find that there is a lot of news about space. News such as mobile phones is commercial in nature. Space technology is likely to play a huge role in the future.

Humanity has always cared about the biggest thing in the world and the smallest thing in the world. The largest is space, and the smallest is quantum physics.

Pure development is not very good, and generally practical development is done.

Generally speaking, the development of theoretical physics in the future will be diversified and refined, and it is almost impossible to appear such "unified" masters as Newton and Maxwell.

Casually suspect the landlord, you may not understand what "theoretical physics" means...

Microelectronics, Materials.

At present, electronic products are developing rapidly, and the most basic is materials.

It's really hard to think, you can only touch the manuscript to separately examine the balance of the two stoves in one direction, and the friction force after the tilt in each direction is equal to the downward division force, and then find the friction force. Since it is square, the friction force in the final two directions is equal and perpendicular to each other, so the combined friction is twice the root number in each direction.
