What is the study of time, space, space, and space

There are three disciplines that deal with these aspects.

The first is physics, to be precise, astrophysics. It discusses the mutual laws of the celestial bodies, as well as the creation, transformation and development of the universe.

The second is obvious astronomy. Astronomy mainly deals with phenomena, that is, mainly phenomena that can be seen with the naked eye (or with the help of tools), such as the appearance of red giants, the discovery of star clusters, the discovery of asteroids, the position and changes of constellations, etc.

The third is philosophy, which is not thought of by ordinary people, and which also considers the question of the universe, and which was the main subject of discussing the universe of time before Copernicus.

Of course, knowledge is interconnected, and all three of them have some intersection.

If you study it together, it's physics, and the smaller point is cosmology. In fact, there are also spatial and temporal studies, time credits, theoretical chronology, and applied chronology. If you want to learn, study cosmology.

At this stage, the actual significance of space exploration is not what problems can be solved. The essence of cosmic exploration is a manifestation of man's endless curiosity, and at the same time a way for the state to assert its strength. Various resources can be explored, such as life forms and dark matter.

Unknown elements, etc., in short, are things that the earth does not have, which can improve human technological civilization and make human beings live better. The significance of cosmic research is to satisfy the curiosity of human beings, realize the ideals of the present stage, explore the mysteries of deep space, and benefit mankind in the process.

The scientific significance of extraterrestrial exploration is many, and his influence will be in all aspects in the future, as we all know, human beings have a recorded history of thousands of years, but since China's reform and opening up.

40 years ago, China did not even have black and white television, and even bicycles were not available in many families, and they could only be said to be full, pork was still a luxury, and communication still relied on letter writing and transportation.

Needless to say, a little farther inter-provincial transportation, it takes a few days, or even more than ten days, to do a train, but after the development of the past 40 years, we take a look, our food, clothing, housing and transportation compared with the past, it is simply the difference between heaven and earth.

It is necessary that human beings are too small for the universe, and understanding the universe, studying the universe, and developing the universe are the continuation of the earth and life. Safety, prevention and control of damage to the earth and life such as cosmic stones, accelerate the study of the origin of cosmic energy, and finally find out the life and death of the universe, the study of energy is an important technology for the protection of the earth and the continuation of life, and it is an important technology for human beings to rush out of the solar system and understand the Milky Way.

The beginnings of modern physics began with the study of astronomy, with the invention of the telescope, Galileo.

Kepler and so on were summarized through observation and analysis, and then Newton.

The study of reasoning opened up classical mechanics....There are also electricity, magnetism, light, etc., which are all widely present in the universe.

The significance of human exploration of the universe is to reveal the formation and evolution of the universe, explore the origin of life and the influence of the space environment on the living environment of human beings, and play a huge role in promoting the development of astronomy, cosmology, material science, life science and ideological science.

The significance of space research is for the better survival and development of our human beings, so that when the earth is destroyed, we can find a better planet.

The significance of studying the universe is to enable people to explore the universe, the composition of the universe, the development of the universe, what changes the universe can have in the future, and what kind of life the universe will bring us.

1. Practical observation: telescope observation, spacecraft, artificial satellite, spectral analysis, cosmic firing line analysis, etc.

2. Theoretical derivation: For example, the theory of stellar evolution, the theory of double stars, and the theory of the universe are established, and the famous mysterious celestial body "black hole" is deduced through theory. Scientists use physics, mathematics and other aspects of knowledge to establish theories on the basis of cosmic observations, and serve the observations, such as Uranus, Neptune, Pluto, etc., are discovered through theories to discover their possible existence and their orbits.

3. Experiment: The famous Particle Collider is an experimental facility built for the study of cosmology and high-energy physics, and it is said that the large-scale particle collider can simulate the scene of the universe just one ten-thousandth of a second ago.

There are too many traces of this party's letter.

1. Macroscopically, including the discovery of extragalaxies and the measurement of the cosmic extent.

2. Microscopically, study the operation of specific galaxies, Centauri, Andromeda, solar system and other celestial bodies.

3. Theoretically, the most important thing in studying the theory of the development of the universe is the theory of the great universe.

4. In terms of exploration, look for extraterrestrial creatures and find a planet that can be used as human survival.

5. In terms of research, including academic research on black holes, four-dimensional space, space-time tunnels, etc.

6. In terms of protection, study the law and development of celestial motion, including the monitoring of asteroid belts. Keeping the planet safe.

7. Academically, the study of matter and antimatter. For the presence of faster-than-light and other studies.

8. Technically, launch the Explorer, Discoverer and other brigades and study the Martian landform, whether there is water, etc.

9. Religiously, study whether the universe was created by God, and so on.

There is a principle of the theory of relativity called the slowing down of the moving clock, that is, the speed of time flow in the moving body is slower than that of the stationary object, that is, the slow movement of the clock, the physiological activity of the person will be slowed down, and even the rotation of electrons in the atom around the nucleus will be slowed down accordingly. The faster it is, the more it slows down. However, this phenomenon is not obvious at low speeds, so that we can't find it in our daily life, but it can be reflected when moving at high speeds.

And time on Earth is a fixed time for human beings, and the Earth is in three-dimensional space, and the universe has at least 9 dimensions or more, different dimensions, different time patterns, and for the creation of the universe, that is, for the universe as a whole, there is no such thing as time, because everything just exists, and the plane universe, you know, is the present you, the past you, and the future you, all in this space, three in one.

The concept of cosmic time you are talking about should be time at different speeds.
