The universe is divided into layers, what each layer is, and what it does

The atmosphere is divided into five layers, the troposphere, stratosphere, mesosphere, warm layer, and fugitive layer.

The troposphere is called the troposphere in the range from the surface to 8 to 15 km in height. The thickness of the troposphere varies from region to region and season, from about 15 km near the equator to 8 12 km at high and mid-latitudes. The troposphere concentrates the mass of the entire atmosphere3 4.

The temperature of the troposphere decreases with the increase of altitude, and the temperature decreases for every 100 meters of altitude, and the temperature at the tropopause is about -83 at low latitudes and -53 at high latitudes. Due to the vertical convection between the temperature of the near-surface air and the cold air at high altitude after receiving the thermal radiation from the ground, the strong convective movement of the tropospheric air is constituted, and weather phenomena such as clouds and precipitation occur in this layer. The troposphere is the level that has the greatest impact on human production and life, and air pollution mainly occurs in this layer, especially within 1 2 kilometers near the ground.

The stratosphere is called the stratosphere in the range from the tropopause to an altitude of 55 km. The ozone layer, which is vital for life on Earth, is included in the stratosphere, and the amount of ozone increases from the tropopause to a maximum of 22.25 kilometres, then decreases to a negligible amount at the stratopause.

The temperature of the stratosphere first does not change with the increase of altitude, or changes very little, to the altitude of 30 to 35 km, and then the temperature increases with the altitude, and the temperature rises to more than -3 at the top of the stratosphere. The increase in stratospheric temperature is mainly due to the ozone of the ozone layer absorbing ultraviolet rays from the sun while releasing a large amount of energy in the form of heat. Because the vertical convective movement in the stratosphere is very small, mostly advection, there are no weather phenomena such as clouds and rain in the troposphere, there is very little dust, and the atmosphere is transparent, so it is an ideal place for modern supersonic aircraft to fly.

The middle layer is called the middle layer from the top of the stratosphere to 85 km, also known as the middle layer. Because there is no ozone in the middle layer that can directly absorb solar radiation energy, the temperature decreases rapidly with the increase of altitude, and the temperature at the top of the middle layer can be lower than -83.

Warm Layer The range from the mesopause to 800 km is called the warm layer, also known as the ionosphere. This layer of air is very dense and the gas is ionized by cosmic rays. Since the ionized oxygen energy strongly absorbs the short-wave radiation of the sun, the air heats up rapidly, and the air temperature distribution increases with altitude, reaching 480 to 1230 at its top.

The ionosphere reflects electromagnetic waves back to Earth and is of great significance to global radio communications.

Fugitive Layer The atmosphere above the warm top is collectively known as the fugitive layer, also known as the outer layer. The atmosphere in this layer is extremely thin, the temperature is high, the molecular movement speed is fast, and some high-speed moving particles can overcome the gravitational pull of the earth and escape into space, so it is called the fugitive layer.

If you ask how many layers each universe has, it is considered that it is divided and easy to understand, but they are not much different from the macroscopic level.

All ideas are described by human beings!

What is inferred! Guess! Humans speculate that the universe is a sphere!

Divided into 2 worlds! Upper and lower levels! UFOs may have come from the world above!

But! This is the theory of man! I can't explain!

Is this theory true?

The three levels of the universe are:

Star systems (e.g. solar system).

Local galaxies (e.g. silver systems).

Zodiac signs (e.g. Virgo).

What are the three levels of structure of the universe? The relationship between them must be very complicated.

1. At present, we are entering an uncharted territory. For thousands of years, humans have been discussing life, especially intelligent life in the universe. While there has been no evidence yet, it is likely that this era is nearing its end.

2. The "exoplanet" revolution of the past 20 years has shown us that the universe is full of extraterrestrial worlds. What's even more exciting is that we now have the means that the atmospheres of these worlds can provide circumstantial evidence – "biosignatures" that can indicate the existence of extraterrestrial life.

3. One possible answer to Fermi's paradox is that civilization doesn't last long. Professor Leob stated that even after the end of civilization, some technical features remained. When we study planets, we may find some remnants of civilizations that no longer exist.

4. The stellar energy panels that cover the planet's surface are one such possible example, and they can exist on the planet's surface for a long time after the civilization that built them is gone.

5. In addition, there are some technical characteristics that may not be something we can find now. Once a civilization evolves into an interplanetary civilization, there will be many flying machines in space, not on planets. However, due to their small size, it is difficult to observe these technical characteristics directly at present.

When human beings left the earth, scientists have always hoped to find extraterrestrial life or even extraterrestrial civilization, but what disappoints people is that until now, more than half a century has passed, and we have not found any traces of extraterrestrial life and extraterrestrial civilization.

Isn't there any other extraterrestrial civilization in the universe? Are humans the only intelligent civilization in the universe? If someone raises such a question, many people may say that this is the cognition of the frog at the bottom of the well, how can there be only one civilization in such a vast and boundless universe?

If there are other civilizations in the universe, why haven't we discovered anything? Could it be that they are also like humans, and their scientific and technological strength is still very backward and they cannot carry out interstellar exploration?

I believe that many people know the famous "Fermi paradox", Fermi believes that human beings have not encountered other civilizations, which is itself a "paradox", and we have no way to explain it well, why did extraterrestrial civilizations not appear? You must know that from the perspective of the universe, if alien civilizations exist, then their scientific and technological strength may far exceed that of human beings.

Human beings at the cosmic level are only an accidental by-product of the evolution of the universe, just the result of the superposition of many accidental factors.

Oh, it's even more bitter, Li Ruijie gave the fat cow to drink the red bull and hummed the proposal, oh, obviously self-help note-taking me.

1. The universe is composed of light matter and dark matter, of which the light matter is the matter that we can see, such as stars and nebulae, which only accounts for a few percent of the universe. The other part is made up of invisible dark matter, which makes up more than 90 percent of the universe.

2. The universe is composed of the "color" of material phenomena and the heart of life phenomena

1. Color refers to material phenomena:

All cosmic material color phenomena are caused by earth, water, wind, and fire. The four species are combined with each other.

2. The mind refers to the phenomenon of life in the universe

Heart: It is all phenomena related to the spiritual and ideological activities of life.

3. There is anything in the universe that can be simply divided into two parts: yin and yang

As long as all the theories and imaginary things of man exist in your brain, the universe exists, man is a part of the universe, human consciousness is equivalent to a part of the consciousness of the universe, the brain produces all kinds of consciousness are governed by the laws of the universe, man can represent the whole of the universe, the universe can give birth to matter that can move freely and make it able to produce consciousness to question itself, it can be seen that the universe has exceeded the imagination of human beings.
