There is a vacuum in the universe, so there is no gas, and the gas will exist in the form of molecules in the universe, and it will be very thin.
The universe is a stable and balanced energy system, there should be "positive" matter and "anti" matter, the positive and anti matter energy is equal, and the total energy is 0According to the principle of lowest energy, there is gravity between the "positive" matter, and there is also a gravitational force between the "anti" matter, and the positive and antimatter should be repulsive between them, but annihilation occurs when they are close. So the universe should be in the shape of a figure 8.
Half is the "positive" universe and the other half is the "anti" universe. Suppose our universe is a "positive" universe and the other universe is an "anti" universe. The center of the universe in the shape of an "8" is called the "singularity".
There are two vibrations and two rotations in the figure-8" universe. The so-called ordinary matter is the cosmic energy that can be detected by human beings using electromagnetic waves, and dark matter is the cosmic energy that cannot be detected by human electromagnetic waves. The most abundant amount of dark energy is similar to "cosmic background radiation".
From the composition ratio, it can be seen that the visible matter is the least, the dark matter is the second, and the dark energy is the most.

Matter is not extinguished, and gas will be matter in space!
Jupiter is a gas planet, and the main elements of the Sun are also the elements that make up the gases.
In addition, some gases will freeze into solids in the cold environment of space. For example, there is something white on the polar crown of Mars, not ice, but dry ice, frozen carbon dioxide.
Stars such as the Sun are born in nebulae, which are mainly large clouds of gas. In fact, the largest proportion of cosmic matter is gaseous matter.
By gas, we mean those things that have the word gas next to them on the periodic table. If a piece of iron is close to the sun, it will also be turned into gas, and the three states will be transformed.

There is no gas in the cosmic space between celestial bodies, and dark matter exists. Gas can only be found on planets and moons with large masses, in the form of atmospheres, etc. There is no gas on the surface of the star, it is plasma.
Again: How is the gas formed? Does gas exist in the universe?
Answer: First of all, the main forms of matter in the universe are: plasma state (the most common form), neutron state, supersolid state, black hole state, solid state, liquid state, gaseous state, etc.
The latter three will only be found on planets and moons with relatively low temperature and pressure, but with sufficient mass and gravity. The formation of gases is due to the fact that in addition to a large amount of dark matter, the visible matter is mainly composed of the simplest elementary particles such as protons, neutrons and electrons (nuclear physics content, high school physics is briefly mentioned, specifically to be studied in college), and usually, the matter in the universe is formed by the atoms of the simplest two elements: hydrogen and helium.
Hydrogen accounts for the vast majority of this. Heavier gas atoms such as nitrogen, oxygen, and fluorine are products of the supernova baozha. These atoms can only be combined into molecules on planets and moons at relatively low temperatures and low pressures, and exist in a gaseous state.
If the gas is subjected to a higher temperature, it will become plasma-state, and the atoms will not be able to bind electrons, forming a plasma state. When subjected to higher temperatures and pressures, it will gradually become a dense state such as ultra-solid, neutron state, and black hole state. Of course, gas exists in the universe, but the gaseous state is a very rare state relative to the universe.
And the statement that stars are made of gas is what the old version of the book says, which is wrong, and should be in a plasma state. The planets are filled with dark matter (not a vacuum) and extremely thin cosmic rays and particles.

The universe is magical, there are many unknown mysteries that we need to explore, and we are also full of endless curiosity about the universe, so do you know why the atmosphere does not emit from the universe? Then the next step is byKnowledge of horoscopesLet's reveal it for everyone!
Why the atmosphere doesn't emanate in the universe.
The total mass of gases in the Earth's atmosphere is about grams, which is equivalent to parts per million of the total mass of the Earth; The Earth's atmosphere is extremely important to life on Earth, and it can be said that there would be no life on Earth without an atmosphere.
There are two main reasons why the Earth's atmosphere does not dissipate in space:
First, the restraint of Earth's gravity.
Due to gravity, almost all of the gas is concentrated in the range of 100 km above the ground, and 75% of the atmosphere is concentrated in the troposphere at an altitude of 10 km above the ground.
The second is due to the protection of the Earth's magnetic field.
The solar wind is a stream of ultra-high-velocity plasma (charged particles) ejected from the upper atmosphere of a star; The wind speed of the solar wind is often maintained at 350 450 kilometers per second near the earth, which is tens of thousands of times the speed of the earth's wind, and can reach more than 800 kilometers per second at its most violent;
Without the Earth's magnetic field forming an ionosphere (a protective layer of charged gases) in the outermost layer of the Earth's atmosphere, the Earth's atmosphere, like the Martian atmosphere, would be slowly stripped away by the solar wind and eventually disappear.

There are gases like hydrogen, helium, oxygen, nitrogen, carbon dioxide, etc. in the universe.
1. Hydrogen. It is a colorless, tasteless, odorless, and extremely flammable gas composed of diatomic molecules, and hydrogen is the lightest gas.
2. Helium. It is a type of noble gas. The name of the element is derived from the Greek word for "sun".
3. Oxygen. Colorless and odorless gas, the most common elemental form of oxygen.
4. Nitrogen. It is usually a colorless and odorless gas, and nitrogen is generally less dense than air.
5. Carbon dioxide. It is a common compound in the air, carbon reacts with oxygen to form its chemical formula CO2, a carbon dioxide molecule is composed of two oxygen atoms and one carbon atom through covalent bonds.

Broadly speaking, gases, note is"Gas"Ah, yes, because no matter what, the atmospheres of other planets will also spread into the universe. As for the sun, this is the nuclear fusion that takes place in the plasma, and it cannot be considered a gas, although its density is also very small.
-
There is no gas in space, you can do an experiment, you say a word, let others listen, if you hear it, there will be air, if you don't hear it, there will be no air, because there are three ways for sound to travel: solid, liquid, and air.
-
Space is in a vacuum, there is no air.
Air is only available within the Earth's atmosphere. Other planets with atmospheres also have air, but not the same composition as Earth. Only planets with an atmosphere, rich in oxygen, surface water, and a small temperature difference between day and night are possible for life.
-
There is no air in the universe, and although it is in a vacuum, it is not nothing, and there are about three elementary particles in each cube. For example, various rays, neutrinos, and so on.
-
The density of molecules in the universe is very low, only a few cubic centimeters. So there's no air. Nor does there be a wind in the form of the Earth. But there will be a stream of high-energy particles emitted by the sun or stars. The former is called the solar wind, and the latter is called the star wind.
-
No, because the ship is made of special materials. Although there is no air in space, the spacecraft mainly relies on inertia, but when the spacecraft needs to accelerate, it can rely on planetary gravity as a power, but when it needs to change direction, it has liquid hydrogen and oxygen or other accelerants, and it burns by hydrogen to produce instantaneous water vapor and air masses at the tail of the spacecraft, so that the spacecraft can generate forward propulsion through the instantaneous air mass at the tail.
-
Yes, but very little, such as a comet flying by and leaving behind water vapor. Some planets with little gravity can't retain their atmosphere, and the atmosphere slips into the universe, and Mars is a good example.
-
Human beings have very limited knowledge of the universe.
In the vast environment of the universe, there is no air, because air also has mass, and can only be attached to the surface of the planet by the gravitational pull of the planet. The reason why the spaceship will not ** is because of the special compression-resistant materials and manufacturing processes used in the construction.
However, there is no vacuum in the cosmic environment, so there should be a borrowing point when braking. Once the borrowing point exists, then all the problems should be solved.

The universe is not a vacuum, there are countless galaxies in the universe, and some people have suggested that the galaxies of the universe are just images and not real. I don't know if the matter in other parts of the universe is real, but my relatives and friends, and my home, are real, not vacuum.
And there is no absolute vacuum. The universe is not a vacuum, there is still small gas in the universe, although the meager pressure is small, compared with the air on the earth, the universe is only close to a vacuum. Hawking also said that the origin of the universe is like bubbles in boiling water, and too many bubbles appear and disappear, implying the expansion and disappearance of the universe.
Maybe our universe is a bubble.
Looking at the two bubbles in the center of the Milky Way, tens of thousands of light-years to both sides, then this structure called "Fermi bubble" by scientists is not a vacuum. There's still a lot of stuff in the bubble. The universe is a vacuum, and it is precisely because of the vacuum that the dust between the universe floats in space, and these dust comes from the beginning of the universe.
When we talk about the vacuum of the universe, we have misunderstood the definition of matter based on the so-called physical cognition. The universe is not empty at all, so the so-called material entities of all things in the universe are ignored, and the "emptiness" of the universe is also the "real" essence of the formless soul that is not empty in nature. It's just that human beings are invisible, and in terms of the form of existence, the "vacuum" shows the essence of the universe and all things.
Dust and fog fill the space, ** different points, forming a universe in different directions. There is no boundary between the universe and the intersection of the universe, but the space will be different, and it should be an area of energy overlap. Dust and fog fill the space, ** different points, forming a universe in different directions.
There is no boundary between the universe and the intersection of the universe, but the space will be different, and it should be an area of energy overlap.
The definition of the universe is: The universe is an inseparable trinity of mass, energy and space, so there is never a vacuum in the universe. Therefore, the third postulate of Einstein's theory of relativity: the velocity of light in a vacuum is constant and unverifiable.
-
It's true, there is a lot of gas and dust in the universe, but there is no oxygen in the universe, and there is no gravity.
-
It's true, the universe is very big, and there is a lot of dust and gas in the universe, but we don't usually see it.
-
Yes. The universe is very big, endless, with a lot of dust and gas.

The universe is made up of energy, space, and matter. Some matter wanders through space in the form of atoms or simple gas molecules. Others are clustered in islands of matter as small as dust particles to as large as star systems, and even collapse into black holes.
Gravity binds all these objects to galaxies made up of giant clouds and disks of matter. The galaxies in turn converge into galaxy clusters, which in turn form the supercluster, the largest celestial body in the universe.
Many ordinary matter in the universe exists in the form of thin gases in or near galaxies. The gas between galaxies is even thinner. This type of gas is mainly composed of hydrogen atoms and helium atoms.
Clouds in galaxies contain heavier chemical elements and simple molecules. Mixed with the galactic gas cloud is also dust. They are tiny solid particles formed by carbon and other substances such as silicates (silicons).
In galaxies, gas and dust together make up the interstellar medium. The visible mass of medium is called a nebula, and many of them are where stars form. There is a class of media called emission nebulae that emit photons again after their atoms absorb radiation from the star, creating a bright glow.
In contrast, dark nebulae can only be spotted when they block the starlight to form dark spots. Particles of matter also exist in cosmic space in the form of cosmic rays. Cosmic rays are high-energy subatomic particles that move at high speeds in the universe.
Barnard 68 is a typical dark nebula. It is a pellet made up of dust and dense gases. Thick dust obscured the dense star field behind.
The ship's bottom nebula is a giant gas cloud visible to the naked eye. It is very noticeable in the night sky of the Southern Hemisphere. The different colors on this image represent gases of different temperatures.
The red-hot gas in the Omega Nebula is an active star-forming region. Clouds of gas and dust can give birth to stars and planets, but they can also be blown away by dead stars and then enter the cycle of the next generation of stars.

Stars in the universe are made up of hydrogen and helium, and when a large amount of hydrogen and helium are gathered together, the huge mass creates a huge gravitational pull, causing the hydrogen inside to fuse under high temperature and high pressure to form stars.
<> the stars in the universe are explored from nebulae, and nebulae themselves are interstellar dust and other gases, although the individual mass of these interstellar dust and gases is very small, but the diameter of the nebula has reached the level of light in the universe, and the total mass of such a large-scale nebula is also very breathtaking, but the density of nebulae is very small, and you have to be far enough away to see the whole picture of the nebula.
The density in the nebula is not the same, and in some parts of the nebula, hydrogen will slowly heat up, because the density is too large, the heating of hydrogen will drive the surrounding matter to heat up together, and then according to the law of gravitation, dust and gas gather together to form stars, and the temperature of the matter in the center of the astrolabe rises sharply, and then it becomes a protostar under the action of gravity.
The protostar will continue to attract other matter to increase its mass over time, and the internal temperature of the protostar will reach tens of millions of degrees after the mass reaches a certain level, and when the mass reaches tens of millions of degrees of high temperature and pressure, hydrogen fusion reactions will occur inside the protostar, and slowly the protostar will slowly ignite from the inside, and finally spread to the entire star. The formation of celestial bodies, such as galaxies, is caused by the ubiquitous gravitational pull. Although the density of interstellar gases in the universe is low, under the influence of gravity, they are constantly gathering and contracting, and when they grow to a certain extent, they can form stars and planets.
This is how our solar system was born.
Interstellar gas begins to form thin interstellar clouds. Under gravity, they condense and contract very slowly, accelerating when large amounts of gas and dust gather together. If the interstellar cloud is spinning at the beginning, then as it shrinks in size, the rotation will begin to accelerate.
Eventually, the core of the entire interstellar cloud becomes dense.
Because there is gravitational attraction between the planets. Gravitational forces provide the centripetal force that allows the planets to move in a circle around a central body (the orbit is elliptical) so that the two planets do not fit together. >>>More
How do you define your strongest?
Aside from the universe, as far as the earth is concerned, the tiger is the king of all beasts, and humans will definitely not be able to fight alone. If we compare IQ and technology, then the current universe is still unknown to most of human beings, and we cannot make a summary conclusion about the unknown, but can only get a phased conclusion, so as of the beginning of 2009, the human beings located on Earth, the third planet of the solar system of the Milky Way, are currently the strongest race in the universe known to this race in the category of "science" excluding religion and so on. Are you satisfied with that? >>>More
The universe is a realm full of wonders and unknowns for us, but it is simply impossible to explore them deeply with the current technology of human beings. Although the civilization of our earth has made great breakthroughs in the past few decades, it is far from being able to explore the distant and vast universe, even the solar system we have not yet been able to go out, let alone other fields. >>>More
Would you believe it? Humanity is the first civilization in the universe! This is not credible for us, because we really have no way to prove it now, because the other civilizations on our team have explored for so long and still found nothing, which has to make us doubt whether the other civilizations on our team exist. >>>More
