If the Earth is weightless, does the Earth still have an atmosphere??? Will there still be oxygen?

The weightlessness of the earth will make what was originally balanced become unbalanced. The air used to be constrained by gravity, but now that gravity is gone, the gravitational pull between the air may take over, and there will be a rebalance, that is, the air is likely to become liquid or solid. Because there is no external force, the air will not be lost to space, so if the air does not become liquid or solid, there will still be air and oxygen.

But the earth is weightless, not only the air balance will be broken, but the balance of the earth itself will also be broken, and the huge energy inside the earth is likely to produce a new balance through **. This new equilibrium, this ** will make the earth a new space junk, that is, the earth is weightless, and the earth will cease to exist.

Of course not, first of all, everything on the earth moves in a circular motion with the rotation of the earth, and when the gravitational force disappears, these substances will fly to the universe in an instant, and there will be a twelve-level wind.

This question is not quite accurate, weightlessness is not the same as losing gravity. When we talk about weightlessness, we mean that an object is not subject to the gravitational pull of other objects, such as a spaceship floating in deep space (of course, it is not absolutely gravitational, but the gravitational attraction of other celestial bodies to it is very small); The second refers to the gravitational force experienced by the object as a centripetal force that makes the object move in a circle or ellipse, such as an astronaut walking in space; In addition, the state of an object when it falls freely can also be called weightlessness. Therefore, the earth is already in a weightless state of orbiting the sun in the solar system.

Your question should be if the Earth loses its gravitational pull. If the earth loses its gravitational pull, not only the atmosphere, but also oxygen, but everything else on the earth's surface, water, and earth will be lost into space, but of course this can only be a hypothesis.

If there is no gravity, the atmosphere will gradually escape, and there will be no atmosphere. Oxygen will still exist, but it's all in outer space.

The atmosphere is the umbrella of life on earth, it protects the survival and reproduction of life on earth, without the atmosphere, human beings, animals and plants will be damaged by ultraviolet rays, and the rupture of the earth's atmosphere will bring extinction to all living creatures on earth.

Like water on Earth, the Earth's atmosphere is actually very thin and insignificant compared to the Earth's mass. It takes a long time for it to become what it is now, and it is impossible to maintain it in its constant state for a long time. Every moment on Earth, a large amount of gas escapes into the universe.

Some of the components that make up the atmosphere cannot be recovered, and one can only watch them depleted. The conditions for maintaining the existence of the atmosphere are complex, and there is a balance between loss and regeneration, and there are many unknown factors that people need to understand, but this balance can be broken at any time.

Because the Earth's surface is not protected by the atmosphere, the surface temperature rises rapidly. Oceans, lakes, rivers evaporate. It didn't take long for the Earth to fill the earth with an atmosphere made up of water vapor.

External water molecules are broken down into hydrogen and oxygen by cosmic rays. But all plants on Earth that have chlorophyll are scorched and unable to form carbon dioxide. The Earth's surface is hot, and the newly created atmosphere is filled with water vapor, hydrogen, and oxygen, and there is no liquid water on the surface.

All the people outside died. In a closed room, if there are too many windows and the sun is exposed, it is also certain to die. Without the protection of the atmosphere, many rays will directly hit the human body, which will directly scorch.

There are also not many spacesuits that maintain air pressure. Therefore, only people in the environment of biological laboratories or spacesuits can survive. And when the air in the spacesuit is consumed, all human beings around the world die.

Changes in the earth's environment, especially in the water environment and atmospheric environment, make the earth no longer suitable for human life much faster than the aging rate of the sun.

For human beings, it is more urgent and important to care about the earth's environmental changes than about the aging of the sun.

Then this earth will definitely become lifeless, and all kinds of disasters will break out at any time, such as possible out**, tsunamis, typhoons, fires, etc., and the plants on the earth will also die, especially animals and humans will face the danger of extinction, maybe when the atmosphere ruptures, the earth will be really destroyed.

If the atmosphere is broken, the earth will be flooded with ultraviolet rays, and people will not be able to resist this ultraviolet rays. Life on Earth is no longer protected, and the air becomes very thin and cannot provide enough breathing for humans. It will also lead to serious damage to the ecological balance.

The earth may disappear, and all the animals, plants, and humans may perish, because once there is no oxygen in the atmosphere, then all the animals and plants will suffocate, which will lead to death.

There is a high probability that the Earth will be destroyed, or it will be a ruin, because after the destruction of the atmosphere, there will be no signs of life on the Earth, and all life will be extinct at this time.

If the atmosphere is broken, the earth will become a sea of fire, all the water on the earth will evaporate, and all the plants and animals will die.

Personally, I feel that this earth will definitely become very chaotic, and the earth will gradually be destroyed, because the atmosphere is also very important in the earth.

Even if people leave the atmosphere, they will not be without gravity, and they are still pulled by gravity, but this force is one percent of the earth's surface.

Everything that surrounds the Earth is affected by the Earth's gravity, and this invisible force is so strong that it can even attract gases, so the Earth will have an atmosphere.

The International Space Station and artificial satellites, which appear to be floating in the universe, are in fact constantly falling, and must accelerate from time to time in order to prevent them from stalling and falling into the atmosphere. The speed is generally maintained at 500 meters per second, which is slightly faster than the Earth's rotation. (The Earth's rotation speed is 466 meters per second).

At about 9:30 a.m. local time on October 14, 2012, that is, at about 11:30 p.m. Beijing time on the 14th, Baumgartner lifted off in the Rosville area of New Mexico, USA. Due to the low air resistance in the stratosphere, he fell in free fall until he exceeded the speed of sound before opening the parachute.

He didn't choose to fly either, but flew to the skydive in one of the world's largest helium balloons, which took about two and a half hours to take to the air.

He parachuted from the edge of space, which was close to 10,000 meters, and finally landed safely in New Mexico, USA, after 4 minutes and 22 seconds.

As a result, Baumgartner's jump broke several Guinness World Records, and the most exciting thing was that the top speed of the jump broke the speed of sound, reaching 1173 km h.

Baumgartner has successfully completed the world's first jump with a top speed of 1173 km/h, confirming that the speed of sound has been broken. Other confirmed records have been broken: the highest manned balloon to fly, the highest jump, and the fastest descent.

If it is outside the atmosphere, it will become a human satellite orbiting the earth in space, and finally passing through the atmosphere will be like a meteor and burned into water vapor due to atmospheric friction.

Assuming that outer space is really filled with the same composition of air as Earth, it is obvious that we can easily travel to space, and originally spacesuits and spaceships need to be tightly sealed and need to store oxygen, but because of the weight of spacesuits and the limited amount of oxygen, spacewalks need to be very precise.

Then there will be many strange plants and creatures in space, which will become very wonderful and magical.

Earth is now the only planet where living beings live. One of the peculiarities of the Earth is the oxygen on which it depends. If there is also oxygen on the sun, there may be living things.
