Where would a person drift if he died in space?

It depends on which gravitational field you are pulling at the time - control.

In near-Earth space, eighty percent of them will eventually fall back to Earth.

The next day it quickly merges with the sun, and you become a part of the sun – you are light, you are electricity, you are a fascinating myth.

Near-black holes are quickly dragged into it and instantly compressed by billions of times (i.e., a dust that is indistinguishable to the naked eye is 10,000 times larger than you).

Exoplanets with a high degree of civilization may be resurrected by little girls and become their toys; They may also be bred in captivity to become their meat eaters. Good luck!

Look at the environment he is in, there is a gravitational equilibrium zone between the planets, if he dies here, if he dies here, if he is not forced, he will always be still there and will not move, until he receives a force, if he moves on this belt, he will continue to move along this belt until he enters the next gravitational field, and the gravitational force changes the course of motion. Now, let's talk about another situation, he does not die in the gravitational equilibrium zone, even if he deviates a little, he will be affected by the gravitational pull of a star, and will move in an elliptical circle around the star, and get closer and closer to the planet, until he is completely bound by its gravity, and falls into it, and the bones will be reduced to nothing.

Popular science universe exploration knowledge.

Because people will be weightless when they are in the space environment, and weightlessness means that the object loses the effect of the gravitational field, when the object is in a weightless state, the object will not be affected by any external gravity field except its own gravity, so the person will float.

Weightlessness is not the result of the disappearance or drastic reduction of gravity (in fact, at an altitude of 100 km, the Earth's gravity is only about 3% less than the Earth's surface). The phenomenon of weightlessness mainly occurs in orbit or in space, or in aircraft that performs parabolic flights, or in some other abnormal conditions (far from the planet or heavy objects) of objects or people. The phenomenon that the pressure of an object on a support is less than the gravitational force experienced by an object is called weightlessness.

It will not fall in space, it will become a satellite of the earth, floating in space. If you want to drop it, you will also fall on the ground and break it into a meatloaf.

The universe outside the Earth's atmosphere, the whole space outside the atmospheric space. Physicists divide the atmosphere into five layers: the troposphere (sea level up to 10 km), the stratosphere (10 40 km), the mesosphere (40 80 km), the thermosphere (ionosphere, 80 370 km) and the outer atmosphere (ionosphere, above 370 km).

About 3.4 percent of the atmosphere above the Earth is in the troposphere and 97 per cent below the stratosphere, the outer edge of which is the maximum limit for aircraft to fly with air support. Some high-altitude rockets can enter the middle layer. The lowest orbit of an artificial satellite is within a thermolayer, and its air density is 1% of the Earth's surface.

Air continues to exist at altitudes of 10,000 km, and there are still airborne particles even at altitudes of 100,000 km. From a strictly scientific point of view, there is no clear boundary between airspace and outer space, but rather a gradual convergence.

The Scientific and Technical Subcommittee of the United Nations Committee on the Peaceful Uses of Outer Space noted that it was not yet possible to come up with precise and lasting scientific criteria for delineating outer space and airspace. In recent years, there has been a trend towards the minimum altitude of satellites off the ground (100,110) kilometres as the minimum limit for outer space.

Childish, where can space fall? It's still space.

Floating is due to weightlessness.

In fact, the current astronauts have not left the range of gravity, whether it is the earth, the moon or the sun, but because the astronauts are doing circular motion, this movement needs centripetal force, and the gravitational force at this time is exactly the same size as the centripetal force required, so you see that at this time, the astronaut seems to be floating, in fact, he is still affected by gravity, this phenomenon is called weightlessness.

Earth's gravitational pull.

Weightlessness in the sky. Weightlessness means that the object loses the effect of the gravitational field, and when the object is in a weightless state, the object will not be affected by any external gravitational field except its own gravity. The so-called gravitational force is a component of the gravitational pull of the earth on an object, and the magnitude is almost equal to the gravitational force.

The magnitude of the gravitational force is directly proportional to the mass and inversely proportional to the square of the distance. In the case of a celestial body with a certain mass, the farther away an object is from it, the smaller its gravitational pull is, i.e., the smaller the gravitational force, and at a sufficient distance, its gravitational pull is negligible. But there is more than one celestial body in the universe, and the gravitational pull of many celestial bodies forms a gravitational field.

The situation of an astronaut in weightlessness in the universe is basically the same as that of a person who cannot play in water falling into deep water and floating matter in the atmosphere. The reason for this is that astronauts in space will be weightless in space instead of falling under the conditions that allow the bearing capacity of space materials such as pure gas, which have not yet been detected.

See how long I can float.

The phenomenon of weightlessness occurs mainly in orbit or in space or in some other abnormal conditions (far from a planet or a heavy object). Weightlessness is not that the gravity is zero, but that the gravity (also called the apparent gravity measured in real time) is less than the actual gravity (based on the average gravity of the earth's surface) When the acceleration of a near-Earth object is downward, its apparent weight is less than the actual gravity, it is said to be in a weightless state, and when the object accelerates downward with acceleration g (that is, free fall), it is called a completely weightless state.

Drink a bottle of beer to crush the shock.

Gravitational force also exists in space, but the centripetal force and gravitational force generated by the rotation of people and spacecraft around the earth are a pair of balancing forces, so people float. If there is no gravitational attraction in space, the spacecraft will be farther and farther away from the Earth and will not revolve around the Earth.

The reason why people will float in space is that they are in a state of weightlessness, that is, if they still don't feel the weight, the human body will float in the air, and at this time it is not that there is no gravitational force around it, but these gravitational forces are very small and cannot make themselves stand.

The earth has a gravitational pull, so people are able to walk upright on the earth. And when man leaves the earth and goes to outer space, there is no gravity, there is no atmosphere, only buoyancy.

Take a spaceship revolving around the earth as an example, the whole has centripetal acceleration, the centripetal acceleration points to the center of the earth (the object has downward acceleration), gravity is all used to provide centripetal acceleration, and the person has no pressure on the support and is completely weightless.

Summary. Hello dear. Soviet cosmonaut Vladimir Komarov, the first human to die in the vast sea of stars.

Hello dear. Soviet cosmonaut Vladimir Komarov, the first human to die in the vast sea of stars.

China does not have the first astronaut to die, up to now, the list of Chinese astronauts includes Yang Liwei, Fei Junlong, Ye Haisheng, Zhai Zhigang, Liu Boming, Jing Haipeng, Liu Wang, Zhang Xiaoguang, Deng Qingming, Li Qinglong, Wu Jie, Chen Quan, Zhao Chuandong Nianjian, Pan Zhanchun, Chen Dong, Liu Yang, Wang Yaping, Tang Hongbo, Ye Guangfu, Cai Xuzhe, no one sacrificed. Recently, the Long March-2F Yao-14 carrier rocket carrying the Shenzhou 10 Xianzi 4 manned spacecraft was ignited and launched at the Jiuquan Satellite Launch Center, and about 577 seconds later, the Shenzhou 14 manned spacecraft and the rocket were successfully separated and entered the predetermined orbit, the flight crew was in good condition, and the launch was a complete success.

Tao Chengdao was the first person to think of using rockets to fly into the sky, and was known as "the first person in the world's aerospace". In his later years, Tao Chengdao returned to the service to tie 47 self-made rockets to the buried chair, sat on it, held two large kites in both hands, and then asked someone to ignite and launch, envisioning the use of the thrust of the rocket and the power of the kite to fly. Unfortunately, the rocket **, Wanhu also gave his life for this.

Planets are gravitational, but in space gradually away from the earth's gravitational field, and then the sun's gravitational force on people is very small, negligible, so it has reached a state of almost no resistance, for example, when astronauts land on the moon, you will find that there is gravity on the moon, and the gravitational force on the moon is about 1 6 of the earth's gravity, but he still has it, but people will feel much lighter than the earth on it. At that time, the gravitational pull of the moon and the force exerted by humans also reached a balance, so they were still able to move normally on it.

The reason why people float in space is because of weightlessness. The space station can be fixed and immovable because of gravity equipment, so that the space station is in a gravity environment.

The astronauts in the space station will not float around the earth at high speed because of their inertia, and because of their high speed and inertia, they will not float around and will travel in a certain orbit.

Because there is no buoyancy and no gravity in space. It will run at a constant speed and look like it is stationary. Actually, it's just relative.

If a person dies in space, there is a good chance that the human body will freeze and then slowly decay or be properly decomposed. With the development of science and technology, human beings have begun to explore the mysteries of the universe. The future of space travel is getting brighter and brighter, and humanity is embarking on a journey into space.

If a human accidentally dies in space, the body will not decay and decompose like on Earth, but will be slowly frozen first, and then begin to gradually decay or decompose.

If an astronaut is not wearing a spacesuit, then the astronaut can easily die quickly due to lack of air pressure. Oxidation cannot occur in space, so the body does not decay, but freezes. When the corpse is frozen, all biological processes of the corpse are inhibited, and the corpse does not decompose.

However, most astronauts wear spacesuits, so when a person dies in a spacesuit, the bacteria in the body will still decompose the body and slowly decay the body.

The corpse of the astronaut will float in space, and the spacesuit on the body will be decomposed by the radiation around him in the process of drifting. This process of decomposition can be very long, and once the spacesuit is destroyed, the body will be quickly destroyed. So in either case, once you die in space, you will eventually die.

Space is a mysterious and dangerous place, and it is difficult for humans to survive in space. Therefore, if human beings want to enter space, they must be in the space capsule, and if they want to enter space, they must also wear spacesuits. Therefore, astronauts need to go through rigorous training before entering space, and only after passing the training can they have the opportunity to enter space exploration. Seep God.

There are many things that happen to people in space:

1. There will be no blood boiling or **. When the external environmental pressure is 0, the blood pressure can be maintained at least around 75 Torr, and the boiling point of water at this pressure is 46 degrees Celsius, so the human body temperature is not enough to boil the blood;

2. The human body will not freeze or frostbite. Although the space environment is very cold, because there are few molecules in space, close to vacuum, it is a good heat insulator, and people who are exposed to it for a short time will not feel cold and heat, and those who are exposed to it will not leave the human body in a very short and permeable time, and will only feel slightly cold because of the evaporation of water on the body surface, but will not freeze to death immediately;

3. Will die of lack of oxygen. In the case of insufficient oxygen supply, consciousness can be maintained for about 9 to 11 seconds, after which the body becomes paralyzed, convulsed, or more severely damaged;

4. It will die of sunburn. If ** is exposed to the intense ultraviolet radiation of direct sunlight without any protection, very severe burns can occur and even lead to death;

5. There will be other injuries. Damage to the brain and nervous system, leading to neurological problems such as blindness or visual impairment.
