100,000 meters is equivalent to a height of 100 kilometers, if a person jumps from such a high parachute jump, the probability of his survival is almost zero. Atmosphere is divided into many levels, each level of environmental changes are different, directly affecting the human living space. There are different layers of the atmosphere at different distances from the Earth, so we can determine how high up the atmosphere is and what kind of threat it poses to human beings.

When a person jumps from a height of 100 kilometers, we can use this 100-kilometer figure to see what kind of atmosphere exists at that height. First of all, the closest to the earth is the air current layer, the height of this air layer is about 17 kilometers away from the earth is about the height of the air layer, this air layer of the environment for human beings is no harm, and with the up is the stratosphere, the intermediate layer and the current layer.

The altitude of the stratosphere is about 50 kilometers, and the probability of survival is relatively high if a person jumps down from this altitude, because the airflow and the environment are relatively mild, and the human body has not yet adapted to it. As the altitude increases to about 100 kilometers, the air layer is basically between the middle layer and the current layer. This layer of air brings more damage, because the air flow is very big, and the oxygen is very low, and the ultraviolet radiation is very big, this environment is very great for the human body.

By jumping from such a high intensity air flow, you may lose consciousness, your body's function will be greatly damaged, and you may not fall to the ground when your body can't stand the pressure and directly enter into the state of death is also very normal. Therefore, if you jump from 100 kilometers down then basically the probability of death is 100 percent, and for the most suitable height of the skydiving should be controlled within 17 kilometers is the best.
