Journey when people fall from the universe to Earth

What happens when people fall from space to Earth?

Fly to Karman Line , the boundary representing the starting point of the space, 100km from the Earth's surface, and find out what happens when we jump out of the ship in the video below.

First, people will lose consciousness immediately. Brain cells need oxygen continuously but the space here cannot be met. The human brain is hypoxic and almost inactive. If severe, this can also lead to seizures, coma, and even brain death.

Friction when falling quickly at this height will burn the skin.

On the thermal floor of the atmosphere , we must also be exposed to strong X-rays and ultraviolet rays from the Sun. If this is not enough to lose lives, we may start vomiting due to radiation poisoning .

When going to the middle floor 50-85km from Earth, things don't get better. The temperature here is especially cold, close to -100 degrees Celsius, causing severe body burns. In addition, friction when falling quickly at this height will burn the skin.

This atmosphere is also where meteorites decay. They rushed down and followed the trail of dust and light behind. If you fall through the atmosphere, you may become a meteor version of the human version.

Next to the stratosphere about 15-50km from the Earth's surface. Blood will start to boil at an altitude of about 23km. With this atmospheric pressure, the liquid boils at a lower temperature due to the change in pressure in the liquid, causing the molecule to move more freely between the liquid and gas states.

The lower the pressure, the higher the boiling rate. With pressure at this height, blood may boil . This phenomenon can also occur with other fluids in the body such as stomach acid and urine.

The troposphere is probably the least harsh layer in the atmosphere. You start falling into the troposphere at an altitude of about 15km. Here, the oxygen-rich atmosphere is much more than enough for us to recover consciousness.

The world has not recorded any case falling from the point 100km from the ground but some people have survived falling from very high.

1. Pilot Alan Magee in World War II survived falling from a height of about 6 km and plunged into a glass roof to help reduce collisions.
2. Flight attendant Vesna Vulovic is on the plane that exploded at a height of 10km. Vulovic still lives after falling to the ground in part of the plane.
