Hi friends steemis

The topic is too big and we can not talk about it in one post

Therefore, we will deal with other posts in which we complete the subject

We will start with the first facts

1-  If you go into outer space without a helmet, it will not explode or boil, but you will snatch and die

In space, your head will not explode or your eyes will come out of their place and you will not freeze until ... you will only slowly embrace

What would happen if an astronaut outside his vehicle lost his helmet? If you ask the films, the answer will be to see him go out of his place and his head will explode and boil his blood as well, and perhaps it is partly logical that the loss of the helmet means the lack of atmospheric pressure of the body fluids and thus reduce the evaporation temperature to begin boiling immediately

But things are not that simple. The body is able to resist the pressure differentials caused by the lack of external air pressure easily. Even freezing will not be really frightening because your body temperature will only go to radiation because there is no transport medium. Oxygen is therefore suffocation in effect

2- If you want to become taller, a trip to space may check you out

Near-zero gravity means a lack of pressure on the joints and bone spacing, resulting in increased length in space and joint pain on the ground

The presence in space of your height will certainly increase, albeit temporarily, with a side-view: severe pain!

In cases of zero gravity, the joints do not experience the usual pressure caused by the weight above. This means that the joints expand and the bones diverge even slightly, leading to an increase in length.

But do not forget that the spine is one of the most densely populated areas of the body in terms of the number of joints, and with the stretching and the density of nerves present there, when returning to the conditions of natural gravity and compression of the paragraphs again there is a significant risk of disc between discs or nerve compression.

Of course, the danger is not just pain, but it can also have serious health consequences

3- Hide between asteroids to escape? Not a logical choice

Asteroids separate them from each other so vast distances that some of them are difficult to see from another surface

In science fiction movies and in the frantic pursuit of spacecraft, a familiar scene is often repeated. The fugitive is used to enter the "asteroid field" to conceal its impact and to hide its place from its chase vehicle. These asteroids seem very close to each other and almost impossible to navigate. Among them.

But the reality is very different from this. Contrary to what the movies have seen, asteroid belts - whether those of the solar system or others - are never dense. They are almost empty. According to NASA, the accidental collision of a passing ship in the region with one asteroid does not exceed one billion, So avoid the idea of escaping to the asteroid belt if you find yourself on board a vehicle with lots of Storm Troopers chasing you with their vehicles.
