How will our death be realized if we fall into space void?

We lose our lives if we fall into space, we all agree. But the question of how this death will always be a matter of debate.

There are many different scenarios in many different sources related to dying in the void of space. What kind of death would they expect us to do if one day actually falls into space? We know that you have not planned a visit to the International Space Station in the near future, but if you think space tourism has begun, you might actually be able to visit space in the future.

First of all, you do not die immediately when you fall into space. Experiments with guinea pigs in cavitation experiments showed that consciousness lasted for about 15 seconds. After 15 seconds you lose your consciousness and you lose your life within 2 minutes.

According to a common belief, space is a very cold place. First of all, space is a gap and an atom is about one centimeter in size. Substance is necessary for heat spreading and heat can not spread in such an empty space. As soon as you get out there, you will not freeze. But you can feel a bit of coolness as the liquids near the deep will evaporate.

There is a rumor that you will explode when you go out. It is partly true, but it is not an explosion that you divide into thousands of pieces as you might think. In space, the air in your body will want to go out quickly. If your mouth is closed, the air can not get out and your lungs can explode.

If your mouth is open, a large part of the air will be partially harmless. But since the blood in your body's liquids and veins will not evaporate immediately and will not go out, air bubbles will form in your body and this will be enough to make blood flow impossible.

We know from research that the natural temperature of objects in space is -270 celsius. An average human body radiates 600 watts of infrared radiation. Which means we've been emitting 600 joules of energy through the glow. How long will a person with a mass of 70 kg and a body temperature of 37 degrees Celsius reach a temperature of -270 celsius?

We can use the formula Q (given heat) = m (mass) * c (specific heat) * ΔT (temperature change) to calculate this. The specific heat of the human body is 3470 J / kg. Therefore, Q = 70 * 3470 * 307 operation without loss of energy required amount of 74.570.300 joule we are. In our case, 600 joules would take 1.5 days to reach -270 celsius compared to what we lost.

But it is not possible to say that this calculation is very healthy. Because our heat will fall and our temperature will decrease and our cooling time will be longer. But in general we can easily say that you will not freeze immediately and your body will continue to cool down for close to 2 days. If you get out there, think of it.
