Astronauts stretch when they go out. What is the real reason for this?
The day we passed, Japanese astronaut Norishige Kanai announced that it was 9 cm from the official social media account. The astronaut 9 cm in space at the International Space Station (ISS) for about 3 weeks has created excitement among researchers as well as us. As you know, it turned out to be a misunderstanding afterwards, and it was understood that Kanai was 2 cm longer than 9 cm.
Despite being wrong about the cannula length, 2 cm in length within 3 weeks is not bad for the ears. Moreover, this elongation can reach almost every astronaut who has spent a certain amount of time in space. Well, what is the real reason for this extension? Why are we so long when we go out?

Some things are very complicated, but there is a very simple explanation. Gravity. The power of gravity in the world is always attracting us towards the end. This prevents the gap between our joints. Since we do not have such a gravitational force when we go out, our joints are relaxed and can be extended by about 2-3 cm.
This event has been proven experimentally between Scott Kelly and twin Mark Kelly, who have been in space for the longest time in the past. When Scott was out of town, Mark remained in the world and many things were compared, such as the length and weight between the two. As a result of these tests, Scott, who normally runs away from twins of the same size, is 2 cm further from Mark when he returns to Earth.
According to NASA, this is not the only reason why gravity is the biggest cause. Spending long periods of time in a zero weighted environment, such as an ISS, causes the spinal cord to stretch. When you spend a lot of time in space, you do not only lengthen, but also your shoulders. The best example of this can be shown as 'puffing up in space'
