Girl Dancer in Bali / バリ島の少女ダンサー


Astronaut Chiaki Mukai of JAXA talked about her spacewalk experience at a debriefing session at Tokyo University of the Arts in October 2003, “The body needs to be attached to somewhere in order to make a base. I wanted to connect to something even with a single string. Isn’t that the essence of human beings? Sometimes I feel sick. I think space needs artificial gravity.” Her recognition seems to be appropriate and right, and it is an excellent reference for me to think about physical and brain problems in less-gravity environment. Not many astronauts say this point.



Although it is not a scientifically proven case, as an example similar to Mukai’s remark, there is an interesting episode “Loss of sense of direction of a girl dancer in Bali” on the ground. In Bali dance, the relationship with the sacred mountain in the center of the island is important, and for a young girl dancer, when she blindfolds her and loses her “direction” towards the sacred mountain, she immediately changes her “posture” and can’t continue her dance. Then she takes her blindfold and asks her to confirm the “direction” of the mountain, she begins to dance again. This is because for a girl dancer, the state of losing her relationship with the sacred mountain is close to the state of being placed in a less-gravity environment, the “posture” is broken and the dance cannot be established. At that time, as if her brain function was paralyzed, holy mountains existed in all directions, making her expect to be in serious sensory confusion.



As the physical and brain problem, if such a difficult problem like the humans in less-gravity environment or a girl dancer in Bali arises, how to solve it?



I have tried to solve this problem using Space Tube which can be regarded as a pseudo less-gravity environment. In the first place, what is “Posture” for humans in relation to the environment? How is “Posture” expected to change in relation to gravity? Space Tube has a certain solution to these questions. Above all, in Space Tube we can study for ourselves that the support from space and things is indispensable for forming a “posture”.

私は、この問題解決を擬似的無重力環境と見なせるスペースチューブを使用して試みてきた。そもそも人間にとり「姿勢」とは、環境との関係において何であったのか? 重力との関係により「姿勢」はどのように変化することが予想されるのか? チューブ空間はこれらの問いに一定の解決を与えることができ、何よりもチューブ空間の中では、「姿勢」の構築のためには空間やモノからの支援が不可欠であることを、身をもって学ぶことができる。
