This survey has been established to generate an archive which will help me to illustrate and understand the cultures of knowledge in science, believe, emotion... There's a layer above the earth; a shell, which cannot be crossed easily and which transforms those things which pass it towards the ground or towards space. Everything changes during the passage, as well in theory as in physical, chemical, ideological condition. The sky (better to use the german term „Himmel“, which includes both sky and heaven) is a locality and an idea; utopia and a condition. By now it has become a place, which expands human's geographical limitations towards endlessness; he or she now is able to enter and examine it either in person or representatively. A direct access to the sky above is reserved for only few, spaceman and -women or those who have access to advanced technology. In contrast to that, still every single person is able to investigate the sky by the use of his or her own senses, for it is nearly everywhere and always to be seen; always present at least. It is the perfect field of expertise for those who want to compare epistemic processes, emotional effects and so on in a maximum range. Just something, almost noone can evade from and everyone has at least experienced in some way. I would like to document spots around the world where something came through the Earth's atmosphere or maybe is constantly coming through it.
