Не могу не процитировать (англ., нет времени переводить, увы). Некий Roger Wibberley в фейсбуке пишет, какой чудной была бы наша картина мира, живи мы на этой Ио:
"I can't help wondering how different we and our history would have been had we lived on Io rather than on Earth! Here on Earth we look mostly at an open blue sky with a small but bright Sun shining during daylight, and at a dark open sky (with small stars and a 'smallish' moon) during the night. Little wonder that early explanations and interpretations were that the universe revolved around *us*, and that we were the centre of the known universe. We could even accept that the Earth was flat.
But if (as it seems on Io) what one saw when looking upwards was a wall-to-wall, horizon-to-horizon view of a clearly different body with storms and cloud formations quite separate from our own world (but close enough to dwarf us) we should hardly have ever thought that we were the centre of anything, or of as great a significance as the large luminous body that was near to us. Perhaps we should have thought of the *sky* as our God? But perhaps, also, we should never have known as much as we do about the visible Universe - if only because our parent planet did its best to prevent us from seeing any of it.
