Question:
Can you have a livable environment without gravity?


Replies:
Since many people have lived in zero gravity for months at a time, I would have to say yes. If you mean that the "environment" is a self- sustaining ecosystem, no one has tried it yet, but the "Biosphere" experiment in Arizona was an attempt to see if a small self-contained ecosystem could sustain human life for more than two years - it worked. Of course they had gravity there, so it is not a complete test of your question. You might be interested to read some of the information about biological experiments conducted on the Space Shuttle in NASA's "Space Link" bulletin board.
