1.) Would it, in theory, be possible for life to develop in such an enclosed space? I'm thinking funghi might be expected, or maybe some insects.
2.) There will not be any life, regardless of the answer to 1 - so, that considered - would the air be stale or fresh?
Thank you in advance for your help.
EDITED for title line. I had one, posted to the wrong journal and forgot to C&P it over. >_< Sorry.
