  • May 19 2011: Sean, you stated that: "...empty space essentially lasts forever (but) since empty space gives off radiation there's actually thermal fluctuations and it cycles around all the different possible combinations of the degrees of freedom that exists in empty space."

    Does this make life possible in the empty space era?
