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?
May 19 2011: Hello Sean. I know you're leaning towards the multiverse being true, but I wanted to ask a question that assumes that the Universe is all there is (multiverse doesn't exist). It's been explained that the expansion of space is "self-contained" but our intuition of course fails us miserably when trying to visualize this because our brains always assume that an expansion is expanding into some pre-existing volume. Do you know of any way on how to best visualize a "self-contained" expansion?
