Its like the end of MiB in a twisted sence.

For all we know we could be like these really small bateria in a larger universe which in the real reality is the size of a pin head - but were so small that we cant see that and think that the unicverse is ever more.

Remember - everyone KNEW the earth was the centre of the universe till they were proved wrong
Everyone KNEW that the workld was flat - untill Chris Columbus found the New World
And every KNOWS that we are the highest life form in the unioverse - at least till we are proven wrong by out own arogance!
