i know this is a weirdo post, but sometimes i think about this: even in our miniscule existence (look up carl sagan's cosmic calendar), we have made a lot of advancements. would you argue that there is a point where it is no longer possible to make advancements? could you say that given enough time, anything might be possible? imagine what would be possible if humans were continuously alive since the beginning of even just our solar system. ABSOLUTELY INCREDIBLE: http://school.discovery.com/schooladventures/universe/itsawesome/cosmiccalendar/page2.html notice the "1 second before midnight...voyage of christopher columbus." OUR LIVES LAST A FREAKING INSTANT.
