Slightly off-topic, but—how mercilessly correct he is about physics of our space-time. We all know the universe is expanding, but many consequences of this phenomenon are not obvious—such as that after some time we'll be unable to see (and therefore ever reach) even nearby galaxies, since they're constantly getting farther and farther away. We'll be completely alone forever, and future scientists would have completely wrong picture about universe in such an absence of information. Thinking about that, we already miss a lot of information because of red shift… There're facts potentially explaining the eternal question ‘about universe and everything’, but they are slipping away from us, crossing the event horizon never ever to be learned about. Not a fun thing to know. Personally for me that was a discovery thanks to the explanation by Lawrence Krauss in his ‘A Universe From Nothing’ popular talk (http://www.youtube.com/watch?v=7ImvlS8PLIo http://www.youtube.com/watch?v=7ImvlS8PLIo).
