  • I love Sagan!

  • WIN!

  • i have never been so proud to be canadian.

  • Carl makes an interesting point nearing the end of the video... we spend more money on how to destroy others with our weapons then we do on how to fix what we have destroyed already... our planet

  • @purpleproductionftw

    No, more like approximation.  If he memorized it, he would have said 482°C...

  • @KarbineKyle It's not a meteorite until it hits the ground.

  • Dear Carl, Nothings changed really since you left. I write again in another 15 years and let you know what the story is. Cheers.

  • It's like watching an adult talk to a very small child

  • Man if there was one person I could ever sit down and spend 20 minutes with, it would be Carl. I'd learn more in those 20 minutes than I did in all my years in school. And I am a musician saying this, I'd rather sit with Carl than even my most beloved deceased idols of mine.

  • great man, ppl like him should be in governments, if governments would make any sense...
