Carl Sagan's Cosmos: Episode 12-Encyclopedia Galactica

I uploaded Carl Sagan's Cosmos because this is what the internet, at its best, is all about. But I never expected the comments I would see! It seems like every day I get comments from people talking about how special Carl was, what he meant to them, how he changed their lives, etc. Every comment brings a smile to my face. I'm very proud to say the comments to these videos have become a virtual shrine to a great man who is obviously still missed by millions.

As for me, I first watched Cosmos when I was 10 years old. It had a profound impact on me that lasts to this day. For years, I thought I should become a scientist as a result. That never worked out, and I ultimately chose a very different career path, but Carl's thinking still permeates my intellectual character: his rationality, his skepticism, his deep-felt love of humanity, and, most importantly, his enduring optimism.

Enjoy! And please keep those wonderful comments coming!

Conquer. And would hopefully be driven by similar desires that the smartest of us have. The desire to understand, and figure things out.

Unlike the idea proposed by Hawking, I think that in order to gain the level of technology necessary for traversing star systems, that being would have had to have evolved beyond its desire to con

@WestVirginiaRebel Well, there will always be those kind of species. However, it seems more likely that a wise, benevolent species would evolve high enough to journey enough stars to find us.

@calito44 In my opinion, It's just as likely that a civilization will fall into non-peace after attaining galactic travel as to stay peaceful. Sure, it's probably that they'll need to be peaceful at one point, but there's no saying they'll stay that way.

@WestVirginiaRebel Perhaps because a lot of people think(me included) that in order to advance to the other level( galactic and interstellar) we have to understand that living in harmony is the key to suceed. Extrapolating this thought then we assume that only civilizations that made that understanding jumped to the next step. That civilizations that never made it fell into self destruction. We could be wrong.... but that is your why :)

Why do people always assume that an interstellar civilization would be peaceful? Wishful thinking, perhaps? As long as intelligent creatures have free will, there will be conflict over resources, territory, etc. esp. in a "crowded" and expanding neighborhood. At the very least there might be pirates and rogue raiders.
