This video comes from our new TED-Ed channel on YouTube.

Now available as a full-length version (12 minutes): TED Curator Chris Anderson shares his obsession with questions that no one (yet) knows the answers to. An introduction leads into two big questions that Anderson (and all of us) pondered as a kid and still do … Length: 12:08.

(The film is also available in three separate parts: an introduction and the two questions as separate films: Why can’t we see evidence of alien life? on.ted.com/AlienLife and How many universes are there? on.ted.com/HowMany. It’s all part of a TED-Ed series called Questions No One (Yet) Knows the Answers To.)
