Stephen Hawking on Where Did We Come From?

Here is a video of Stephen Hawking talking at a TED conference this past February. In his speech Professor Hawking discusses the following questions:

1. Where did we come from?/How did the Universe come into being?
2. Are we alone in the Universe?/Is there alien life out there?
3. What is the future of the human race?

I followed his discussion on aliens but about half of the stuff about the origin of the Universe flew over my head.

I've watched a number of good videos lately. I'm thinking about posting some more. Let me know if you're interested.
