Hmm. . . plays to the end for me. I'd repost it but there are other comments here so it must be working for others too. Try from another machine or at another time and if it still doesn't work I'll repost it.

Silicon is a semi-likely candidate for another basis of life. Showcasing my geekiness, I remember an episode of the original Star Trek where they encounter a species based on silicon. It can bond with itself many times over like carbon and is stable but reacts readily. Just some food for thought.

Rest in peace Carl Sagan.
