For question 5. As a child, your voice was recorded for the phonograph discs that were attached to the Voyager spacecraft, which feature the sounds of Earth, just in case the spacecraft ever wandered by an extraterrestrial civilization. Do you think they ever will? Also, if the Voyager craft were being made today, would we include an iPod instead?
I want to say that no, I don't think we would. We might send a dvd but actually a phonograph is probably still a good idea to send. The beauty of the phonograph is that it is a fairly simple device and any ETI finding it would only need to work out that you put a needle in the groove and spin the disc to get the information out. Of course it would be very quiet without amplification and I don't know how we could convey the correct speed to spin it at, but the basics are relatively easy. The way we store information on a dvd would be as obvious as a phonograph is and I expect today we would send a dvd also, but getting the information out of it requires more processing than playing the phonograph.
Sorry, I get these urges sometimes. Also, I'm sitting on the floor because there is a cat in my chair.
The interview itself is interesting and I need to check out some of Sagan's books. Both Sagans, actually.
