Yes
Stu that was funny!
I liked his comeback on if aliens had built the pyramids why then didn't they leave a spanner or titanium or something.
I really like the way he explained curved space using earth as example if you walked from the equator to the north pole in a straight line it's actually curved even tho it feels like you walked a straight line and putting that into context of how the universe is curved and not really straight. I get it so much better now.
Andrew, many thanks, I'll chase that up.
I'm listening to the show again, this time on radio and yaaay caught up with the first 20mins I missed on the live stream. So much info to take in, one really needs to listen to it twice and then some. What a great show!
