Lex, you did not say in the introduction to your talk that in our country Martin Rees is the current Astronomer Royal, which is a very prestigious and notable post in the United Kingdom, which goes back for centuries, to 1675 when Charles ll  founded the Royal Observatory at Greenwich!  He has been a hero of mine for a very long time.  Well done for getting him on your podcast!,(reply>), I knew he was a vampire! Lord Dracula... If you folks are unaware, the royals are serpent seeds that are Japhetite from Cain's lineage (and the serpent in the garden who seduced our mother). mhmm,(reply>), He’s is such an exemplary British gentleman, educated, knowledgeable and a superior personal conduct and eloquence. This is the one thing to admire most about British culture. Greetings from Germany
