We have Lord Martin Rees to thank for much of what we understand about black holes, quasars, and other distant objects in the night sky. He is England’s Astronomer Royal, and has spent the past fifty years looking deep into the past, to understand the origins of the universe. But for the past two decades he’s also been asking the most difficult questions about the future of humankind, a future made uncertain because of tremendous advancements in science and technology.
