Wonderful book. I’ve just joined a book club with friends and this is the first book. Here are my thought/questions/memorable quotes that I plan discuss with the other guys.

1. What is nothing?
2. What exactly is a singularity. What is a ‘single point’
3. Black hole chapter went over my head . Maybe Stephen got a bit carried away with ‘ his thing’. Does it matter? Why is it a “Big Question”
4. If I was caught speeding by the police and the evidence was “we saw you outside the fish and chip shop travelling at 50mph in a 30 zone”. Doesn’t this undermine Heisenburg Uncertainty Principle where you can’t measure precisely position and speed at the same time? Would the judge listen? :-)
5. “ if you want to apply for a grant to study time travel you have to call it “closed time curve” otherwise you’re labelled a crank
6. “ I’m pretty sceptical of conspiracy theories as I believe cock- up theory is much more likely” ( in the context of time travel and why nobody has come back from the future to tell us about it)
7. “If you look behind every exceptional person there is an exceptional teacher. When each of us thinks what we can do if life, chances are we can do it because of a teacher”
8. Our nearest black hole is 2800 light years away but somehow we can study them. That’s amazing
9. “ I think the survival of the human race will depend on its ability to find new homes elsewhere in the universe.”
10. “ I would hope to be remembered for my work on black holes and the origin of the universe. But above all I would like to be remembered by my children and grandchildren as a great Dad and Granddad”
