Science and philosophy
What are black holes?
How did the universe begin?
Are there alternative universes?
What are stars made from?
How old is the universe?
Can the laws of physics change?
What is dark matter?
I haven't got a clue how to answer any of the above questions and there are many more in Stuart Clark's book The Big Questions which I also cannot answer. If you are like me, you may want to grab a copy of Clark's book and get reading. The author is a professor of philosophy at the University of Cambridge so he probably knows what he's talking about. I suspect it is all a bit beyond me so I will wait for one of you to pop in and enlighten me in words of one syllable.
