In The Washington Post, James Trefil , a professor of physics at George Mason University, provide an interesting perspective on The Grand Design by Stephen Hawking and Leonard Mlodinow.
In "The Hitchhiker’s Guide to the Galaxy," Douglas Adams famously had his characters ask a computer to provide the ultimate answer to "Life, the Universe, and Everything." As Stephen Hawking and Leonard Mlodinow point out in their book "The Grand Design," the computer’s response — 42 — was less than helpful. Hawking, who needs no introduction, and Mlodinow, a Caltech physicist with a string of excellent books to his credit, have taken on that ultimate question in a somewhat more rigorous form by asking three related ones:
Why is there something instead of nothing?
Why do we exist?
Why does this particular set of laws govern our universe and not some other set?
