I pretty much read anything that mentions, quotes, or is written by Stephen Hawking, the great popularizer of physics. I have to thank him, too, for helping me expand my appreciation of the universe and the God who made and is making it still. I doubt Hawking is a believer in the traditional sense, but I have a feeling he may be a mystic of another sort. Take this from a recent piece on time travel: "Although I cannot move and I have to speak through a computer, in my mind I am free. Free to explore the universe and ask the big questions, such as: is time travel possible? Can we open a portal to the past or find a shortcut to the future? Can we ultimately use the laws of nature to become masters of time itself?"
Questions worthy of any mystic.
