How To Build A Time Machine

I couldn't think of a better title than that — because it is the title of Stephen Hawking's Daily Mail article. And he is really going to tell you how to build a time machine! And you are going to need a wormhole, btw.

It is absolutely worth reading because it says as much about Hawking as it does about the space/time continuum. After describing himself as a "dreamer" because cannot move, Hawking makes the case for his own interest in bending time:

Time travel was once considered scientific heresy. I used to avoid talking about it for fear of being labelled a crank. But these days I'm not so cautious. In fact, I'm more like the people who built Stonehenge. I'm obsessed by time. If I had a time machine I'd visit Marilyn Monroe in her prime or drop in on Galileo as he turned his telescope to the heavens. Perhaps I'd even travel to the end of the universe to find out how our whole cosmic story ends.

Hawking has always seemed one of the world's more personable geniuses. It's charming to read a scientist letting his mind run — and this article, wormholes et al, confirms he is a man of big dreams, as well as a hefty brain.
