Tomorrow I’m shooting all day for a TV show that is going to focus on the idea of alternative universes (or parallel universes, if you prefer). Should be fun. The setting at least will be interesting (more on that later) and it ought to be interesting to see how the writer puts all the material together into a coherent narrative. Part of my job will be to try to emphasize that while parallel/alternative universes show up a lot in actual scientific discussions (and have done for a long time), we have not yet had anything like a good observational or experimental reason to believe in their existence anywhere other than in our imaginations. It’s vital to get this across (I hope they don’t just edit it out) because people are so willing to believe in many half-baked fanciful ideas – and this is one of them – and when they show up in a science documentary (this is (again) for the History Channel’s “The Universe” series, which has been very good) with actual scientists being quoted, one should be especially careful (as we were on the “Cosmic Holes” episode (with different filmmakers), which has proven to be rather popular, and is full of speculative ideas like travel using wormholes and time machines right alongside equally fantastic-sounding things, like black holes, which are in fact a scientific reality). The rest of my job will be to talk about some of the places where the idea shows up in modern thought, some of the reasons why, and some of the opportunities for solving various challenging problems (and maybe creating a host of others!!) can be afforded by such ideas.

All that aside, this reminds me of something else entirely – Do you ever have those days when you feel like you’ve accidentally stepped sideways into an alternative universe? I do. Recently, I had a huge dose of it. Sit back and I’ll tell you the story…[…] Click to continue reading this post →
