In the 1980s, when the possibility of wormholes began to capture physicists’ imaginations, there was the inevitable concern about what such objects might mean for causality in an Einsteinian, time-elastic universe. Wormholes through space meant, inevitably, wormholes through time. And so, naturally, people thought of the grandfather paradox, that strange fantasy of killing one’s patriarchs […]
We are four-dimensional beings. As I argue in my new book Time Loops, our behavior at any given moment is shaped not only by the exigencies of that moment and what has preceded it, but also by what comes next; we are informed by things we will learn in our future, not just by what […]
Valentine’s Day, 1900. A group of Australian schoolgirls, all clad in white dresses, are driven by coach to Hanging Rock, an enormous volcanic formation in central Victoria, Australia, for an afternoon picnic. Four girls, including the most popular, Botticelli Venus-looking Miranda (played by Anne-Louise Lambert), defying the orders of the school’s stern headmistress, venture off […]
Check out my article in the March 2018 issue of EdgeScience, on why the extraterrestrial hypothesis should be kept on the table (with some modifications). (And thanks to all my readers who have been patient during my writing hiatus. The book is almost done!)
“We live in a world of opposites, of extreme evil and violence opposed to goodness and peace. It’s that way here for a reason but we have a hard time grasping what the reason is. In struggling to understand the reason, we learn about balance and there’s a mysterious door right at that balance point. […]
Probably because I am thinking about (and trying to finish a book on) precognition and retrocausation and the glass block universe they seem to imply, I keep finding my thoughts returning to a famous Zen koan from 8th-century China. You will have heard it: Master Ma and his student Pai Chang were walking along when […]
The famous “Face on Mars,” first photographed by the Viking orbiters in 1976, was the object of much speculation in the 1980s and 1990s and continues to be. After it was identified by Richard C. Hoagland, the Face became the central icon in a narrative of ancient global destruction—perhaps nuclear war—that, some suggested, may have […]
Even though they were widely panned when they came out and have now been mostly forgotten, I have a soft spot for M. Night Shyamalan’s films from the early 2000s—Unbreakable, Signs, and The Village. Signs, especially, I thought was a satisfying, intimate-scale sci-fi film about alien invasion, but it lost many of its viewers by […]
Few films could better illustrate the workings of precognition than Denis Villeneuve’s excellent new film Arrival, based on a 1999 story “The Story of Your Life” by Ted Chiang. If you’ve seen the trailers, it will give nothing away that it is about a first-contact situation, and the attempt of a linguist, played by Amy […]
Rubbing my temples and squinting, I foresee that no less a science writer than James Gleick will very shortly be publishing a book called Time Travel. Unlike his most famous book, Chaos, which was incredibly forward looking—introducing a whole generation to a really cool new concept, “the butterfly effect” (i.e., the way a butterfly flapping […]
