EVERY year, the American Institute of Aeronautics and Astronautics awards prizes for the best papers presented at its annual conference. Last year’s winner in the nuclear and future flight category went to a paper calling for experimental tests of an astonishing new type of engine. According to the paper, this hyperdrive motor would propel a craft through another dimension at enormous speeds. It could leave Earth at lunchtime and get to the moon in time for dinner. There’s just one catch: the idea relies on an obscure and largely unrecognised kind of physics. Can they possibly be serious?

The AIAA is certainly not embarrassed. What’s more, the US military has begun to cast its eyes over the hyperdrive concept, and a space propulsion researcher at the US Department of Energy’s Sandia National Laboratories has said he would be interested in putting the idea to the test. And despite the bafflement of most physicists at the theory that supposedly underpins it, Pavlos Mikellides, an aerospace engineer at the Arizona State University in Tempe who reviewed the winning paper, stands by the committee’s choice. “Even though such features have been explored before, this particular approach is quite unique,” he says.

Unique it certainly is. If the experiment gets the go-ahead and works, it could reveal new interactions between the fundamental forces of nature that would change the future of space travel. Forget spending six months or more holed up in a rocket on the way to Mars, a round trip on the hyperdrive could take as little as 5 hours. All our worries about astronauts’ muscles wasting away or their DNA being …
