Can Galactic Empires Exist Without Faster-Than-Light Travel?

My newest science fiction novel, Lockstep, was recently serialized in Analog magazine. Reactions have been pretty favourable — except that I've managed to offend a small but vocal group of readers. They're outraged that I've written an SF story in which faster than light travel is impossible. » 3/31/14 4:00pm 3/31/14 4:00pm

Captain the starship of your dreams with Faster Than Light's expansion

Anyone who grew up watching any version of Star Trek has dreamed of commanding a Federation vessel. And Faster Than Light is an amazing PC game that lets you do just that — plus a free expansion will let you add more weapons, drones, and alien ships. » 12/25/13 7:00am 12/25/13 7:00am

This may be the best scientific paper abstract ever written

The title of the paper: "Can apparent superluminal neutrino speeds be explained as a quantum weak measurement?" The abstract? See for yourself: » 7/10/13 7:20am 7/10/13 7:20am

Neil deGrasse Tyson to host tonight's Isaac Asimov Memorial Debate,…

Every year, in memory of Isaac Asimov, the American Museum of Natural History invites leading scientists from around the world to debate the finer points of questions and problems that are emerging at the frontiers of scientific discovery. » 3/20/12 8:45am 3/20/12 8:45am

Physicists explain technical glitches behind those faster-than-light…

Yesterday, rumors were circulating that last year's faster-than-light neutrino results had been undone by a simple mechanical mishap: one of the fiber optic cables connecting a GPS unit to a computer may have been loose. » 2/23/12 8:00am 2/23/12 8:00am

Faster than light neutrinos may have just been disproven

This could be it, folks. Last September, physicists watching neutrinos travel from the CERN laboratory in Switzerland to Italy's Gran Sasso laboratory announced that they had detected the subatomic particles making the trip 60 nanoseconds faster than the speed of light dictates is possible. Now, rumors are flying that… » 2/22/12 2:26pm 2/22/12 2:26pm

One weird theory could make anti-gravity and faster-than-light travel…

So we've had neutrinos that traveled faster than light — or at least, that result hasn't been invalidated yet. But how soon can we get spaceships that can travel to other star systems without traveling at faster-than-light velocities? The answer might lie in a relatively little-known theory. » 11/03/11 7:00am 11/03/11 7:00am

What are your prospects for getting a faster-than-light drive?

The prospect a faster-than-light spacecraft is incredibly tempting. But is it practical? Do the laws of physics really allow us to travel to other systems in a human lifetime? In this week's "Ask a Physicist," we'll find out. » 9/15/11 11:00am 9/15/11 11:00am

Forget Warp Speed, Try One Of These Alternative FTL Ideas

In Star Wars and Star Trek, the main way to get around the galaxy is to use warp speed or flip on your hyperdrive, which is a bit like hitting the gas pedal as hard as you can so you'll get there a bit quicker. There's more science to it than that, involving subspace fields and hyperspace and all that jazz, but the… » 4/22/08 3:40pm 4/22/08 3:40pm

Controversial SciFi Realist Tells io9 Why Warp Drives Suck

Most science fiction movies make jumping to other star systems look as easy as stepping out for a bagel. But scientists think it'll never be that easy. So science fiction author Geoff Ryman (Air) invented a new school of writing called Mundane Science Fiction, which avoids faster-than-light travel, time travel or… » 12/14/07 11:30am 12/14/07 11:30am
