New calculations of the energy required to warp spacetime suggest the Star Trek propulsion favorite could be tested.
A warp drive to achieve faster-than-light travel — a concept popularized in television’s Star Trek — may not be as unrealistic as once thought, scientists say.
A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy.

The U.S. Air Force’s robotic X-37B space plane finally returned to Earth Saturday (June 16), wrapping up a mysterious mission that lasted more than year in orbit.
The unmanned X-37B spacecraft, also known as Orbital Test Vehicle-2 (OTV-2), glided back to Earth on autopilot, touching down at California’s Vandenberg Air Force Base at 5:48 a.m. PDT this morning. The landing brought to an end the X-37B program’s second-ever spaceflight, a mission that lasted more than 15 months with objectives that remain shrouded in secrecy.

Scientists at Cambridge University prove that in this video, using Lego robots to create artificial bones. Making the bone structures is time-consuming and extremely repetitive, making it a great job for robots. It’s a task that could be done by expensive, specialized bots, but as we see here, robotics doesn’t always have to be so complicated. “The importance in science is the creativity in going forward,” Cambridge lecturer Michelle Oyen says in the video. “It’s not exactly what tools you use to get there.”
