Warp Drive remained in the world of fiction until 1994 when Mexican Mathematician Miguel Alcubierre presented a mathematical model under which a human-piloted craft could theoretically exceed the speed of light. A decade passed, but quietly in the background, NASA brought in scientist Dr. Harold G. “Sonny” White in the mid-2000s to continue developing the Warp Drive. White made refinements to the original model, and in 2003 and 2011, significant leaps were made in Warp Drive theory, seemingly making the impossible a little more possible. Even more revisions have been, and today, the leading model for faster-than-light travel is dubbed...

After appearing for decades in science fiction, then moving into an actual theory, a new patent for an updated warp drive was published last year to no fanfare. Like many other false starts in cutting-edge research, the patent may represent the next step in the expanding theory, or it could mean the practical, real-world design of a functioning warp drive is on the horizon. BACKGROUND: HOW TO BEND SPACE-TIME WITH A WARP DRIVE After first publishing his groundbreaking 1994 warp drive concept in the journal Classical and Quantum Gravity, Mexican Mathematician and Physicist Miguel Alcubierre received significant positive and negative...

HomeScience NASA’s Eagle Works: The Manhattan project of space travel. Karim Immanuel Chemlal A working microwave thruster would radically cut the cost of satellites and space stations and extend their working life, drive a plethora of suddenly affordable deep-space missions, and take astronauts to Mars in days to weeks rather than months. In 2011 the NASA engineering directorate created the Advanced propulsion team unofficially known as the “Eagleworks”. This rock star team of scientists and engineers are headed by Harold ‘Sonny’ White, engineer and applied physicist of NASA’s propulsion team at the Johnson space centre. The goal of the Eagle...

The roots of the propulsion system tested by the NASA team trace back to a British researcher named Roger Shawyer, who claims that his "EmDrive" generates thrust by rocketing microwaves around in a chamber. There is no need for propellant, as solar power can be used to produce the microwaves. Shawyer says that his company, Satellite Propulsion Research Ltd., has successfully tested experimental versions of the thruster. But many scientists have dismissed or downplayed such claims, saying the propulsion system violates the law of conservation of momentum, Wired UK reported. In 2012, however, a team of Chinese researchers built their...

Until yesterday, every physicist was laughing at this engine and its inventor, Roger Shawyer. It's called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can't explain why. Shawyer's engine is extremely light and simple. It provides a thrust by "bouncing microwaves around in a closed container." The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be...

Let me geek out on you (I love science) and explain to you the science (I love science) and why this had previously been confined to the pages of science fiction (I am a nerd; and oh Dear Sweet Bunsen-Burner Lighting Lord, do I love science). So it's a pretty firmly established principle that every act causes, and requires, an equal and opposite reaction. If I understand this right (did I mention I love science?), this means that any space vessel will have to carry with it an enormous amount of reaction mass. You can't -- we think, or thought...

“Star Trek” introduced the world outside of rocket science circles to the concept of warp drive – the propulsion system that allowed the starship Enterprise to travel faster than the speed of light. Warp speed is the holy grail that would let us explore the universe safely surrounded and protected by a space-distorting warp field. After watching the SpaceX rocket recently just try to land on a platform, you’d think this ability is years if not decades away. Yet the buzz on space websites is that NASA may have accidentally discovered a way to create a warp field. Wait, what?...
