Star Trek Warp Engine -
NASA's Scientists Attempt To Make Faster-Than-Light Travel Possible!

Follow us: - If our spaceships were equipped with a warp-drive engine, like in Star Trek then our astronauts could explore all corners of the Universe.

A group of researchers at the NASA's Johnson Space Center are convinced they develop technology that can turn faster-than-light into reality.

In order to achieve this, scientists would have to to break, or at least bend the rules of time and space famously laid out by Albert Einstein over 50-years ago.

Harold G. White, a physicist and advanced propulsion engineer at NASA and his colleagues have been trying to construct instruments, with the goal of using them to slightly warp the trajectory of a photon, changing the distance it travels in a certain area, and then observing the change with a device called an interferometer. Basically, the team is trying to determine whether faster-than-light travel - warp drive - might someday be possible.

"Space has been expanding since the Big Bang 13.7 billion years ago," said Dr. White, 43, who runs the research project.

"And we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would've went receding away from each other at very rapid speeds."

"Nature can do it," he said. "So the question is, can we do it?"

In our article, Alcubierre Warp Drive - A Doomsday Weapon we discussed whether such a warp drive should be regarded as a force of destruction or our passport to the Universe.

The Alcubierre warp drive is a theoretical tool that would allow for spacecraft to travel long distances in space rapidly, by deforming the space-time continuum in a bubble around the spaceship.

Miguel Alcubierre, a Mexican physicist, proposed this warp drive in 1994 as a way to travel globally faster than light, overcoming the limit on particles travelling at such speeds in Einstein's theory of special relativity.

"It sounds like it's straight from science fiction, and in a way it is, as the Alcubierre warp drive is a theoretical solution to the problem of travelling the huge distances in space in a reasonable amount of time.

Alcubierre's theory involved harnessing the expansion and contraction of space itself.

Under Dr. Alcubierre's hypothesis, a ship still couldn't exceed light speed in a local region of space. But a theoretical propulsion system he sketched out manipulated space-time by generating a so-called "warp bubble" that would expand space on one side of a spacecraft and contract it on another.

"In this way, the spaceship will be pushed away from the Earth and pulled towards a distant star by space-time itself," Dr. Alcubierre wrote.

Dr. White has likened it to stepping onto a moving walkway at an airport.

In New York Times' article Dr White explains that he believes "that advances he and others have made render warp speed less implausible. Among other things, he has redesigned the theoretical warp-traveling spacecraft - and in particular a ring around it that is key to its propulsion system - in a way that he believes will greatly reduce the energy requirements."

"For NASA, Dr. White's warp speed experiments represent a rounding error in its budget, with about $50,000 spent on equipment in an agency that spends nearly $18 billion annually. The agency is far more focused on more achievable projects - building the next generation Orion series spacecraft, working on the International Space Station and preparing for a planned future mission to capture an asteroid.

But it has made internal resources available for the project and freed up other engineers to assist Dr. White. It has also restored the pneumatic system in the laboratory Dr. White is using, to allow it to float. The lab was once used to test equipment for Apollo missions and has control panels underneath it that look like they belong in a fallout shelter that time forgot.

Steve Stich, the deputy director of engineering at the Johnson Space Center, said, "You always have to be looking towards the future." He held up his iPhone.

"Forty years ago, this was 'Star Trek,' Captain Kirk talking on a communicator whenever he wanted to," he said. "But today it exists because people made the battery technology that allows this device to exist, worked on the software technology, worked on the computational technology, the touch screen."

Theoretically, a warp drive could cut the travel time between stars from tens of thousands of years to weeks or months. But we should probably not book reservations anytime soon.

"My personal opinion is that the idea is crazy for now," said Edwin F. Taylor, a former editor of The American Journal of Physics and senior research scientist at M.I.T. "Check with me in a hundred years."

But Richard Obousy, a physicist who is president of Icarus Interstellar, a nonprofit group composed of volunteers collaborating on starship design, said "it is not airy-fairy, pie in the sky."

"We tend to overestimate what we can do on short time scales, but I think we massively underestimate what we can do on longer time scales," he said of the work of Dr. White, who is a friend and Icarus collaborator.

Dr. White likened his experiments to the early stages of the Manhattan Project, which were aimed at creating a very small nuclear reaction merely as proof that it could be done.

"They tried to go through and demonstrate a nuclear reactor and generate half a watt," he said. "That's not something you're going to market. Nobody's going to buy that. It's just making sure they understood the physics and science."

Neil deGrasse Tyson, the well-known astrophysicist at the American Museum of Natural History, said some leap beyond our current technology would be needed to make interstellar travel feasible.

"Routine travel among the stars is impossible without new discoveries regarding the fabric of space and time, or capability to manipulate it for our needs," he said, adding, "By my read, the idea of a functioning warp drive remains far-fetched, but the real take-away is that people are thinking about it - reminding us all that the urge to explore continues to run deep in our species."

Still, one of the most dubious is Dr. Alcubierre himself. He listed a number of concerns, starting with the vast amounts of exotic matter that would be needed.

"The warp drive on this ground alone is impossible," he said.

And he posed a more fundamental question: How would you turn it on?

"At speeds larger than the speed of light, the front of the warp bubble cannot be reached by any signal from within the ship," he said.

"This does not just mean we can't turn it off; it is much worse. It means we can't even turn it on in the first place."

Dr. White, who has never spoken to Dr. Alcubierre, said "I appreciate his thoughts. I don't know whether I agree with all of his observations, based on some work I've done."

"He and I could certainly debate for a very long time," he added."
