What exactly are "thought scientists"?

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.
Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially brining the idea back from the realm of science fiction into science.
"There is hope," Harold "Sonny" White of NASA's Johnson Space Center said here Friday (Sept. 14) at the 100 Year Starship Symposium, a meeting to discuss the challenges of interstellar spaceflight.
Warping space-time
An Alcubierre warp drive would involve a football-shape spacecraft attached to a large ring encircling it. This ring, potentially made of exotic matter, would cause space-time to warp around the starship, creating a region of contracted space in front of it and expanded space behind.

Meanwhile, the starship itself would stay inside a bubble of flat space-time that wasn't being warped at all.
"Everything within space is restricted by the speed of light," explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. "But the really cool thing is space-time, the fabric of space, is not limited by the speed of light."
With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.
The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.
Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more, White found.
"The findings I presented today change it from impractical to plausible and worth further investigation," White told SPACE.com. "The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at in the lab."
Laboratory tests
White and his colleagues have begun experimenting with a mini version of the warp drive in their laboratory.
They set up what they call the White-Juday Warp Field Interferometer at the Johnson Space Center, essentially creating a laser interferometer that instigates micro versions of space-time warps.
"We're trying to see if we can generate a very tiny instance of this in a tabletop experiment, to try to perturb space-time by one part in 10 million," White said.
He called the project a "humble experiment" compared to what would be needed for a real warp drive, but said it represents a promising first step.
And other scientists stressed that even outlandish-sounding ideas, such as the warp drive, need to be considered if humanity is serious about traveling to other stars.
"If we're ever going to become a true spacefaring civilization, we're going to have to think outside the box a little bit, were going to have to be a little bit audacious," Obousy said.

Maybe there should be a comma after "thought"?
sigm me up to be on the first flight. I'm tired of the idiots on this planet and would gladly take the chance of exploding in the darkest area of space rather than having to deal with religious idiots who believe a man in the sky watches over them.
At the very least, I would be contributing to the advancement of the human race instead of trying to keep it in the Dark Ages like religion does.
Pseudo-science. When we can warp space/time, let me know.

once, someone said the earth had an edge and that the universe revolved around us....
Are you going to be that same person?
While infantesmal, time travel is already a reality with space flight. look it up.
If you come back and say you understand quantum physics, you obviously dont understand quantum physics.(in case you dont know, thats the joke/reality/basics of quantum physics).

Flat Earthers were wrong ergo we can fly 10x the speed of light because a Mexican scientist said so.http://www.zdnet.com/quantum-telepor...rd-7000003883/

I side with Hawking on this. Where are the tourists from the future?
was doomed to fail imho. the ers are stupid to try to make a football-shaped spacecraft when most existing spacecrafts that have been used by aliens are mostly round shaped.http://www.zdnet.com/quantum-telepor...rd-7000003883/

and i don't believe there's any possibility of making a time machine that enables you to tour the world of any time in the past or future. according to the principles of general relativity, you can make a machine in which the gravity is extremely huge, hence the time there passes very slowly. say if you put a human in it (provided he can stand the extreme conditions) and ask him to stay there for 24 hours, although the time he goes through IN there is 24 hours, it's just 24 hours for himself and the world outside has experienced a much longer time during the same process. that's the only feasible type of time machine imho
therefore you can send someone to the future by this means, but it ain't gonna work the other way around. also it's a philosophical contradiction to send someone to the past, as DMC quoted "where are the tourists from the future?"
idiots who believe we can travel back to the past better hope it doesn't happen because if it does, i'd travel to the past and tell their moms to abort pregnancies instead of giving birth to these heads tbh
You would have to beat us to doing the same to you.
they will appear when the first warp drive goes online
Right about the time monkeys fly out of my ass.
Shut up got, you probably didn't graduate HS and have no idea about any science more complex than sucking a boiled egg down a milk bottle.
Mexican scientist is an oxymoron anyhow. So he can get us to the past but he cannot feed his family and so they died of dehydration somewhere along the border.
DMC, stretching his foreskin over hemann's head and making him wear it as a hat.
warping...thats like taking a
seriously to open a warp drive, dont u need a warp gate, then u need to transfer the materials to that distance and build one....
they think opening a warp gate is like opening a black hole anywhere they like
All you need to do is break the link between mass and what ever force is in space that makes mass increase as the mass moves.
wind, but wind must come from somwhere to make it to move...
then u have to solve the mass
There is something in space that we are unaware of. What we perceive as empty space, isn't empty. It keeps mass from being able to break the speed of light. All we have to do is figure out how to manipulate it. Better yet, also figure out what it is.
Hey professor WC Google why not first find proof man evolved from an ape so I can go to bed already?
yeah that's honestly something to worry about for me tbh, since im only 11yrs old and so you don't need to travel that long like 30yrs or something to accomplish the mission. i said it because im 100% confident that it won't happen, EVER
there ain't in the space im telling ya, light-exceeding speed isn't at all an impossible but the fact is even if it does exist, you can't see it simply because it travels faster than light. you eyesight can't catch it so it appears as a blackhole, but you know something exists there inferring from its interactions with other planets nearby
I don't believe that as a fact. Only a hypothesis. I believe it is equally possible that an interpretation of an old Sumerian scroll is correct, that mankind on earth was altered by the god's to our present form about 60,000 years ago.
I an not dumb enough to claim I know such past events as fact like you do. You and Cosmored seem to be in your own world with your solid knowledge of fact.
psssssst! I was posting from the Science text books.
