Miguel Alcubierre came up with the idea of expanding the space behind a starship and contracting it in front of it. The starship would rest in a "warp bubble" between the two spacetime distortions. The result would be a wave in spacetime along which the starship would surf... There would be no limit to the velocity that a starship could attain. It could travel faster than the speed of light because the starship would, strictly speaking, be stationary in the space of its warp bubble. Also, the starship and its crew would be weightless and would therefore not be crushed by the enormous G-forces of acceleration and deceleration... What's more, the passage of time inside the warp bubble would be the same as that outside it. The crew would not suffer from Einstein's "time dilation" effect where time passes at different rates for people travelling at different speeds... Alcubierre's idea was a good one, but his work seemed to suggest that building a warp bubble would be impossible in practice. More energy than the entire universe could supply would be needed to create the spacetime distortions. However, Dr Van Den Broeck's analysis suggests a far lower amount of energy is required, reduced by a factor of one followed by 62 zeros... As Dr Van Den Broeck says in his forthcoming paper in General Relativity and Quantum Cosmology: "This does not mean that the proposal is realistic." ...But it just might be. Dr Van Den Broeck concludes his analysis by saying, "The first warp drive is still a long way off but maybe it has now become slightly less improbable."

As Dr Van Den Broeck says in his forthcoming paper in General Relativity and Quantum Cosmology: "This does not mean that the proposal is realistic."
So if realisticality is not required, why not use the switch method to travel space. Simply switch reality on and off. While off, leave your body, take off to wherever. When yo get there, turn the switch back on and pull your body to you.
parsy, the inventor of the switch method.
Can I just make stuff up as I go along, like this guy does?
AWK! They have the exclusive franchise?
eh???
Once we have antigravity (i.e. gravity control technology), we will be able to bend spactime to order. The creation of wormholes will follow.
And once we have wormholes, we won't need spaceships of any kind. Instead, we'll create a pair of nuclear-particle-scale linked wormhole mouths, A and B; then park A in Earth orbit, and use a particle accelerator to shoot B to the target star at relativistic velocity. (The wormhole diameter can be very small, since the diameter of the wormhole link need only be wide enough to allow a low-res communications laser beam to pass through the link.) Due to relativistic time dilation, only a few days will pass from B's point of view until B enters the target star system. Since clocks on both ends of a wormhole must always agree, those watching the view through A will see the target star appear from the point of view of B only a few days after launch. At that point we "spin up" the wormhole, opening both A and B mouths to a size large enough to pass a deceleration framework and engine through. The decel rig capures B, fires its engine, and decelerates B until it enters orbit around the destination planet. We then spin the wormhole up until it is big enough to pass loads of any desired size.
And once this is done, we have no more need for spaceships. With wormholes, all travel is local travel; therefore, instead of a ship, we travel between the stars by train.
The 16:15 Tau Ceti Overnight Express leaves Earth Station, traveling up the Space Railway ("space elevator") link. Once above the atmosphere, as dinner isserved in the dining car, the train accelerates to its cruise speed of about 8,500 miles per hour en route to Wormhole Junction over Earth. Traveling at full express speed, the trip to the Junction (and A mouth) takes about six hours. As the Pullman passengers settle into their sleepers for the night, the Express passes through the Junction, entering the A Mouth -- and emerging instantaneously from B Mouth in orbit around Tau Ceti's fourth planet! The train then begins slowing down, putting energy back into its magnetic track as it glides down the Space Railway link to the destination planet's surface. Six hours later, as the passengers are finishing breakfast, the Special pulls in to Nova Terra Station, having traveled about 100,000 miles from the point of view of a person aboard the train, and 11.6 light years through "real" space -- all by rail.
We'll settle the New Frontier the same way we settled the old one -- by rail. Now that's an American future!
oh... static repulsorlift. kewl.
You would feel no intertia/G-forces if your reference frame moved but you stayed at rest relative to it.
Never, EVER, stand on the flux capacitor!
Hey, watch it!
I resemble that remark.
Thanks for the ping.
First they've got to find or make dilithium crystals.
As soon as I saw the headline I thought of Miguel Alcubierre's paper on the warp bubble.
Interesting.

Beam me up, cheif!!!
I want a vacation on Bajor...
In what field, dipshitology?
There's so much wrong in this anthology of fiction that it's hard to pick any one statement, but my favorite piece of dreck is:
This doesn't need saying, but weightlessness is the consequence of "G-forces" being zero. So our estimable author/expert asserts what... that the zero accelation condition experienced by the imaginary crew is also enormous.
Enormously nonexistent?
Infinitely infinitesimal?
What utterly an irrational psuedo-intellect.
Don't hold back! Tell us how you really feel! ;')
