Warp drive looks more promising than ever in recent NASA studies

The first steps towards interstellar travel have been taken, but the stars are very far away. Voyager 1 is about 17 light-hours distant from Earth and is traveling with a velocity of 0.006 percent of light speed, meaning it will take about 17,000 years to travel one light-year. Fortunately, the elusive "warp drive" now appears to be evolving past difficulties with new theoretical advances and a NASA test rig under development to measure artificially generated warping of space-time.

The warp drive broke away from being a wholly fictional concept in 1994, when physicist Miguel Alcubierre suggested that faster-than-light (FTL) travel was possible if you remained still on a flat piece of spacetime inside a warp bubble that was made to move at superluminal velocity. Rather like a magic carpet. The main idea here is that, although no material objects can travel faster than light, there is no known upper speed to the ability of spacetime itself to expand and contract. The only real hint we have is that the minimum velocity of spacetime expansion during the period of cosmological inflation was about 30 million billion times the speed of light...

Ah yes, but the emergency requires the evacuation of the entire Earth’s population of 5 billion people and the newborn. At the rate of your teleporter’s 2,200 people per hour, you’ll require more than 311 years to evacuate this 6 billion plus population or 311 of these teleporters or more for one year. This assumes of course the TSA screening and union work stoppages are not included in the estimates....

Can’t we just evacuate the conservatives?

Even if you limit the evacuees to 56 million U.S. conservatives, that only gets you down to 3 years transport time. If the threat is an ELE (Extinction Level Event) type asteroid coming from outside the Solar ecliptic from interstellar space, the detection and warning could be as little as months, days, days, or less.

Without the instantaneous teleporter you can see how impossible the situation can be.

As long as I go tenth.... because they gotta work out the kinks... I’ll be okay with it.

Project Deadelus was proposed to use fusion “bombs” instead of real fission bombs like the Project Orion proposal: http://www.daviddarling.info/encyclopedia/D/Daedalus.html

Nuclear-pulse engines would produce the plasma to propel the ship..

Deadelus needed to be large (54,000 tons) since its mission was to go to Barnard's Star.

Vasimr (Variable Specific Impulse Magnetoplasma Rocket) engines are another kettle of fish entirely: http://www.spaceflightnow.com/news/n1006/01vasimr/

Vasimr engines produce plasma via argon gas, electricity, super-conducting magnets, and a nuclear powered generator.

Vasimr engines are small and are at development stage 6, with stage 7 flight test in the next few years.

A 39 day trip to Mars would require a ship similar in size to a 747 jumbo.

Ad Astra Rocket is the main developer with NASA:

Re: There would be no G-forces inside of the bubble

Exactly!!

who makes the bend in the paper ?

Gravity. It bends space-time like a bowling ball on a big sheet of rubber. How do you generate the gravity? Hellifino.

Interstellar Highway Patrol Officer: Do you know why I stopped you?

"Here officer, hold my beer, and watch this"...then zoom away in your modified space vehicle at 30 billion times the speed of light...muahahahahaha!
