putting the wormhole inside a ship travelling at near C speeds is only an exercise of imagination to better visualize the travel in time problem, since you get such a huge difference in the measured clock time.ScottL wrote:I'm assuming ME applies to the traditional though of wormholes, from A to B, folded paper exercise.

I guess I pictured always as a punch through so to speak. The event horizon would be the vector into space and the distance would be related to the origin's power. I never thought of it as having to hold 2 mouths open to acocmplish.AcesHigh wrote:putting the wormhole inside a ship travelling at near C speeds is only an exercise of imagination to better visualize the travel in time problem, since you get such a huge difference in the measured clock time.ScottL wrote:I'm assuming ME applies to the traditional though of wormholes, from A to B, folded paper exercise.

but the effect will be the same (albeit the time difference will be much smaller) if one wormhole is orbiting the Earth (I am not sure wormholes can orbit something, whatever) and the other wormhole is near some massive gas giant. There are still small deformations in space time caused by nearby gravity from bodies as well as movement through space time.
THUS, the problem of travelling to the past still exists, although we would be talking of microseconds here.
sounds like a fun weapon.And there is also the question of writing the environmental impact statement. What would happen to external objects (space dust, rocks, other ships, asteroids, planets, ...) that happened to lie in the path of an Alcubierre ship and entered the region of distorted space-time at the leading edge of the warp, where space is rapidly being collapsed? The nuclei of any matter transiting that region would first experience enormous compressional forces, probably form a quark-gluon plasma reminiscent of the first microsecond of the Big Bang, and then explode in a flood of pi mesons and other fundamental particles when the compression forces were released, stealing energy from the warp field in the process.
A ship traveling in an Alcubierre space warp should be equipped with plenty of radiation shielding. Perhaps that is not a problem, since the equations for the metric and the energy density of the warp do not seem to depend on how much mass is placed in the flat-space region which is given an FTL velocity.
Actually it does. Wormholes connect disparate space-times, which means they're just as able to connect different times as they are different spaces.ScottL wrote:I'm assuming ME applies to the traditional though of wormholes, from A to B, folded paper exercise.

We don't know that one can't generate the second mouth when one generates the transit between. There's just too little understood about this to date but I think once Jim's book comes out in November we can expect the dawning of serious discussion of these things and perhaps we'll see some more concrete wormhole theory emerge as result.djolds1 wrote: Yes, transit is instantaneous once the wormhole mouths are on station. But getting them in position in the first place takes time.
Going by the paper Paul referenced yesterday:AcesHigh wrote:anyway, I suppose it wouldnt be healthy to travel with a warp drive inside a planetĀ“s atmosphere... it would rule out too the assumption aliens use craft that use warp inside the atmosphere (which would allow them the thousands of Gs maneuvers)
Instant RKKS. Terrifying. Mobile space-based city-ships may become necessary because planetary civilization is a suicide pact.AcesHigh wrote:sounds like a fun weapon.
Thorne wormholes are as I described. Unless I've overlooked something in either of Jim's wormhole papers, his concepts follow the Thorne wormhole guidelines. "Punch through" wormhole generators/ "stargates" would be game changers, but are not part of standard wormhole theory to the best of my knowledge, leaving warp drives as the only option for arbitrary-destination rapid FTL travel.GIThruster wrote:We don't know that one can't generate the second mouth when one generates the transit between.

I stand corrected.AcesHigh wrote:Djolds, I was not talking about relativistic weapons or acceleration inside the warp bubble, but to what happens to matter from the atmosphere (or from the planet itself) when it enters in contact with the borders of the warp bubble.
"The nuclei of any matter transiting that region would first experience enormous compressional forces, probably form a quark-gluon plasma reminiscent of the first microsecond of the Big Bang, and then explode in a flood of pi mesons and other fundamental particles when the compression forces were released"
at vacuum there would be little enough matter being compressed and then exploded as pi mesons and other fundamental particles. But inside an atmosphere? Or if the warp bubble touched the ground of a planet...
I suppose that in the area where the warp bubble is compressing space-time, matter may come close to neutron star levels in density and then its expanded again when it crosses the border...
I thought you guys were planning to do the "Q" thruster experiments first.paulmarch wrote:
And those warp bubble experiments commence here at the Eagleworks Lab as soon as we get our replacement laser delivered and installed. That should happen by end of next week if the vendor meets their current delivery schedule.
Best,
As it has turned out, we have bets as to which experiment will reach first light status. As of today we are still waiting on the replacement laser for the warp field experiment, but I'm also dealing with shorted coaxial RF power feed connectors for the Q-Thruster, and my other job at JSC, which is the development of nuclear electric power for space applications. That job consumed 4 hours of my day today, but either one of these advanced propulsion developments is going to need a portable high power supply to drive them...kurt9 wrote:I thought you guys were planning to do the "Q" thruster experiments first.paulmarch wrote:
