Not entirely sure if this is the right section for this question.
Hypothetically, you can achieve FTL travel by bending spacetime around a spaceship ...
If such a device would be built ... would it be able to go past the event horizon of a black hole and then escape out of it? (I mean...
I'm sure you've heard of the warp/Alcubierre drive that would work by expanding space behind it and contracting it in front to achieve faster than light travel. I was thinking about this the other day and was wondering if this concept could be applied to time as well to allow time travel. Would...
Alcubierre Warp Drive With Rings Story Research
I'm writing a new section in my science fiction novel and need a little help with the science of it.
So, the general idea of the Alcubierre Warp Drive is that with 65 exajoules you can create a warp bubble by expanding spacetime behind you and...
If gravity waves are supposed to propagate at c, how could the theoretical warp drive wave propagate at greater than c values?
I have heard and red and understand that space itself can expand (and warp? ) faster than c and, in fact, that will happen in the future when space in between...
I have noticed that, in the plastic extruded from 3d printers, plastic fork that i put near the fire during bonfires, whenever plastic is heated they tend to warp(curve up) why is that the case?thank you
Alcubierre Warp Drive: Debate and Discussions (Force Fields; Dampners)
I would like to first of all apologize if this is not in the correct location or if this thread violates any of the forum's rules.
The purpose of this thread is to discuss, debate, and bounce ideas around regarding the...
I understand that in GR mass is considered a distorting of space-time.
If you had a teleporter which transmitted an object's energy perfectly as photons to be reconfigured at a perfect reciever at the destination location, whilst in transit as a (very high energy) light pulse, would the same...
This is a very blunt guess, but since light can warp space-time a bit better then gravity, and that light is a ripple in hyper space. Could it be possible for 14 powerful lasers that are guided by "mirrors" around the ship to form a circle powerful enough to reach warp speed? The idea of a big...
I've been trying to follow these experiments that NASA is doing to try and warp space-time on a microscopic scale. Obviously that won't have us traveling at FTL speeds yet, but it would be proof of concept. From what I read, they are using a laser, and some kind of special ceramic material (I...
Popular Science has been running an article about Sonny White, a prominent engineer at NASA's JSC.
White has been attempting to realize a warp drive as theorized by Miguel Alcubierre of UNAM in Mexico.

NASA could build a warp drive?!?
I just read in a article that NASA has revisited an older theory and found they can improve on it greatly. here is a link to the journal (i guess that is what it is called) of the scientist who is working in this...
Hey guys. Just wanting a bit of feedback on the beginnings of a short story. It's set in the Warhammer 40k universe and is kind of dark, so be warned. And since I'm terrible at choosing names I just used my own for one of the characters for now.

I know that mass warps spacetime and that's basically the force of gravity (warped spacetime), but why does mass warp spacetime? Is it because mass implies energy and energy warps spacetime? If so, then why does energy warp spacetime?
Could somebody please explain the following equation for me?
ds^2 = −c^2 dt^2 + [dx − vs (t)f(rs)dt]^2 + dy^2 + dz^2 where f(rs)=(tanh(σ(rs + R)) − tanh(σ(rs − R)))/(2tanh(σR).
I've wrestled with it for a while, but quite frankly do not get it. I'm only up through Calc II, but I'm more than...

This is just one article, but they're are plenty more to be found. There is one thing that confuses me though. Alcubierre's warp drive idea seemed to...
I was reading this article today: http://news.yahoo.com/warp-drive-may-more-feasible-thought-scientists-161301109.html
and in it it states this:
How did they come to the figure of 10*C? Is it a matter of energy input to speed output?
Not sure where to post this or if this can be solved, but I couldn't figure it out because math and physics are clearly not my strength :)
I am writing a book where one of the characters has the ability to speed her travel through time. Basically, she is in a type of warp bubble, for lack of...
If you were able to create a bubble that was separate from this universe space/time, would that bubble if standing still allow space/time to move around it thus making it appear as if you actually moved through space, even though space/time moved around you. Since we are moving thru space at 2.7...
I'm sure a lot of you have heard of the warp drive theory. I can't seem to find much on the bubble part, though. In theory, will the bubble be something you can actually see and touch?
If the warp drive is shut down either by its destruction or just plain turning it off, what happens? Does the vessel stop? Continue coasting forward? If so how would the time dilation factor at speeds several thousand times the speed of light?

Hello Everyone,
It has been awhile since I have been on the forums. I just finished my third year which was my transition from biology to physics. So far, I have completed first year courses on Mechanics and Electrodynamics as well as one course on introductory quantum mechanics. Now I am...
ok last dumb question for tonight i promise... i have read that you can theoretically warp space (on paper not in a lab). let's say we built a warp drive however... if you were traveling through warped space say on the enterprise and shined a flashlight off the front of the ship would it still...
I am interested in learning more about the Alcubierre warp drive. Although I've read every qualitative description imaginable plus Lillian Lieber's The Einstein Theory of Relativity, which gives a BRIEF introduction to the math behind GR, I am totally lost when it comes to the math. Although I...
Take as example a neutron star. Its mass warps the space(time) which the neutron star itself occupies (the space inside its perimeter). Does this effect make the neutron star smaller? If we could put a neutron star in unwarped space, would it occupy a bigger volume?
I mean, does it look...
I love Star trek and I was thinking, how to create a warp drive.
I have read a discusion about EM waves on this forum, there was written that they do not need any medium for propagation and : “In a simplified sense the oscillating E field sustains the oscillating B field which sustains the...
Space (outer space) itself is the absence of everything, or what's left after all the dust, various types of radiation, photons, neutrons, etc. etc. are removed. That is, space will still be there when all else is gone.
So exactlyhow does a large mass, like our sun, warp something (space)...

I wanted to ask that if a person returned home after a journey at the speed of light for a little while ; what will be the time at his home. I mean would all his relatives be dead by that time or would just a second have passed.
In 1994 physicist Miguel Alcubierre proposed a method in the Journal of Classical and Quantum Gravity for a means of traveling faster than light with the creation of a warp bubble. The front part of the bubble compresses the space in front of the ship, while the back end of the bubble expands...

According to General Relativity the stars and planets cause a warp in the fabric of space time, right? Now, if planets' orbits are governed by the warping of the fabric of space time, then how are the gas clouds in Nebulas affecting that fabric? Also how do galaxies affect that fabric? Do they...
I’m trying to think of an easier way to describe how space and time will warp with velocity. This is only an analogy and since I’m not a physicist or mathematician I don’t have the ability to compare the resulting equations to Einstein’s theory. I am not trying to disprove or refute anyone’s...

Any links/ organizations you know of? I'm already familiar with the now defunct "warp drive today" site, the axed NASA BPP project, and the Alcubierre/Van Broeck papers. There really should be an organization of some sort that gathers all the latest science into one place.
In this new paper, http://arxiv.org/abs/gr-qc/0406083 , Lobo & Visser apply linearized gravity to the famous warp drive solutions of Einstein's equations. They are able for the first time to consider an extended (not pointlike) spaceship of finite mass. They find, no surprise, that the warp...
