Questions tagged [warp-drives]
warp drives are generic conceptual space travel mechanisms that try to work around physical limits in the speed of propagation of light imposed by special relativity. Usually they resort to speculative science (exotic matter), or phenomena that are not yet well understood or is hard to make validation experiments (non-eternal rotating black holes)

Is this solution for interstellar travel viable?
I have in mind a way to enable FTL travel. Is this way viable?
In the paper:
"Weighing the vacuum with the Archimedes experiment"
we can see the dependency of the gravitational repulsion ...

Frame dragging Warp drive [closed]
Is it possible to use frame dragging to make a warp drive?
For example: a space ship with "frame dragging generators" that constructively interfere between them to let space be dragged in ...

Dark energy as negative matter for Alcubierre drive
Can dark energy be used for the Alcubierre drive as a substitute for negative mass? After all, to make the Alcubierre drive work, it is necessary to expand the universe behind it, and that is what ...

The Explosive Force of the Braking Alcubierre Drive - What would this look like? [closed]
The Alcubierre Drive and faster than light travel more generally may be locked away in the realm of fiction forever. That might be depressing to some people but I think their impossibility is really ...

Alcubierre drive: what is the nature of exotic matter? [closed]
In connection with Alcubierre drive we often hear about necessity of an exotic matter in order to produce a negative energy density. I suspect that such matter has no place in standard particle model.

What would a Natario Warp Drive look like, outside & inside the warp bubble?
Within a Natario Warp Metric, all mass in front of the ship is pushed outwards by it's negative energy density, this means no light would interact with the front of the ship at all. And since the ...

In regards to the hypothetical Alcubierre Drive (hear me out), are energy costs consumed immediately, or during transit?
I am aware the Alcubierre Drive is highly hypothetical and likely cannot exist. However, there are significant quantities of research material into Warp Drives of many types, and presumably the answer ...

Approach for calculating Alcubierre energy function?
NOTE: I know that the Alcubierre drive is on shaky ground and I'm not asking about its practicality or physical feasibility. I'm also not looking for answers like, "It's sci-fi so you can just make it ...

What would be the energy requirements for non FTL warp drive? [closed]
I have a question about Alcubierre Drive, or other Warp Drive concepts.
I have read a lot about FTL warp drive and the massive energy requirements to perform a jump, varying from bigger than the ...

Since gravitational waves travel at the speed of light how are Alcubierre warp drives possible?
There are clearly some very large technical challenges to overcome before actually making one but most writers seem to think Alcubierre warp drives are possible in principle.
They work by propagating ...

How would an Alcubierre warp bubble be affected by external gravitational fields (e.g. black holes)?
Consider a spaceship inside an Alcubierre warp bubble traveling in a straight trajectory. As it travels, it passes near a black hole (for the sake of argument, we'll say it's near the event horizon of ...

Computing Riemann tensor components for Alcubierre metric
I am currently trying to compute the Riemann tensor components for the Alcubierre metric, and already, on the computation of the first component, I'm running into some issues.
The trouble component in ...

Alcubierre metric without geometrized units
In the beginning of Alcubierre's paper, he defines his metric with the use of geometrized units ($G = c = 1$). While it makes the math simpler, it seems to hide the physical numbers away, leaving me ...
