Are there any Alcubierre Style metrics for sub-luminal speed warp drives?
In most literature I have found, research into the Alcubierre Metric, and Warp Drives seems to be highly focused on the plausibility of superluminal travel.
Today I was thinking to myself that maybe ...

Why does the Alcubierre drive need a negative energy ring specifically?
Now, maybe this is a result of my poor understanding of spacetime, but a theoretical warp bubble contracts space in front, and expands it in the back. Positive energy always contracts, so I get the ...

How was this warp bubble generated?
The Debrief just reported that DARPA just "accidentally" created the world's first warp bubble. The actual paper is available here.
My layman understanding is that warp drives were so far ...

"Swimming" in flat spacetime
Is it possible for a machine with a velocity of zero to translate its position in a perfectly flat region of spacetime? This is possible in curved spacetime https://groups.csail.mit.edu/mac/users/...

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 ...

Warping Space Time By Focusing on Getting Smaller Rather Than More Energy?
So all energy/mater warps space-time, right? However, whenever we talk about the human manipulation of space-time it is a far-off goal requiring nothing short of tremendous amounts of energy and ...

How can the Alcubierre drive itself move faster than light?
Assume that we have constructed an Alcubierre drive (we somehow managed to overcome all the difficulties). Now we want to want to move an object from galaxy A to galaxy B. We place it in the ...

Does localized space contraction occur?
There's the general space expansion due to dark energy and it acts in areas that aren't gravitationally bound. There's gravitational distortion of space around massive bodies, which also adds space. ...

Can Alcubierre Space Drive function in space time within event horizon of a Black Hole?
Alcubierre Drive compresses space in front and propagates as such but in a singularity where space is untraversable is propagation possible? If so can you prove it?

Can spacetime warp at a rate faster than light?
If you could decrease the distance between here and the nearest star by, say, four light years, wouldn't it take four years for that distance to disappear? For this reason, wouldn't so called "warp ...

Function to model deformed spacetime in 2D visualization of an Alcubierre drive
In the Wikipedia article on Alcubierre drive there is a top image. It is 2D visualization of an Alcubierre drive, showing the opposing regions of expanding and contracting space-time that displace the ...

Since Alcubierre drive moves a flat region of space, does it mean that space acts lika a liquid? [closed]
The Alcubierre drive would move a patch of flat space through space and, leaving exotic matter aside, is mathematically correct. Does that means that space-time is not a "solid" lattice i.e. not ...

Looking out from the inside of an Alcubierre bubble
Disregarding the difficulties in achieving a warp "bubble" as per Alcubierre's theoretical warp drive, as far as I understand it the geometry of the spacetime that arises is mathematically sound. ...

"Warp-drive" thought experiment
Why wouldn't this "warp-drive" work? Assuming we can build a flywheel that can survive near light speed and have an onboard power storage or beamed energy that can spin it up to that speed and back ...

Warp Drive conundrum - Speculative science question [closed]
Let me begin by stating that this question about Warp Engines/Drives, which i understand is a speculative, also I am not a Professional scientist or someone with a degree in physics. The question will ...
