The title of the thread was also the title of either a Geocities or Angelfire page that linked to an academic journal that improved Van den Broeck's Micro-warp bubble by theorizing that if extra spacial dimensions did exist at the millimeter level instead of prohibiting the concept they could be used turning a warp drive into a hyperdrive. But I can't seem to find either the website or the academic journal hope someone can find what I'm looking for.
 
Here older Paper by Chris Van den Broeck

So it submerges the erstwhile starship in a 'sub space' pocket. Yes, I'm calling the inside of a metric pocket 'subspace'.

This is probably the related paper about the Broeck ”pocket” you were looking for:

The Analysis of Chris Van Den Broeck Applied to the Natario Warp Drive Spacetime Using the Original Alcubierre Shape Function to Generate the Broeck Spacetime Distortion:the Natario-Broeck Warp Drive

Okay.

What we need is a warp bubble with a large internal radius able to accommodate a ship inside while having a submicroscopic outer radius and a submicroscopic contact external surface in order to better avoid the collisions against the IM particles.

(IM = Interstellar Medium)

Right. Otherwise everything you ran into turns into a gamma-ray blast in the direction you were traveling FTL when you drop back to subluminal speeds.

So they make an absolutely tiny Alcubierre bubble, radius of 3x10^-15 meters. 3 millionths of a nanometer. Then, Broeck makes a 200m diameter/100m radius bottle inside the Alcubierre bubble with a neck reaching into the real universe to see where you're going?

The heat problem would be significant. The ship inside the bubble would not be able to radiate heat outside (since the exterior is too tiny) and would be forced to rely on heat sink to store the heat till the end of the journey.

It's an unfortunate misunderstanding due to the graphical representation.
It's actually three bubbles.
The usual Alcubierre warp bubble; then small compressed bubble to avoid IM inside the warp bubble and then the normal sized space bubble for the ship.

No, since the warp bubble remains unchanged.

As I understand it the lower energy requirement is due to stacking the manipulation effects. But, honestly, this is like piling on more problems on top of the problem of creating the war bubble in the first place.
 
On a theoretical level. Does the pocket of spacetime need to 'move'?

All that matters is the 'throat' that connects the pocket to the universe. The pocket exists off into hyperspace or subspace or whatever you want to call it.

I think the idea is to make the Alcubierre bubble as small as possible so that it contacts the smallest possible amount of interstellar materials.

And then the throat to the pocket is inside the Alcubierre bubble.

I think.

It depends on the point of view of the reference frame.
In this case the scaled bubble inside the warp bubble does not need to move but due to gradients it is disturbed a bit so there is some movement.

The warp bubble moves relative to the universe. And the bubbe around the ship only moves if the ship uses its thrusters.
Imagine space-time is like a fluid and is still-water (flat space-time). In any other state it is disturbed and flows.
 
As easy as piloting the Enola Gay

I wonder if anything can come of this
https://journals.aps.org/prl/pdf/10.1103/xd97-c6d7https://phys.org/news/2025-12-laser-quantum-nature-gravity-graviton.html
Now, Prof. Ralf Schützhold, theoretical physicist at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), is going one step further. He has conceived an experiment through which gravitational waves can not only be observed but even manipulated.

Published in the journal Physical Review Letters, the idea could also deliver new insights into the hitherto only conjectured quantum nature of gravity.

On magnets
https://phys.org/news/2025-12-archimedean-encode-chirality-magnetic-materials.html"Dirk and myself were initially inspired by the elegance of the Archimedean screw and began wondering whether we could build a magnonic analog, something that could 'pump' magnons (i.e., collective electron spin excitations) in a similarly directional way," Dr. Mingran Xu, first author of the paper, told Tech Xplore.

I want that spin-dizzy some kind of way.
