This has the large benefit of allowing the acceleration effects of the drive to be largely negated. Rather than coupling the bubbles to the hull solely by magnetics, the intense gravity gradient of the bubbles is also used to move the hull around.
Usually, S:5 bubble drive ships have many hundreds to several million drive bubbles around a fairly conventional deep space hull. Second, the combination of the large mass and small size in our universe combine to give the bubbles a small but very steep gravity gradient. First, the additional mass serves as a much larger fuel source, increasing the longevity of the drive bubbles. The bubbles become much larger internally, and far more mass can be included within them as they are created. Such sturdy materials as diamondoid, sapphiroid, adamant, silicon, most metals, and properly hardened devices or sophonts based on these materials are generally durable enough to withstand the removal of an S:5 Void Bubble, but some reports may be apocryphal. A Halo Ship of the Mutual Progress association, showing the massive gravitomagnetic coupling pods at the front of the shipĪt Singularity level 5 Void Bubbles are still mostly 'single use' technology, although they can be unmade without destroying most non-biological contents.
