Hyperspace Drive

I've always hated hyperspace travel. The swirl of color outside the viewports just makes me sick, but locking the shutters just makes me nervous. I swear I can hear something knocking on the metal when we do, but everyone tells me they don't hear anything, the pricks.

Through a complicated set of mathematical slates, a properly installed and operating Hyperspace Drive can access the Nösphere , and use it to make faster-than-light travel possible through bending those rules of nature we're so fond of.

By lightly submerging a object in the Nösphere, so lightly that without the energy expenditure of the Hyperdrive keeping it there it would simply fall back into realspace, it is possible to bypass the usual physical limitations of faster than light travel. Time no longer stretches due to the mass of the object being accelerated, but it should be mentioned that Hyperspace travel can be... unpredictable.

It is far more like sailing the waves of Earth than many would like to admit, with fluctuations and instabilities making it easier or harder to maintain the conditions that are conducive to speedy travel. Even when the Nösphere is calm, it is not a stable place, and as such travel by Hyperspace can vary in length. Most of the time, long distance travel is just ends up a few more days than normal, or in rarer cases a few days less. In more extreme cases, a ship can vanish for a months or longer without a trace.

Pair that with the unpredictable time dilation within the Nösphere, and the now missing crew might not even know that they have over or undershot their target location and date until they reach their destined port and look at a chronometer.
