[Space] [Spaceships] : Mapping Hyperspace onto Truespace . . .

[vicky_molokh]

Greetings, all!

For a Hyperspace whose distances are proportional to Truespace distances (i.e. if Truespace distance between Sol-Antares and Sol-Sirius correspond as A:B, then Hyperspace travel time at a given speed between Sol-Antares and Sol-Sirius also corresponds as A:B, and this is true for any three solar systems), under the assumption that problems with causality/relativity are either handwaved or carefully fixed, there appears to be a problem that I do not know how to solve.

For a modest HS travel speed of 1ly/week (roughly 10M mps), even if we assume that ships can attain truespace speeds of 1K mps, this means that sizes of HS and TS correspond as 1:10K. For a fast hyperspace of 1pc/day (200M mps), and same TS speed, that jumps up to 1:200K.

This means that an exit sphere (a sphere that instantly 'falls' from HS to TS, along with its contents) of a 100-meter-long ship (a reasonable mid-sized ship of space op(e)rah sort), the TS volume corresponding equals a whopping 1000km, or an even bigger 20,000km if we want travel speeds of roughly 1pc/day (which is one ten-thousandth of an au).

I suspect the requirement to have such large exit spheres (and the similar problem with entry spheres) will result in the solar systems feeling overcrowded. However, not requiring anything like that might result in nasty collisions (and is likely to be weaponized in a MAD sort of way).

Anyone got ideas how such mapping is best worked out?

* == this likely means that HS curvature is proportional to Truespace curvature, right?
