science fiction – How can blood gas area journey?

My query is what’s inside blood that may gas/be utilized in hyper area journey?

+1 to Klyis’s reply, which was fairly near what I used to be going to say. But, as an alternative…

Hyperspatial geometry is tough, and biocomputers want gas

A reasonably sensible take that I’ve used worldbuilding as nicely is that this can be very tough to resolve the ten coupled nonlinear partial differential equations that govern the connection between matter and the geometry of spacetime — not as a result of that is cool technobabble, however as a result of it is true. The Einstein field equations are notoriously tough to resolve precisely even simply as soon as in extremely static and symmetric spacetimes, not to mention repeatedly for complicated ones.

Whatever FTL wormholes or stardrives or such that your alien race makes use of, they want computer systems highly effective sufficient to resolve the EFEs reside in an effort to safely navigate interstellar area. At first, they precomputed their routes over the course of years and hoped that nothing would mess them up, however after they found different organisms with complicated stable brains and such, they took that concept and bioengineered stem cells into dwelling computer systems, with larger cellulo-transistor densities than anything on this planet.

Only drawback is, computer systems generate warmth, and highly effective computer systems generate numerous warmth, and biocomputers want blood to outlive. So, to maintain their biocomputers alive, they both must cryogenically rapid-freeze them or provide them with nutrient-rich blood continuously, but it surely additionally boils off because the biocomputers churn away at doing the calculations essential to preserve FTL subspaces secure. It seems to be harder to synthesize an equal of blood than to simply harvest it from creatures suitable with the biocomputers, so after they encounter a civilization in want of FTL journey, they ask for a blood sacrifice (on this case, people), they take 5% as cost, after which dump the opposite 95% into the biocomputers to run them at most effectivity.

Not solely do they worth blood, however it’s functionally inconceivable to bridge interstellar area with out it.
