Cramer wormholes

[Tom Mazanec]

Is there any place in OAUP for these? They are featured in Cramer's recent novel Fermi's Question. If not, why not?

There were experiments in the early OA timeline with self-propelled, miniature wormholes; unfortunately they were not stable, and evaporated after a few metres.

To carry a wormhole a long distance in OA you need an external stabilisation framework, which is part of the gear carried by a wormhole linelayer.

Agreed with all this. Also, Cramer's wormholes are a different type than those used in OA. In OA - which is based on some RL theories relatively more recent than those the linked article is based on - there is a vast 'landscape' of possible WHs (IIRC the theoretical number is something like a 1 followed by 500 zeroes or is it 200 zeroes? Anyway) each with different properties and limitations. Most are not useful to Terragens due to being too unstable to use or having internal environments that disrupt any matter/energy that try to pass through them or massing so much as to be impractical to create. Or otherwise not being useful. For OA purposes, we say that the archai have 'discovered' a few possible wormholes that are both stable, traversable, and have mass requirements that are practical. Presumably, research in other 'useful' types is ongoing (and there may be other types the archai use which are some definition of 'useful' to them but which aren't of a sort where modos ever encounter them).

The wormholes Cramer describes are of an earlier generation of how WHs were conceived - basically they are stable at a much smaller size and mass. To some degree, the idea for them is 'a WH is a WH is a WH', at least above something like the Planck scale or the like. Ultimately, in RL they might turn out to exist - or might not. Much the same might be said for OA wormholes. We just don't know enough about space-time engineering at this point.

Hope this helps,

This paper is very interesting; it suggests that primordial wormholes could have spontaneously acquired negative energy, and persist to the modern era. This is one possible basis for the Fargate wormhole; a primordial wormhole (which could have originated via natural causes, so the Alpha Civilisation explanation is redundant - that doesn't mean it is necessarily wrong).
