I do. 100,000 minerals for the answer. I can also loan you the relevant vessels, since you can pretty much bet I *always* research Stellar Manipulation.

You should download the SEIV Modder to easily see the prerequisites. There are quite a few of them, and they ended up taking me a good 100 turns of research to get, so I hope you are patient.

The prerequisites include Quantum Theory (Mathematics 3 is the main prerequisite), and Quantum Physics II, plus Universe Manipulation III, Warp Physics I, and a bit of Gravitational Technology.


Think of the cultural facilities not as facilities, but abilities. They have two main abilities:
- Resource production: in that aspect, they are just mineral facilities/rads... and they have their own production. Let me repeat that: cultural facilities have a production of their own.
- Planetary system increase: only the best value for each resource applies here, and usually the better the facility, the higher it is. Note that Agrarian facilities increase organics far more than anything else.

So, if you have a Minor City and a Cultural Centre, the City will still produce its resources, but the Cultural Centre will be the "ruling" facility for resource increase abilities. Because the City produces something, it will still increase your resource production, and it will benefit from the Cultural Centre huge planetary resource increase (X14 for minerals, if memory serves).
