This is the most fascinating idea I've heard in months! And very refreshing to hear you share my sentiments on the SCH ('Sans Ceiling Hypothesis'). As I've often said, if we can develop rigorous theories on FTL warp bubbles, traversible wormholes and black holes with just a tiny and poorly configured 3lb. brain, imagine what we could do with jupiter brains!
