Look, I'm the Emperor and I say if they are going to discover a new ship hull, laser or nanobots to massage my foot. And scientists are going to deliever. I'm not intertesting in their excuses "like if they see some wormhole or whatever", I they can't deliever they will be reassigned to scrubbing nuclear reactors (there are billions loyal citizens in my domain eager to take their place).
Discovering a wormhole
Scientists are on *my* payroll, not on some wormhole/alien artifact payroll and they are going to do what *I* say. It can't work any other way, absolutely.
On map discoveries can be a nice addition, but the core research must be player driven. The choice is player's, we can't take it away from the player. Deciding what to research is a strategic decision, it must be in player's hands.
