free space exploration and true worm holes

possibility to send fleets out of the lines of connection between systems.

I would like to study the "free space" with an actual ship. not just probes, it would be amazing if you could do it and there were secrets that probes couldnt find and there were no "special routes" to get to them, if you could move freely a ship in space towards one direction and till the end of turn you could change its direction. that would be awesome. 

Worm holes, that if your fleet approaches them they will be devoured by them and possibly 50% chance recover them in the other side of the map or random location.
