Starwings theory about why the Shivans do what they do (STWSDWTD). I'm not going to explain it over and over again, just do a search for it

Starwings theory why the Shivans blew up the Capella star (STWSBUCS):
1. Please remember that the mysterious subspace field was generated long before the supernowa weapon was actually engaged.
2. According to STWSDWTD the Shivans are at war with their creators. This race wad been called the Titans.
3. Titans had a unbreakable fortress from where they attacked the Shivans. Shivans needed to find a way to destroy it.
4. Shivans entered GTVA space after the Knossos had been reactivated.
5. Shivans find something in the Capella system, probably an unstable node.
6. Shivans send their fleet of Sathanas ships to Capella.
7. Sathanas engage their subspace drives to open an artificial subspace corridor to the Titan base. Hence the mysterious subspace field.
8. Shivans blow up Capella. Parts of the plasma are sucked into the corridor.
9. Some Sathanas class ships also enter the corridor to stabilize it until the plasma reaches the other side. Others remain in Capella to keep the corridor entrance open.
10. Plasma strikes the Titan base, boom. Plasma strikes the Shivans in Capella, boom.
Plasma strikes everything else in Capella, boom.
