Where did you get that from? Based on what's stated in the databanks and on what the devs said so far, there is a very good chance, that the Terror Stars won't be in the base game. So how are we supposed to destroy stars?

In one of the dev streams Paul offhandedly mentioned that black holes are places were "you just can't go there, you have to go around them." So i'm assuming they are just unpassable terrain, but hoping for a bit more then just that.

I'd need to re-watch the dev streams, but I think I recall something like that. In all likelihood, they were referring to the Terror Star, because I doubt, that the devs will add another mechanic to destroy star systems.

The means to do that in both games was the Terror Star. However, it's been made pretty clear in the databanks, that the plans to create TS have been destroyed by the Thalan. This makes it unlikely that we'll see the TS in the base game. When I asked about it, Frogboy reinforced my suspicion (though it's still possible, that I misunderstood what he meant).
