Yes, Stellar manipulation but I don't remember which level exactly. But that's a LOT of researching, building and maintaining.
It's interesting for me too, because I've never used such a component and don't know how it works. Will it destroy the ship itself?
I believe so because if you blow up a star - everything should be destroyed as well. This means other stars, planets, ships, asteroids, etc. And there probably a random nebulae should appear. Well, that's how I imagine it would work
Anybody with real experience in the field?
