How do plasma weapons overcome the bloom problem? Tech from the established anti gravity.
Is singularity weaponry vyable? Yes, but we needed to design an inhibitor for it.
Won't the aliens just call another fleet once we destroy this one? Yes. Our plan involves creating a warp-inhibitor to prevent future invasions.
The premise might be a tale as old as time; but if Goldhawk is telling it, it's a tale I would like to hear again.
(Edit* Though maybe we get to space this time? I can still dream.)
