Captain, you postulated 'clumps' of active dark matter interacting with our core generator, but our gravitic sensors detect only the static background of dark matter. It's the same static background we've observed for the last 20,000 of your years, in fact.
Put your pistol away, and I'll show you a real-time display.
Looks clumpy to me .
Oh, hey. That's new.
Oh, hey, we're all going to die.
