I didn't know that the Collectors' tech was based on dark energy, I just knew about the whole Haestrom thing. It likely will be involved somehow, then, but seeing as the Collectors were using it, it's Reaper tech. Reapers being able to accelerate and destroy stars does not bode well for the galaxy.
