> Who's to say a quasar isn't just a lovely time clock for signals encoded in the noise

Apart from a) quasars are broad-spectrum, not narrow frequencies (at least I assume that is the case), and b) the power required is too large for a civilization to realistically be able to generate. Not to mention that all that power is overkill for intragalactic communication.

But it’s a good sci-fi idea!
