  > any stable solar system capable of sustaining life will emit a steady heartbeat, just like a living being What do you mean? What would be the source of the regular wave-like signal, and why only systems with life have one? Do you mean that actual hearts beating create gravitational waves?

Solar systems that harbor life (our own, for example) are not the only stable solar systems. A stable solar system is however required to be the genesis grounds of life as we understand it, otherwise the building blocks of such potential life would be swallowed in the chaos and heat.

      How does stability lead to a wave? We can see wobble in stars to know they are getting tugged by planets. Are you expecting similar with gravity? I'm not a physicist nor astronomer. I wouldn't expect any gravity waves as I'd expect the star system to have a center of mass that stays in roughly the same space.

  In the movie interstellar were they using gravitational communication to write the book? Can someone enlighten me?

Remember that that 8 solar mass gravity wave source is potentially 100’s millions of light years away. A sci-fi author could conjure up a ‘portable box’ containing a couple of orbiting micro-scopic black holes in a box to generate gravity wave signals someone somewhere in the solar system could pick up with a portable LIGO device. Consider this comment a patent on the idea :-)
