&gt; Would it be possible to listen for information transmitted via gravitational waves? Would there be any benefit over radio?<p>Well, <i>if</i> you observe a meaningful, non-natural gravity wave signal, you <i>know</i> that you&#x27;ve discovered not merely another technical situation (which you&#x27;d know if you detected the same thing in radio waves), but a phenomenally advanced one.<p>So, if not an advantage, there is at least a meaningful <i>difference</i>.
