Ja.  We could start by thinking of the things that every spacefaring lifeform would have discovered.  Humans do not own mathematics, but we are the only species on the planet using it.  That in itself is astonishing once you think about it.

We could perhaps think of all the reasons why a tech-enabled lifeform 400 LY distant would be radio silent.  I can come up with some.


John we have a lot of work to do on your notion of the information content of a volume of space being a function of the surface area of the sphere.  That in itself has some profound consequences.  As the sphere scales up, the information content increases as the square while the latency increases linearly.  That observation requires deep thought.
