What if even stars in a galaxy form a communicative network, communication meaning sending and reacting to signals on a purely physical basis which doesn't translate to a meaning to us yet. Gravity waves, electromagnetic signals, signals we are not aware of... I am not saying stars talk gossip but that there could be a signal exchange and a systemic reaction. We see it in practically all life forms on Earth and a in a way in the non-alive world as well when you look at the climate, for example.

I mean, when I speak I physically interact and transmit signals through air vibrations which we developed to both detect and interpret. Other perceptive "life" forms would have a hard time telling what we communicate about as well. Hell, we can barely if at all understand what other mammals communicate about despite their biophysical systems being incredibly similar to our own. Plants communicate with chemical signals and root/fungi networks.

Predicted pictures of the universe at large look eerily like the brain's structure as well.
