For the same reason German has not swept the world. Light from one “edge” of the universe has yet to reach the edge directly across from Same reason we need shifts in gravity to detect planets Diffusion, attenuation of signal given all the other stuff are physical properties of the universe, they’re properties in us The universe prefers tribalism; a quasar far off over there, neutron star far off over there. There are a lot of meat suits who refuse to propagate the signal. Doesn’t mean it won’t shine bright in some local part of space.
