The Dynamics of the Transition from Kardashev Type II to Type III Galaxies
We present a video of a simulation showing the expansion front of a technological species settling a Milky-Way-like galaxy. This class of simulation is described in Carroll-Nellenback et al. 2019. The animation we present illustrates how even very conservative rates of settlement ship launches and ship ranges can quickly lead to a galaxy endemic with technology, and how the rotational and peculiar motions of stars contributes to the expansion.
This video confirms and validates previous work showing that the centers of galaxies are promising search directions for SETI.
