A metallicity- and SFR-dependent galaxy-wide IMF in semi-analytical models reproduces the mass-metallicity relation and quenched ellipticals more accurately than constant-IMF models, with self-regulation set by gas accretion rates near the Hubble constant.
Civilizations can achieve galaxy-spanning reach within biological lifetimes via time-dilated orbits near black hole photon spheres using classical general relativity, with a Type II civilization enabling 10^4 dilation factors.
Proposes that 10 years of 0.5 μas astrometry of Proxima Centauri can distinguish MOND from Newtonian gravity in the low-acceleration regime.
