galaxies and star systems God decided that They would put some humans on the third planet from an insignificant star on a little arm of a middling

cause affront to the tripartite godhead warranting separation of Gods grace from all their offspring; then we are left with people being chosen from way back before the Big Bang to do some terrible things like killing babies or betraying Jesus who was chosen on the same non date (time didn't exist before creation) to die in a fairly nasty fashion and thereby appease the righteous wrath of himself and his fellow Trinitarians
by paying a penalty as a substitute for all future sins (of believers?)

Other scenarios involve gravitational perturbations, either
caused by passing stars, a solar system entering and exiting our
galaxy's gravitationally dense spiral arms, or even via interactions with dense molecular clouds.
Not only is this a new record, the object also serves an important purpose: the amount of distortion
caused by the lensing
galaxy allows a direct measurement of its mass.
Another experiment there, the South Pole Telescope, reported finding B - mode polarization last year, although the signal it saw was at a different angular scale across the sky and was clearly due to the known process of gravitational lensing (a warping of light
caused by massive objects) of the CMB
by large
galaxies, rather than the primordial gravitational waves seen here.
