In case you forgot (and how could you?), temperatures that July afternoon reached a soul-shattering 104 degrees. It was a meteorological event of biblical proportions, appropriately foreshadowing the theme of this Saturday’s opening reception at MG-GM: The History of the Universe Part Two: The End. From 7-11 p.m. the gallery and a number of local artists will whisk you to a mixed-media universe in its death-throes. Go see it before it’s too late. After all, it is 2012. 7-11 p.m. Saturday Aug. 4 at Museum Gallery/Gallery Museum. 2161 Central Ave., Brighton. mg-gm.com.
