Ask Mr. Cosmology

Time again to reach into the “Ask Mr. Cosmology” mailbag and see what readers want to know about . . . The Wonders of the Universe! First up, some questions from the comments portion of the previous installment of “Ask Mr. Cosmology.” Q: Is protest against God morally acceptable?

Fatherhood: From Here to Eternity
