A professor of astrophysics, writing for Answers in Genesis, has an article over there about the "Star of Bethlehem".
All the greates minds in all of science have pondered how to explain this phenomenon. Was it "a supernova, a comet, a massing of planets, a triple conjunction of Jupiter and Regulus (a bright star in the constellation Leo), or the astonishing conjunction of Jupiter and Venus on June 17, 2 BC."? I vote for (F): none of the above. While we humans may be trapped in these corporeal bodies, GOD is not! He is not bound by the laws of physics or time. And if He wants to create a star (like the other billion billion He already has) that sits over the top of a house in Bethlehem, He most certainly can. And we foolish humans are going to try to explian it!! Uhh, yeah. Right:)
