The Physics of Resurrection
First Things — never a publication to shy away from tough issues — has a commentary on the physics of the resurrection. Stephen Barr holds that it’s a tough problem, even for God.
…the resurrection of the body involves “God’s reassembling at least some of the numerically same particles that once were in our living bodies when we were alive.” That seems to me to be a very problematic notion from the point of view of modern physics—indeed, strictly speaking, a meaningless notion.
But God, being omnipotent, could do this right? He could, but Barr makes the crucial point that if the afterlife is a world of continual miracles, then it has no laws bounding its behavior and thus is not a world at all. Probably the most accessible answer is that the world to come is not recognizable nor understandable by normal human (earthly) intelligences, and is therefore incomprehensible until we get there.
