Do evolutionary scientists really think, as Rev Gish would like us to believe they do, that the physical laws of the universe are changing? No, of course they do not. Rev Gish is merely lying again, or is grossly incompetent (you decide). When the universe was approximately 10-34 of a second old, one of the four forces (the strong force) became constant and unchanging. By 10-10 of a second, the other three forces (the weak force, the electromagnetic force, the gravity force) separated and became distinct. While it took considerably longer (300,000 years) for the universe to cool enough to form some of the mater we are familiar with, the four forces were already in place: they have not changed, nor will they change, for at least 65,000,000,000 years (if the universe is closed), or never (if the universe is open).
Scientists know these facts. Rev Gish claims they do not. Why would Rev Gish lie to you about this?
