Gerald Schroeder is "an MIT-trained scientist who has worked in both physics and biology", and now spends his time "melding" scientific theories with the Bible. Here he tries to reconcile the six literal 24-hour days of creation from Genesis with all that pesky scientific evidence showing that the universe is in fact billions of years old. He has a wacky theory involving general relativity and time-dilation effects that, according to him, proves both viewpoints are simultaneously true:
Once you come from Adam, the flow of time is totally in human terms. Adam and Eve live 130 years before having children! Seth lives 105 years before having children, etc. From Adam forward, the flow of time is totally human in concept. But prior to that time, it's an abstract concept: "Evening and morning." It's as if you're looking down on events from a viewpoint that is not intimately related to them.
Elsewhere, he states:
As a nuclear physicist who has served on the staff of MIT and as a member of the U.S. Atomic Energy Commission, I have undertaken extensive research of the natural world in light of the Biblical account. My conclusion? I see no contradiction between them whatsoever.
It's amazing what lengths creationists will go to in order to reconcile scientific facts with what's written in their holy book. This guy is taking a fresh approach - just accept both sides of the argument and "meld" them together. I guess if you're going to believe all 1200 pages of nonsense in the Bible, a few extra pages of pseudo-scientific twaddle like that found on Gerald's website should be pretty easy to swallow.
