Aardsma Research & Publishing [ARP] is a private research group located in Loda, Illinois. Dr. Gerald Aardsma founded ARP in 1995 in order to pursue his work at the interface of science and the Bible, full time. Initially he focused on solving chronological difficulties between radiocarbon and the Bible’s ancient history. In 2000, once those difficulties had been solved, his focus shifted to research into the cause of aging in the human body, starting from the longevity data given to us in the book of Genesis. ARP has several divisions, including Dr. Aardsma’s Vitamins.
