Kaluza-Klein theory, originally proposed in 1921 to 1926, has been described as a miraculous synthesis of Einstein’s gravitation theory with Maxwell’s equations of electricity and magnetism. In an approach which anticipated modern string theory, Kaluza and Klein added a fifth dimension of space to the three familiar spatial dimensions and one time dimension. The extension of Einstein’s theory to this fifth dimension then led naturally to Maxwell’s equations. The theory also naturally leads to a relation between the constant G of Newton’s law of gravitation and the fine structure constant α = e2/hc. This relation depends on the circumference of the compactified fifth dimension, so that variation in this circumference over the history of the universe could be viewed as variation in physical constants, such as the fine structure constant. If, during early creation week, say before the creation of man, such variations were to occur, they could lead to accelerated nuclear decay, thus adjusting isotopic abundances, without giving humans an unacceptable dose of radiation.
