Ep 41 - Tree Rings, Sediment Varves, and Carbon-14

Young Earth advocates claim that dating methods using tree rings, annual sediment layers (varves), or carbon-14 cannot be trusted because they are all based on untestable assumptions. In fact, geologists have ways of testing ALL assumptions using the methods of empirical science. In this episode, I'll share my own contributions to the subject showing how tree rings, sediment varves, and carbon-14 can be combined in really, really cool ways to demonstrate that counts of tree rings and varves yield valid ages. To read more, check out the paper I wrote with fellow geologist and Christian brother, Ken Wolgemuth: Testing and Verifying Old Age Evidence: Lake Suigetsu Varves, Tree Rings, and Carbon-14.
