The Age of the Earth

Authors


Abstract

Time is the most elusive of fundamental concepts. Yet we are in every sense creatures of time, the progeny of 4.5 billion years of it. Some of us spend our lives trying to understand time. And if that has so far proved impossible, at least in post-Newtonian time we have produced an apparently reliable measure of just how much time has elapsed since planet Earth condensed from the solar whorl.
