The Hawaiian Islands offer a fascinating natural laboratory to test young earth and old earth models, including the reliability of radiometric dating. Both models have clear expectations that can be compared with what we actually find in nature, and only one model fits the evidence. Five scientific evidences that show the impossibility of a single flood carving the Grand Canyon.

Learn about three methods scientists have used to determine the age of the Earth: tree rings, lake varves, and radiometric dating. Introduction Astronomers and geologists have determined that the universe and Earth are billions of years old. Age of the Earth and solar system from radiometric dating In your high school science classroom, you may have seen a large poster of the periodic table hanging on the wall.

Age of galaxies from the travel time of light What about the ages of stars and galaxies, and the age of the whole universe? Age of the universe from expansion Not only can astronomers measure the distance of galaxies, they can measure how galaxies are moving. How Do We Know? PDF Roger C.
