This method can even be used on dead trees that fell in a forest long ago.For example, the last 200 rings in the dead tree might match up with 200 rings early in the life of the living tree, so the two trees together can count back many years.The oldest reliably dated rock formation is in Greenland, where several different isotopes were used to find an age of 3.6 billion years.
These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years.
As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.
The periodic table shows the types of atoms that make up the world around us.
An element in the periodic table can come in different flavors called isotopes.
Once the rock hardens, however, all the Argon-40 is trapped in the sample, giving us an accurate record of how much Potassium-40 has decayed since that time.
So, if we find a rock with equal parts Potassium-40 and Argon-40, we know that half the Potassium-40 has decayed into Argon-40, and that the rock hardened 1.3 billion years ago.
The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old.
Astronomers and geologists have determined that the universe and Earth are billions of years old.
Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years.Tags: Adult Dating, affair dating, sex dating
