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.
It stated that this is possible because each event melted part of it, and thus the atomic clock of that part was reset.
So how does melting a stone cause decayed radioactive elements to return to their original form? The same question applies to dating the solar system.
This conclusion is not based on just one measurement or one calculation, but on many types of evidence.
Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under further reading.
Because of radioactive decay, the material starts out with a larger amount of daughter isotope than is chemically favorable, so some of it will escape to bring the material to equilibrium.
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.
Most people, even the experts in the field, forget the assumptions on which radiometric dating is based.
Radioactive Dating There are basically two different kinds of radioactive dating methods.
Shouldn't the radioactive elements have been decaying for 8 billion, 12 billion years; ever since they were blasted into existence in ancient supernovae?
