Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.As the name implies, relative dating can tell which of the two artifacts is older.The Mayan calendar used 3114 BC as their reference.More recently is the radiocarbon date of 1950 AD or before present, BP.Heisenberg's uncertainty principle states that a system can never have precisely zero energy and since energy and mass are equivalent, pairs of particles can form spontaneously as long as they annihilate one another very quickly.The less energy such a system has, the longer it can stick around.If you take inflation into account, which physicists think caused rapid expansion in the early universe, we begin to see why MIT physicist Alan Guth calls the universe the "ultimate free lunch." You can read the full story here or check out the rest of our Existence special.In our previous animated explainers, you can find out why free will is an illusion or how animals shaped the human mind.

How can you make any conclusions about rock layers that make such a crazy arrangement?This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.It implies that relative dating cannot say conclusively about the true age of an artifact.It is possible to tell the number of years ago a particular rock or archeological site had been formed.Two broad categories of classification methods are relative dating and absolute dating.
