What do you mean "measure such a cycle?"<div>A billion year is a billion year. We have a way to "measure" it. I can even write it in scientific notation 10^ 9 years. </div><div>We know so many more cycles that the Maya could not even imagine. We know about solar cycles, we know about the precession of equinoxes, we know how long the the solar system will take to complete an orbit around the galactic center. We are gods of knowledge in comparison with these primitive people. It is time to stop worshiping these ancient civilizations as if they had some secret knowledge that didn't share with us. </div>

</div>Because, even if cycles repeat, the past cycles remain in the<br>
past.<br>
<br>
The months and days cycle in the new year, as the seasons do.<br>
But that particular year never happens again.<br>
<br>
Never again will the 2012 Olympics happen. Other Olympics<br>
will happen, but they will be products of their years, not 2012.<br>
<br>
Never again shall the dodo exist (unless someone somewhere<br>
has enough DNA to clone the species, and barring recreations<br>
that may be called "dodo" but are in fact distinct species).<br>
<br>
There may yet be a year in which no human being walks the<br>
Earth, but even discounting things like the current Mayan<br>
hysteria, the guesses on that range from less than a<br>
century through billions of years, so we do not yet know how<br>
to measure such a cycle.<br>
