For example, scientists search for and date the oldest rocks exposed on Earth’s surface.

Also, because Earth formed as part of our sun’s family of planets – our solar system – scientists use radiometric dating to determine the ages of extraterrestrial objects, such as meteorites.

They led to the discovery that certain very heavy elements could decay into lighter elements – such as uranium decaying into lead.

This work gave rise to a process known as radiometric dating.

Nowadays, scientists use radiometric dating of various sorts of rock – both earthly and extraterrestrial – to pinpoint Earth’s age.

Many great thinkers throughout history have tried to figure out Earth’s age.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14.



And by the end of the season, it comes full circle. Paul Ballard's reactions to what's going on -- how close are they to what you would do? Paul fears and hates this technology but is very curious about it. The implications and consequences of this technology being in the wrong hands, which incidentally it is -- and you'll see that it's leading that way -- of it just getting out there is really kind of scary. There was a lot of speculation that we were going to be canceled all the time. People are bonding, I think the writers are writing for the actors, and there's a lot of potential. If we get picked up for a full season, where can they go?… continue reading »
