Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.

To date an object, scientists measure the quantity of parent and daughter isotope in a sample, and use the atomic decay rate to determine its possible age.

At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column.

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.

There are over forty such techniques, each using a different radioactive element or a different way of measuring them.

Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts.

Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old.

It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.

    Some ten years later, and you'll be shocked to learn that higher cable TV rates and the death of niche channels... The Wall Street Journal this week penned an interesting look at how cable companies are increasingly culling lesser-viewed channels from the cable lineup, largely to make way for more expensive programming (read: mostly sports). But people typically watch only about 15 a week, according to Nielsen. Nearly 70 channels that collect an average of of Americans’ monthly cable bills each accounted for about 0.5% or less of total TV viewing in January, according to a WSJ analysis of Nielsen and Kagan data." As broadcasters demand more and more money for the same content, cable providers have started either eliminating lesser watched channels from their cable lineup entirely, or shoveling these channels off into higher-priced bundles in a desperate attempt to stave off inevitable evolution. Customers are tired of paying 0 per month for 200 (largey unwatched) channels, and are increasingly fleeing to streaming competitors -- resulting in 2016 seeing the highest cord cutting rates on record.
