Radioactive dating of rocks review and reinforce letter validating marriage
At the same time, the opportunity has been taken to round many more figures in the tables to the nearest thousand or some other convenient unit; this aids assimilation and facilitates comparisons.There is a special article on scientific research included in this issue.However, to read any clock accurately we must know where the clock was set at the beginning.Most people think that radioactive dating has proven the earth is billions of years old.Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant.After all, textbooks, media, and museums glibly present ages of millions of years as fact.Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!

Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
