Radiometric dating half life examples
he generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years (plus or minus about 1%).This value is derived from several different lines of evidence.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.As you can see from Graph 2, the larger the coefficient the greater the 'starting amount'.Conversely, the smaller coefficients lead to smaller/lower 'starting amounts'.Learn about different types of radiometric dating, such as carbon dating.Understand how decay and half life work to enable radiometric dating.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.
Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
While these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it).
This lower limit is at least concordant with the independently derived figure of 4.55 billion years for the Earth's actual age.
In this first chart, we have a radioactive substance with a half life of 5 years.
