The Age of the Earth — Does it Really Matter? - Part Two
Seegert, Jay An excerpt from Let There Be Light [The following is a continuation of the article in the TBC August 2014 issue by Jay Seegert of the Creation Education Center. Jay now takes a closer look at the various scientific methods of observation regarding the age of the earth.] Earth’s Magnetic Field The earth is like a giant magnet, and scientists have been measuring its strength for more than 170 years. From these measurements, they have determined that the earth’s magnetic field has a half-life of about 1,400 years. This simply means that every 1,400 years, it loses half of its strength. The most interesting aspect of this phenomenon is not related to the future of the field but its past. About 1,400 years ago, the magnetic field would have been twice as strong as it is today. Going back another 1,400 years (c. 800 B.C.) it would be four times as strong. A greatly increased magnetic field means a greatly hea...
