The age of the Earth?

  1. Oct 4, 2007 #1
    I'm in a college Physics AP course, and I was wondering:

    Is there any way to calculate the age of the Earth using just a easily understandable physics method?

    Carbon-14 has a half-life of 5730 years, so it is not applicable to dating the Earth. Those rocks were never alive and are a lot older than 60,000 years. They do, however, contain uranium and thorium. Those elements can be used to date the rocks.

    Speculation: consider the radioactive core as a nuclear reactor to date the Earth's coalescence (not so easy a method).

    I think Tony meant to say radiometric dating, not Carbon-dating, judging from the link.
