  • Interesting fact: Earth's magnetic field has been weakening. It seems to have lost 15% of its strength since 1670. At the present rate of decrease, it will reach zero in 2,000 years. Between the years 3500 and 4500, the magnetic field will not be sufficiently strong enough to ward off charged radiation from outer space.
