Talk:Counterexamples to an Old Earth (view source)
Revision as of 03:45, February 12, 2013
, 03:45, February 12, 2013→An increase in the frequency of large earthquakes is not a counterexample to an old Earth: new section
In this article there is a claim that the earth's magnetic field is weakening so fast, that extrapolating back in time, there is no room for an old earth since the intensity would have melted the earth. However, this isn't true. Earth's magnetic field changes strength and even reverses sometimes, (Gee et al. 2000; Gubbins et al. 2006) so this claim should be removed.

If large earthquakes are getting more frequent then there will be more of them in the future, and there were fewer of them in the past. This suggests that the Earth cannot exist for much longer in the future. But it doesn't say anything about how long the Earth has existed in the past. So this is clearly a bad example. I'll remove it if no-one objects. -- [[User:Occultations|Occultations]] 22:45, 11 February 2013 (EST)
