Can you shed some light on this creationist claim?

Question

Posted earlier, as evidence against an old Earth:

"The Earth's Electromagnetic field is decreasing by half every 1400 years and would have liquefied the earth just 20,000 years ago"

However, in reality:

The earth's magnetic field is known to have varied in intensity (Gee et al. 2000) and reversed in polarity numerous times in the earth's history. This is entirely consistent with conventional models (Glatzmaier and Roberts 1995) and geophysical evidence (Song and Richards 1996) of the earth's interior. Measurements of magnetic field field direction and intensity show little or no change between 1590 and 1840; the variation in the magnetic field is relatively recent, probably indicating that the field's polarity is reversing again (Gubbins et al. 2006).

Empirical measurement of the earth's magnetic field does not show exponential decay. Yes, an exponential curve can be fit to historical measurements, but an exponential curve can be fit to any set of points. A straight line fits better.

T. G. Barnes (1973) relied on an obsolete model of the earth's interior. He viewed it as a spherical conductor (the earth's core) undergoing simple decay of an electrical current. However, the evidence supports Elsasser's dynamo model, in which the magnetic field is caused by a dynamo, with most of the "current" caused by convection. Barnes cited Cowling to try to discredit Elsasser, but Cowling's theorem is consistent with the dynamo earth.

Barnes measures only the dipole component of the total magnetic field, but the dipole field is not a measure of total field strength. The dipole field can vary as the total magnetic field strength remains unchanged.

Does the creationist claim seem valid to you, in light of these facts? Is there something creationists know about but scientists are missing?

Answer 1

if it varies, what or who makes in vary? Coz it does sound like a regulation of some sort to me

Answer 2

Yeah...its complete crap. The magnetic field varies in both directions and even flips over occasionally. The field is the result of the hot metals in the Earth, not the cause of it.

Answer 3

The earth's magnetic field is actually known to reverse every so many 10s of thousands of years, so this phenomenon of it reversing actually makes the claim that it's decrease would liquefy the earth moot.



What really needs light shed on it is why someone would consider a creationist claim valid. :D

Answer 4

Yep. You do the mathematics it comes out to below a million/2 the area over 4.5 billion years they're additionally assuming the fee is linear. it is not. The regression will opposite in approximately 10 billion years at form of two times the area that's now. Or a minimum of it might if it wasn't interrupted by utilising the solar going purple great earlier then.
