Young earth evidence
Many scientific arguments can be used to show that the evidence is more consistent with a recent creation than an old Earth. Some arguments put forward in support of a recent creation simply put an upper limit on the age of the Earth, solar system, or universe, which are inconsistent with an ancient creation. For example, Russell Humphreys' argument based on the amount of salt in the ocean is designed to show the maximum possible age of the oceans based on uniformitarian assumptions, and thus shows that the oceans could not be as old as claimed; it is not designed to show the actual age of the oceans, and as such the resulting age, although far too great for the young Earth view, is not inconsistent with it.
Geomagnetic field decay
- Main Article: Geomagnetic field decay
Observations made of the strength of Earth's magnetic field over the last 150 years show that it is decaying, which puts an upper limit on the age of the Earth. If the decay is projected back 20,000 years, the heat produced by the electric current that generates the Earth's magnetic field would have liquefied the Earth. Naturally this would make life impossible. The best model for the Earth's magnetic field and observed data places the age of Earth at 6,000 – 8,700 years.
- Main Article: Pleochroic halos
Radioactive inclusions in rock often cause concentric spheres of discoloration due to the damage caused by alpha particles as they are emitted by the radioactive substance. Pleochroic halos are the scars of radioactive decay, particularly alpha decay. These scars appear as spheres (rings when views in cross-section) in the rock surrounding a decaying radioactive atom. The size of the halo is a signature of the energy of the emission and therefore the element and isotope involved. Creationists use these halos in several ways to suggest problems with the standard uniformitarian model.
- Main Article: Helium diffusion
One type of nuclear decay is the emission of Helium nuclei known as an alpha emission. Elements like uranium and thorium produce helium in zircons as a by-product of their radioactivity. This helium seeps out of (sic) zircons quickly over a wide range of temperatures. If the zircons really are about 1.5 billion years old (the age which conventional dating gives assuming a constant decay rate), almost all of the helium should have dissipated from the zircons long ago. But there is a significant amount of helium still inside the zircons, showing their ages to be 6000 +/- 2000 years. Accelerated decay must have produced a billion years worth of helium in that short amount of time.
- Main Article: Helioseismology
The core of the sun produces deuterium from hydrogen fusion at 5 million degrees K. The heat is transferred from the core by convection currents so it could reach surface in days, not a million years. It also leads to an age for the sun based on the deuterium/hydrogen ratio of the local interstellar medium of 6,000-12,857 years.
Accelerated Nuclear Decay
- Main Article: Accelerated Nuclear Decay
The main assumption of radiometric dating is that the decay rates are constant with time. If the decay rate has varied significantly over time then any date based on radioactive decay is worthless. However, if radioactive decay has been happening for Billions of years then there is insufficient argon diffusion, insufficient lead diffusion, insufficient helium in the air, and too much Helium in Rocks. Recent experiments commissioned by the RATE group indicate that "1.5 billion years" worth of nuclear decay has taken place, but in one or more short periods 4000 - 8000 years ago. This would shrink the alleged 4.5 billion year radioisotope age of the earth to only a few thousand years.
