/article/revisiting-isochron-age-model-part-2
Vernon R. Cupps, Ph.D. - Last month’s article explored initial problems with the isochron age model, which has been the standard radioisotope dating method.1 We will now dive even deeper into the isochron dating model. In part 1, we examined the linear equation in...

/article/revisiting-isochron-age-model-part-1
Vernon R. Cupps, Ph.D. - Radioactive dating is based on the decay rate of a starting radioactive isotope (the parent) into its stable counterpart (the daughter). An age is assigned to an object by measuring the quantity of each isotope and calculating how long it would...

/article/fissiontracks
Vernon R. Cupps, Ph.D. - Highlights • Nuclear fission—atom splitting—is used to date ancient rocks. • The various fission dating methods show results that are not only highly inconsistent with...

/article/nuclear-fission-dating-methods-are-unreliable
Vernon R. Cupps, Ph.D. - Have you ever pulled apart a large mass of taffy and watched it break into two approximately equal masses? This is an illustration of what happens in the subatomic world when a 238U or 235U atom undergoes splitting, or fission. Nuclear fission is...

/article/strontium-ratio-variation-in-marine-carbonates
Vernon R. Cupps, Ph.D. - In 1948, geologist F. E. Wickman predicted that the decay of 87Rb (a rubidium isotope) in the earth’s crust and mantle would be reflected in a related increase in the 87Sr/86Sr (two strontium isotopes) in seawater as well as in...

/article/helium-retention-zircons-demonstrates-young-earth
Vernon R. Cupps, Ph.D. - Zircons are tiny crystals of zirconium silicate (ZrSiO4) that originate in igneous rock, which forms when volcanic magma cools. It’s a very stable mineral that melts at 2550°C. Zircon is harder than quartz and almost as hard as diamond....

/article/baryon-conservation-and-the-antimatter-mystery
Vernon R. Cupps, Ph.D. - Everything is made of matter. Matter is made of atoms, and atoms are made of smaller particles. Baryons are one of these subatomic particles, and the most common are protons and neutrons. They’re important because they make up most of the...

/article/new-findings-challenge-secular-dating-models
Vernon R. Cupps, Ph.D. - Two recent news stories, one from the Carnegie Institute for Science1 and another from an issue of Nuclear Technology,2 shed light on an icon of “deep time” radioisotope dating—the Isochron model. The former reported evidence...

/article/radiohalos-natures-tiny-mysteries
Vernon R. Cupps, Ph.D. - Figure 1. Some typical examples of different radiohalos found in granitic rocks, from volume 2 of the Radioisotopes and the Age of the Earth (RATE) study.1   Radiohalos are minute darkened circular zones around tiny...

/article/lithium-milky-way-halo-stars
Vernon R. Cupps, Ph.D. - A recent news article1 reported that certain types of stars2 in our Milky Way Galaxy have more lithium (Li) in their stellar atmosphere than the current models predict. Before 1982, it was generally believed that Li abundances in...
