/article/extinct-radionuclides
Vernon R. Cupps, Ph.D. - What do you think of when you hear the word extinct? Dinosaurs, perhaps? Maybe saber-toothed cats, mammoths, or short-faced bears? We might also include the more recent Bali tiger, passenger pigeon, and West African black rhinoceros. There...

/article/two-different-calculations-hubble-constant
Vernon R. Cupps, Ph.D. - An interesting article1 on physics.org caught my attention. Its title is “Solved: The Mystery of the Expansion of the Universe.” But this can be misleading. The material covered really does not solve the problem of how the universe...

/article/science-vs-falsely-called-knowledge
Vernon R. Cupps, Ph.D. - Guard what was committed to your trust, avoiding the profane and idle babblings and contradictions of what is falsely called knowledge—by professing it some have strayed concerning the faith. (1 Timothy 6:20-21) The National Academy of...

/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...
