In the 1970s, young Earth creationist Robert V. Gentry proposed that radiohaloes in certain granites represented evidence for the Earth being created instantaneously rather than gradually. This idea has been criticized by physicists and geologists on many grounds including that the rocks Gentry studied were not primordial and that the radionuclides in question need not have been in the rocks initially. Thomas A. Baillieul, a geologist and retired senior environmental scientist with the United States Department of Energy, disputed Gentry's claims in an article entitled, "'Polonium Haloes' Refuted: A Review of 'Radioactive Halos in a Radio-Chronological and Cosmological Perspective' by Robert V. Gentry." Baillieul noted that Gentry was a physicist with no background in geology and given the absence of this background, Gentry had misrepresented the geological context from which the specimens were collected. Additionally, he noted that Gentry relied on research from the beginning of the 20th century, long before radioisotopes were thoroughly understood; that his assumption that a polonium isotope caused the rings was speculative; and that Gentry falsely argued that the half-life of radioactive elements varies with time. Gentry claimed that Baillieul could not publish his criticisms in a reputable scientific journal, although some of Baillieul's criticisms rested on work previously published in reputable scientific journals.
=== Astronomy and cosmology ===
==== Creationist cosmologies ==== Several attempts have been made by creationists to construct a cosmology consistent with a young Universe rather than the standard cosmological age of the universe, based on the belief that Genesis describes the creation of the Universe as well as the Earth. The primary challenge for young-universe cosmologies is that the accepted distances in the Universe require millions or billions of years for light to travel to Earth (the "starlight problem"). An older creationist idea, proposed by creationist astronomer Barry Setterfield, is that the speed of light has decayed in the history of the Universe. More recently, creationist physicist Russell Humphreys has proposed a hypothesis called "white hole cosmology", asserting that the Universe expanded out of a white hole less than 10,000 years ago; claiming that the age of the universe is illusory and results from relativistic effects. Humphreys' cosmology is advocated by creationist organisations such as Answers in Genesis; however because its predictions conflict with current observations, it is not accepted by the scientific community.
==== Planetology ====
Various claims are made by creationists concerning alleged evidence that the age of the Solar System is of the order of thousands of years, in contrast to the scientifically accepted age of 4.6 billion years. It is commonly argued that the number of comets in the Solar System is much higher than would be expected given its supposed age. Young Earth Creationists reject the existence of the Kuiper belt and Oort cloud. They also argue that the recession of the Moon from the Earth is incompatible with either the Moon or the Earth being billions of years old. These claims have been refuted by planetologists. In response to increasing evidence suggesting that Mars once possessed a wetter climate, some creationists have proposed that the global flood affected not only the Earth but also Mars and other planets. People who support this claim include creationist astronomer Wayne Spencer and Russell Humphreys. An ongoing problem for creationists is the presence of impact craters on nearly all Solar System objects, which is consistent with scientific explanations of solar system origins but creates insuperable problems for young Earth claims. Creationists Harold Slusher and Richard Mandock, along with Glenn Morton (who later repudiated this claim) asserted that impact craters on the Moon are subject to rock flow, and so cannot be more than a few thousand years old. While some creationist astronomers assert that different phases of meteoritic bombardment of the Solar System occurred during "creation week" and during the subsequent Great Flood, others regard this as unsupported by the evidence and call for further research.
