Encyclopedia
Dr. David Russell Humphreys is an American physicist and creationist author. He has offered a young Earth creationist cosmological model to deal with the distant starlight problem.

Cosmological model

Humphreys' book, Starlight and Time, presents an alternative cosmological model to the currently accepted Big bang
Big Bang
The Big Bang theory is the prevailing cosmological model that explains the early development of the Universe. According to the Big Bang theory, the Universe was once in an extremely hot and dense state which expanded rapidly. This rapid expansion caused the young Universe to cool and resulted in...

 to postulate that time ticked at different rates during the universe's origin. In other words, according to his theory, clocks on earth registered the six days of creation while those at the edge of the universe counted the approximately 15 billion years needed for light from the most distant galaxies to reach earth. The model places the Milky Way galaxy relatively near the center of the cosmos.

Criticism

His model has been criticized by other scientists and old earth creationists such as Hugh Ross

, as some icy chunks are occasionally flung far away by interactions with large planets."

Sea Salt Issue

Thomas also criticised Humphreys' idea that there is "not enough sodium in the sea" for a several billion year old sea, writing, "Humphreys finds estimates of oceanic salt accumulation and deposition that provide him the data to "set" an upper limit of 62 million years. But modern geologists do not use erratic processes like these for clocks. It's like someone noticing that (A) it's snowing at an inch per hour, (B) the snow outside is four feet deep, and then concluding that (C) the Earth is just 48 hours, or two days, in age. Snowfall is erratic; some snow can melt; and so on. The Earth is older than two days, so there must be a flaw with the "snow" dating method, just as there is with the "salt" method."

Helium Problems

Geologist Kevin Henke has criticised Humphreys for stating that "zircons from the Fenton Hill rock cores... contain too much radiogenic helium to be billions of years old." Henke wrote that the equations in Humphreys' work "are based on many false assumptions (isotropic diffusion, constant temperatures over time, etc.) and the vast majority of Humphreys et al.s critical a, b, and Q/Q0 values that are used in these 'dating' equations are either missing, poorly defined, improperly measured or inaccurate." Humphreys has replied to Henke's criticisms.

Earth Cooling Model

Scientists Glenn Morton and George L Murphy have dismissed Humphreys' cooling model as "wrong" because "it is ineffective, it is falsified by observational data, and it is theologically flawed." First, in a classical model for a harmonic oscillator (like a particle oscillating in a crystal), "the particle does not lose energy to the cosmic expansion." Second, Humphreys' model "is too slow to be useful to the creationist agenda." Thirdly, "there would be visible effects in the spectra of light emitted during the Flood, including those from stars a few thousand light years away in our own galaxy. A change in the energy levels of atoms (which this idea would entail) would change the frequencies at which light is emitted in a fashion that would be observable. The lack of such observations rules out Humphreys' cooling mechanism as a reasonable possibility." Lastly, they criticized it for contradicting the theological foundation Humphreys uses in another publication.
