CMI supporter Joni from Finland asks about an old earth argument he encountered from a Finnish evolutionist. Dr Jonathan Sarfati (CMI–US (formerly Australia)) responds:

How do you respond to this?

The age of the sun can be calculated with accuracy nowadays. The fusion models of the sun can be calculated with computers and they give a compatible brightness compared with observations. In addition to this model, models give the ratio of helium and hydrogen (He/H) in a function of radius. So called helioseismology has been able to provide an accurate ratio of He/H and the internal composition of the sun, thus the sun’s age has been able to measure with accuracy.

Helioseismology is an phenomenon, where the sun’s surface undulates in a timescale of minutes and hours, this can be seen from the spectral-lines (part of the surface comes towards and some goes in the opposite direction and a Doppler-transition is seen ): (picture below)

These sound waves travel through the sun and are dependent on the internal structure and the ratioprofile of He/H, etc.

This internal undulation and its “spectral analysis” gives quite tight margin for models of the sun, for its internal structure and for the age of the sun so, that the age of the sun was calculated in 1999 to be 4.66±0.11 billion years.

Actually, this question has already been addressed in my book Refuting Compromise, either directly or by logical implication. The relevant chapter (#5) was checked by a Ph.D. stellar astronomer, Danny Faulkner; and a Ph.D. solar astrophysicist, Jason Lisle….
