Shrinking sun indicates a young sun (Talk.Origins)
- The sun is shrinking at such a rate that it would disappear completely in 100,000 years. This would make it impossibly large and hot in the distant past if the sun is millions of years old.
- Morris, Henry M. 1985. Scientific Creationism. Green Forest, AR: Master Books, p. 169.
Talk Origins is correct on this point. Any significant shrinking of the sun would be due to gravity. This process would fluctuate even if gravitational collapse were the sun's only source of energy, since heat build up resist the tendency towards gravitational collapse. There would be suffice variation in the collapse rate so as that the collapse rate could not be used in a uniform manner to estimates the sun's maximum age.
