SUMMARY
The discussion centers on estimating the age of the solar system using the percentages of uranium isotopes found on Earth, specifically uranium-238 and uranium-235. The user attempted to calculate the age by using the formula (1/2)^n = 0.7/50, leading to an estimate of approximately 8.5 billion years. However, this calculation is incorrect, as it does not account for the differing half-lives of the isotopes, which are 6.5 billion years for uranium-238 and 1 billion years for uranium-235. Accurate age estimation requires a more nuanced approach that considers the initial abundance of both isotopes.
PREREQUISITES
