He concluded that Earth was born 20 to 400 million years ago.Today’s scientists believe that answer is incorrect, but Kelvin’s calculations were in being based on logical thinking and mathematical calculation.He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.
It has been established through extensive experimentation that radioactive decay occurs at a constant rate. In this case, the initial condition is the amount of daughter isotope in the rock when it was formed.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.Scientists tried to determine Earth’s age via our planet’s layers of rock, which must have been built over time.You’ve seen these rock layers if you’ve ever observed a cut-away section of a mountain, perhaps because a highway runs through it. In the early part of the 20th century, scientists still weren’t sure.

Not because she was too young to name an Aretha Franklin song (which, like, come ON, Steely Dan); the idea that people are what pop culture references they know reduces falling in love to trading trivia. A lot of women have told me they won’t date younger men because of maturity issues, and that’s probably where the idea of a prohibitive "age gap" comes into play for a lot of people.
