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.
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.
They led to the discovery that certain very heavy elements could decay into lighter elements – such as uranium decaying into lead.
His work has been published online and in various newspapers, including "The Cornish Times" and "The Sunday Independent." Grahams specializes in technology and communications.
