👤 whose
Whose calculations helped explain the Earth's age from radioactivity?
Quick Answer
Arthur Holmes was a pioneer of radiometric dating in geology. In the early 20th century, he used radioactive decay to estimate that Earth was billions of years old.
The Full Story
British geologist Arthur Holmes was among the first to apply radioactive decay to geological dating. In 1913, he published an early estimate for Earth's age using uranium-lead methods, and later work refined the picture. His research helped overturn much shorter age estimates that had dominated earlier geology. Holmes became one of the strongest advocates for a very ancient Earth, now known to be about 4.54 billion years old.
