Where and by whom was the radiocarbon dating method developed

05 May

The earliest experiments in radiocarbon dating were done on ancient material from Egypt. Libby’s team obtained acacia wood from the 3rd Dynasty Step Pyramid of Djoser to test a hypothesis they had developed.Libby reasoned that since the half-life of C years, the Djoser sample’s C14 concentration should be about 50% of the concentration found in living wood (for further details, see Arnold and Libby, 1949). Subsequent work with radiocarbon testing raised questions about the fluctuation of atmospheric C14 over time.That’s because, according German historians Herbert Illig and Hans-Ulrich Niemitz, it never did. Using lunar phases, hunters and gatherers developed a rudimentary calendar in the fields of Scotland to track the lunar months and changing seasons.As the world’s civilizations evolved, they each developed their own individual calendars based on lunar phases and harvest seasons.However, when this is done, the results can be astonishing, to say the least.Whereas the commonly held and taught gravitational model of the Big Bang has presented problem after problem and required the invention of unseen dark matter, force, and energy, work with plasma filaments has demonstrated that what we see in space exactly matches what happens in the lab.” It may have been after a wild night of partying, or a great conversation with a friend, or while intensely concentrating on a project.

Everyone has had a moment in their life where they’ve muttered to themselves, “Wow, where did the time go?
