Worse still, sometimes they want to know how evolutionists use Carbon-14 to date dinosaur fossils!
A painting in the Guggenheim collection initially attributed to French modern artist Fernand Léger has languished out of view for decades after it was suspected to be a fake.
Now scientists have confirmed that the artwork is a indeed forgery; in a first, they detected faint signatures of Cold War-era nuclear bombs in the canvas that reveal the painting was created after Léger's death.
[Faux Real: A Gallery of Forgeries] To solve this art historical enigma, scientists from the Italian Institute for Nuclear Physics (INFN) took a tiny piece of the canvas from an unpainted edge of the work.
The team used a particle accelerator to measure the concentration of carbon 14 (an isotope of carbon that has more neutrons than normal carbon 12) in the fabric, which would in turn allow them to determine when the canvas was produced, or more specifically, when the cotton was cut to make the canvas.
The influential American art patron Peggy Guggenheim bought the painting, believing it to be part of Léger's "Contraste de Formes" (Contrasts of Forms), an abstract series created between 19 that breaks up figures into schematic units.
(Léger was a contemporary of Pablo Picasso.) In the 1970s, Léger scholar Douglas Cooper voiced serious skepticism about its authenticity. Guggenheim Foundation, the current steward of the painting, has never exhibited nor catalogued the artwork.
other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.
Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.
