Now Carpinteri's team, through mechanical and chemical experimentation, hypothesizes that high-frequency pressure waves generated in the Earth's crust during earthquakes are the source of such neutron emissions.This is based on their research into piezonuclear fission reactions, which are triggered when very brittle rock specimens are crushed under a press machine.In the process, neutrons are produced without gamma emissions.Analogously, the researchers theorize further that neutron flux increments, in correspondence to seismic activity, should be a result of the same reactions.
The earliest undisputed historical records place the Shroud in Lirey, France, between 13.
(Phys.org) —An earthquake in Old Jerusalem might be behind the famous image of the Shroud of Turin, says a group of researchers led by Alberto Carpinteri of the Politecnico di Torino in Italy in an article published in Springer's journal Meccanica.
They believe that neutron radiation caused by an earthquake could have induced the image of a crucified man – which many people believe to be that of Jesus – onto the length of linen cloth, and caused carbon-14 dating done on it in 1988 to be wrong.
That characterization is based largely on debunked carbon-14 tests.
In 1988 they led researchers to estimate a date of origin between 12, but the samples tested came from edges that were added to fortify the cloth after it was damaged in a fire in 1532. Heated silver in the Shroud’s storage box created distracting shapes that now border the man’s image.
