and yet scientists did not investigate any of examples of miracles in the link that i posted which were all physical observable manifestations.

Marian Apparition in Zeitoun

Zeitoun, Egypt, 1968-1971

From April 1968 to May 1971, more than 100,000 people reported observing Virgin Mary apparitions above a Coptic Orthodox Church at Zeitoun, Egypt. Witnesses' descriptions varied between two main types: small bright, short-lived lights nicknamed “doves,” and more enduring, less intense, diffuse patches of glowing light (Johnston 1980). Canadian neuropsychologist Michael Persinger of Laurentian University and his American colleague John Derr (1989) analyzed seismic activity in the region from 1958 to 1979, and found an unprecedented peak in earthquakes during 1969. They state that “The 'narrow' window of significant temporal relationship between luminous phenomena and earthquakes is within the classic time frame of more acceptable antecedents (e.g., microseismic activity) of imminent earthquake activity.” It appears that the Marian observers were predisposed by religious background and social expectation to interpreting the light displays as related to the Virgin Mary.

Incorruptible Corpses

Over the last 15 years, however, a new view of the Incorruptibles has begun to emerge. At the Vatican's request, Italian pathologists, chemists, and radiologists have been poring over the bodies of the ancient men and women interred in church reliquaries. Charged with gleaning new information about the lives of the saints and assisting in the conservation of sacred remains, they have also brought science to the altars of Europe's cathedrals. Already, they have examined more than two dozen saints and beati, shedding light on the mystery of their preservation.

Therese Neumann

Scientists and skeptics do not believe that Neumann performed genuine miracles. According to skeptical investigator Joe Nickell on one occasion Neumann claimed to have healed herself from blindness, but whilst "blind" she was examined and her pupils responded normally to light. Nickell suspected that Neumann's claims were performed by "hysterical hypochondria" or "outright fakery".[13]

By 1928 the church authorities had investigated Neumann's alleged stigmata. A professor who was monitoring her noted that blood would only appear from her wounds when he was asked to leave the room. He reported the behavior as suspicious commenting that something "needed to be hidden from observation."[13]

A psychoanalytic study of Neumann has suggested that her stigmata resulted from post-traumatic stress symptoms expressed in unconscious self-mutilation through abnormal autosuggestibility.[14]

Researcher Ian Wilson found the inedia claims of Neumann suspicious. He noted that "Therese had a vigorous, stocky build throughout most of this time, and all reason tells us that it would be impossible to survive so long without food or drink."[15]
