The alleged device, which according to many is nothing more than science fiction, was purportedly built in the 1950s by a team of scientists led by Father Pellegrino Maria Ernetti (1925-1994), an Italian physicist who eventually became a priest.

It is worth mentioning as well that he enlisted the help of twelve of the world’s most prominent scientists - who wished to remain anonymous. Of those twelve, two were named years after they died, one Nobel laureate Enrico Fermi, and one Werner Von Braun of Nasa and Nazi fame.

Father Ernetti was a Benedictine priest, scientist, and world-class authority on "archaic" music (pre-Christian to 10th century A.D.). He claimed to have yoked quantum physics to the occult arts to construct a time machine: the Chronovisor.

Is the Vatican suppressing the full truth of Father Ernetti’s life and achievements?

In 1988, the Vatican issued a decree in which it warned that anyone using an instrument with such characteristics would be excommunicated. To many, this was an unnecessary warning since, according to the church, the chronovisor never existed. So why issue a warning for just another hoax?

Reports by Father Ernetti suggest that whoever uses the device is able to capture and record specific locations, important events, and track noteworthy individuals. 

He revealed that it worked by "processing residual electromagnetic radiation left over by numerous processes," though he gave few details. 

Father Ernetti remained secretive and stated he was not at liberty to reveal further details about the Chronovisor. Read more on this device here.
