Extreme Experiment Confines 15 People to Secluded Cave for 40 Days

In an attempt to gather data on the effects of long-term isolation without any notion of time on the human brain, 15 volunteers will spend 40 days in a cave in Ariège, in the south of France.

In what is being described as a “world first”, eight men and seven women will be spending 40 days isolated in a large cave, without phones, watches or any type of device that could help them tell time. The project is called Deep Time and it’s the brain child of Franco-Swiss explorer Christian Clot, who himself is one of the participants. He along with the 40 other volunteers will started their “timeless life” experiment today, and will be spending the next 40 days isolated in a large cave in the Pyrénées mountains. They are all equipped with sensors allowing a dozen scientists to follow them from the surface.
