Isolated from the world, black hole survival for 40 days, after they saw the light of day…

Fifteen Frenchmen experienced 40 days of “isolation” in the cave, where they could not contact friends or relatives and were not informed of any new news. On April 24, the experience ended, and despite the volunteers’ fatigue, about two-thirds of them expressed a desire to remain in the cave.

A foreign scientific team conducted an experiment in France to study human beings facing extreme isolation, the experiment sent 15 volunteers into the Lombrives cave in the Pyrenees in southwestern France.

According to “France24” reported that the subjects of this experiment spent 40 days in the cave, the cave has the right amount of stored food, well water and tents, and even a bicycle generator, but they can not leave the cave, and can not check the time through a watch or cell phone, of course, can not contact people outside the cave, living a life without seeing the sun.

The cave constant temperature of about 12 degrees, 98% humidity, because there is no clock, the subjects through the sleep cycle to calculate the number of days, and many people have miscalculated the time, after 40 days have passed, they think they still have to stay in the cave 7 to 10 days, monitoring their scientists must also enter the cave to tell them that they can come out.

Today after the successful completion of the experiment, they left the cave in the applause of many people, because too long without seeing daylight, must wear goggles to protect their eyes. Scientists involved in the experiment Mauvieux (BenoitMauvieux) said that although the subjects looked tired, but two-thirds of the subjects said they could still stay in the cave for a longer period of time.

The study, which cost about 1.2 million euros, aimed to understand people’s behavior patterns under the concept of loss of referable time. Researchers remotely observed the sleep, social and behavioral patterns of cave dwellers. Subjects also swallowed a capsule, which contains a small thermometer and can transmit information to a computer, and then naturally expelled from the body.

Study leader Christian Clot said it was interesting to observe how the members kept the team together, adding that the group of subjects in the cave had to work together without the concept of time, which was very challenging.
