On April 24，2021，15 people came out of a cave （洞穴） in France.As part of an experiment（實驗），they spent the last 40 days underground.
The "Deep Time" experiment was run by the Human Adaptation Institute （HAI）.The HAI is led by Christian Clot who took part in the experiment with seven other men and seven women.They went into the Lombrives cave together.It is one of the largest caves in Europe.
The 15 people lived inside the dark cave for 40 days with no connection to the outside world.It was cool inside the cave and the air was very wet.The campers slept in tents.If they wanted light，they had to make it themselves by riding a special bike.They had to get all of their water themselves by pulling it up from a well（井）deep below the cave.
One of the most important parts of the Deep Time experiment was studying how our brains record time when there are no outside clues，like clocks or the movement of the sun.The campers could sleep and eat whenever they wanted.Over time，different people developed different schedules（日程安排）.Because there were no clocks，they counted the days according to how many times they slept.
During their time in the cave，the campers took on different small jobs and projects.Seeing how they worked together was another part of the experiment.For many campers，working on group projects was especially hard，since it was very difficult to set the meeting time.
Finally，at 10：30 on the morning of April 24，the campers left the cave and saw sunlight for the first time in 40 days.
