This Man Proved Time Is An Illusion. In 1972 he entered a cave chamber 440 feet below the ground, alone and isolated from any natural light & clocks. For six months he removed from all time references which led to his discovery of a human time warp and slowing down time. He found that without time cues, several people including himself adjusted to a 48-hour rather than a 24-hour cycle. In 1962, a French scientist named Michel Siffre lived alone in a cave for two months, with no clock, calendar, or sunlight. He only slept and ate when he felt like it, to see how living without time would affect the body's natural rhythms. Over the next ten years, he set up more than twelve similar experiments. In 1972, he went back into a cave in Texas for six months. His work helped start the study of human biological clocks. A thread to slow your body time🧵
