🕳️⏳ What Happens When Time Disappears? In 1962, geologist Michel Siffre locked himself inside a dark cave for two months — no sunlight, no clock, no calendar. He counted each sleep as “one day.” When he finally came out, he thought it was August 20… It was actually September 14. 😳 Without light or time cues, his body clock drifted beyond 24 hours — sometimes stretching toward nearly 48-hour cycles. Turns out, time isn’t just on your phone… it’s wired inside you. And without signals from the Su

In 1972, French geologist and speleologist Michel Siffre embarked on one of the most fascinating human experiments ever attempted. He spent six months completely alone in a cave in Del Rio, Texas, with no sunlight, no clocks, and no contact with the outside world. Cut off from all external cues, Siffre lost track of time entirely, sleeping and waking according to his body’s natural rhythm rather than day and night. What he discovered reshaped our understanding of circadian biology, showing how t

In 1972, French geologist and speleologist Michel Siffre descended 440 feet into a cave near Midland, Texas, leaving behind every conventional marker of time. There were no clocks, no sunlight, and no connection to the outside world. For six months, Siffre lived in complete isolation as part of a radical scientific experiment designed to understand how humans perceive time when all external cues are removed. At first, he attempted to follow a routine. But as the weeks passed, his internal sense
