The Mariana Trench, plunging nearly 11 kilometers beneath the Pacific Ocean, is the deepest known point on Earth’s seabed. Its most profound section, the Challenger Deep, is so remote and extreme that it would take over an hour for a small stone to reach the bottom due to the immense depth and resistance of water. Terminal velocity in water for an object like a stone is around 5 to 6 meters per second, but drag and current variations make the descent much slower than expected. To put this in perspective, the trench is deeper than Mount Everest is tall. Pressure at the bottom exceeds 1,000 times the atmospheric pressure at sea level, enough to crush most submarines without reinforced hulls. Only a handful of crewed missions have ever descended to the floor, including dives by James Cameron and Victor Vescovo. The Mariana Trench remains one of Earth's most mysterious frontiers, hiding unknown lifeforms and geological secrets yet to be uncovered. #MarianaTrench #OceanDepths #DeepSeaExploration #EarthsExtremes #ScienceFacts

In a groundbreaking 2005 experiment at Yale, researchers taught capuchin monkeys how to use tokens like currency—revealing surprising insights into primate economics. The monkeys learned to exchange tokens for food, showing behaviors like budgeting, risk-taking, and even gambling. But in one unplanned twist, a monkey exchanged a token for mating—a moment that sparked headlines worldwide. While isolated, it hinted at how quickly learned behaviors can extend into unexpected territory. This study revealed that economic instincts may run deeper in evolution than we ever imagined. #MonkeyEconomics #BehavioralScience #AnimalIntelligence #YaleStudy #CapuchinMonkeys #ScienceFacts
