Scientists Finally Reached the Bottom of the Blue Hole… BIG Mistake

Underneath that, there's no oxygen, no life. And down there, we found conchs and conch shells and hermit crabs that had fallen into the hole and suffocated. 60 m down inside Biza's Great Blue Hole, the lights from the dive team cut through black water that feels almost solid. What should have been a peaceful descent turns heavier the closer they get to the seabed where oxygen disappears and silence takes over completely. And when they finally reach the bottom, it is not just sand waiting there, but a record of storms, decay, and time locked away for thousands of years.
