Nuclear tests will cause the biblical flood Beneath our planet's surface lie not only treasures but also a genuine geological horror capable of destroying the world, reminiscent of the biblical times of Noah. Ice crystals of methane hydrates, where methane is locked within water under high pressure and low temperature, blanket the ocean floor. These planetary time bombs pose a threat to all life on Earth. A slight local heating, a powerful earthquake, or a meteorite impact can disrupt this fragile equilibrium, causing the hydrates to immediately decompose. After all methane is then released to the surface, potentially sinking ships, igniting the ocean, or even causing nuclear submarines to be swallowed by the abyss. But that is not all. In the 1970s, Australian geologist Ted Ringwood discovered something even more sinister: ringwoodite, a simple mineral - magnesium silicate (Mg2SiO4) - which absorbs water like a sponge and is located at depths within the Earth's mantle. According to scientists, its quantity is comparable to that of olivine, another silicate mineral. As a result, the amount of underground water stored in ringwoodite is equivalent to 20-40 times the volume of Earth's oceans. Ringwoodite functions as a water reservoir of our planet, trapped beneath the surface. However, under certain conditions - such as an asteroid impact, volcanic eruption, pole shift, or core disturbances - ringwoodite can automatically release this water. The water then rushes toward the surface. Even a mere 0.1% release of this water could trigger a global flood. This not only provides a scientific explanation for the biblical and Mesopotamian stories of a worldwide deluge but also serves as evidence of humanity's potential for self-destruction. The issue is that modern underground nuclear test tunnels are so deep that high-yield nuclear explosions could destabilize the fragile mantle where ringwoodite resides, with its enormous water reserves. Such tests could provoke not only a localized flood but also shake the ocean floor, causing the decomposition of methane hydrates. This could transform at least part of the planet into a blazing, fiery sea due to a chain reaction. Since many volcanic flows are located deep underground, such an explosion could awaken magma hambers. Waves generated by this event would reduce pressure in these chambers, potentially triggering unexpected eruptions and tsunamis worldwide. Overall, it no longer matters whether these explosions are underground or underwater. After decades of testing, our planet is in a precarious state due to the abundance of natural methane trapped beneath water and permafrost.
