Imploder

Implosion occurs when external pressure significantly exceeds internal pressure, causing a structure or object to collapse inward rapidly.

In underwater environments, such as deep-sea diving or submarine operations, implosion is driven by immense hydrostatic pressure, which increases by approximately 1 atmosphere (101.3 kPa) for every 10 meters of depth.

For example, at 1,000 meters, the pressure is about 100 atmospheres, exerting enormous force on a vessel.

If the structural integrity of a submarine or sealed object fails—due to material fatigue, design flaws, or pressure exceeding the yield strength of the hull—water rushes in to equalize the pressure differential, causing catastrophic collapse.

The physics involves rapid compression of internal gases, often generating shockwaves and extreme heat from adiabatic compression.
