"The Deadly Consequences of Jumping Through the Earth's Core"

Digging a hole straight through the Earth is impossible due to the molten and liquid layers, but in a hypothetical scenario, jumping into such a hole would result in death from various factors. The first would be the extreme temperature, with the deepest humans have ever drilled reaching 180°C (356°F) at just 12 kilometers down. The second would be the massive increase in pressure, as the air would become highly pressurized and compressed. Additionally, if the pressure gets too high, it would likely evacuate all the air from the surface, killing most life forms. Finally, if the hole is not aligned with the Earth's axis of rotation, the rotational acceleration would cause the person to drift into the walls at high speed, resulting in injury or death.
