Explanation:
The simple reason either a human or object can’t go to the centre of the Earth is extreme temperatures. Put basically, it is off-limits. Imagine we are descendiing down underground, so the first 6 mi (10 km) temperatures will reach 250°C (482°F). The next 30 miles down we will encounter partial molten rock with temperatures ranging from 650°C–1200°C (1200°F-2200°F). Next is the inner core, scientists esrimate the temperature to be 5,700°C (10,300°F). The farthest mankind has ever dug into the Earth, was by the Kola Superdeep Borehole which drilled 7.62 miles into the Earth. It was drilling from 1970 to 1989, and drill itself is only a few inches across but had to stop because of extreme temperature recorded at 180°C (356°F). The engineers said if it continued drilling deeper the drill would eventually cease to function as temperatures would continue to rise.
