Geologists cannot currently drill into the center of the Earth due to the extreme pressure present at that depth. The pressure at the center of the earth is estimated to be about 4 million times the pressure at the surface. This intense pressure would crush any drill bit or equipment attempting to penetrate the Earth's core. Additionally, the temperature at the center is estimated to be about 5,200 °C (9,392 °F), which is too hot for any known material to withstand.
