Why have geologists not reached the mantle?
A
It is too hot for humans to go there.
B
It is too smelly for humans to go there.
C
It doesn’t have Wi-Fi so none of their instruments work.
D
Scientists have not figured out how to time travel.
Explanation: 

Detailed explanation-1: -Since the 1960s, researchers have attempted to drill into Earth’s mantle but have not yet met with success. Some efforts failed due to technical problems; others have fallen prey to various sorts of bad luck-including, as discovered after the fact, picking inopportune spots to drill.

Detailed explanation-2: -Humans have not been able to travel more than a few miles beneath Earth’s surface because of the intense heat and pressure. For the same reasons, humans have not been able to travel into the mantle. Temperatures in the mantle range from 1600 degrees Fahrenheit at the top to 4000 degrees Fahrenheit near the bottom.

Detailed explanation-3: -Short answer: No. On the large scale you can think of the Earth as a big ball of fluid. Withstanding the pressure of the bottom of the ocean is something that we are barely able to do, and that is only 0.2% of the way to the center of the Earth.

Detailed explanation-4: -Realistically, we will never get anywhere near the Earth’s core. The levels of heat, pressure and radioactivity (one of the main sources of internal heating) are so high that even if we could bore through over 6, 000km of rock and metal, a probe would be unable to survive.
