Eli5 – Why is it so difficult to dig to the Earth’s core?

447 views

The most central part of the Earth’s interior would require drilling approximately which is 6,370 kilometers (20,898,950 ft)

The deepest drilling ever conducted in world history is only 12 kilometers (39370,1 ft)

Why is so hard and and is the effort worth it? Or we only will find more rocks ?

Drilling horizontally for 6,400 km is completely beyond our current capabilities. The longest tunnels are less than 100 km, and they often have intermediate access shafts to the surface. And going down is much, much harder – you have to lift the excavated material back up, you have to stop the tunnel collapsing under ever-increasing sideways pressure, it gets hot enough to melt most materials, etc.
