Ever Wondered Why Does The Inner Core Of The Earth Never Melt?

The longstanding mystery about earth's core has been resolved.


"Not only land but we have been to the depths of heaving seas,

Upon our steed of zeal, we rode unto their darkest boundaries'' - Allama Iqbal

We, humans, have literally explored almost every corner of the earth. We have conquered the toughest of terrains and have been to the base of deepest of oceans, but we have never been to the earth's core.

What all lies below the earth's crust is wrapped up in mystery, and yet we know quite a lot about our planet's core. Isn't this strange?
