What is the densest material on Earth?

The densest material on earth was created by the Large Hadron Collider and named quark-gluon plasma. The substance can only exist in extremely hot temperatures and is denser than a neutron star.

Scientists first created quark-glucon plasma in February 2010 by colliding gold and lead ions with each other at speeds nearing the speed of light. The result was a plasma so dense that just 1 cubic centimeter weighs over 40 billion tons. This state of matter only exists in temperatures above 4 trillion degrees Celsius. Scientists theorize that the universe was filled with quark-glucon plasma one-trillionth of a second after the big bang.
