What is the strongest thing in the universe?

The strongest material in the universe may be the whimsically named "nuclear pasta." You can find this substance in the crust of neutron stars. This amazing material is super-dense, and is 10 billion times harder to break than steel.

What is the weakest thing on earth?

According to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure. When it comes to metals, scientists try to measure hardness in absolute terms.

Is Obsidian stronger than diamond?

Is Obsidian sharper than diamond? Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon's steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon's steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.

Can Obsidian cut through diamond?

Cutting edge At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge.

Are diamonds used to cut diamonds?

When diamonds are cut by hand, the technique is called bruiting -- cutting refers to bruiting by machine. When the cutter shapes diamonds by hand, he relies on the diamond's hardness as his tool -- he uses diamonds to cut diamonds.
