Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
If it exists, nuclear pasta would be the strongest material in the universe. [1] Between the surface of a neutron star and the quark–gluon plasma at the core, at matter densities of 10 14 g/cm 3 , nuclear attraction and Coulomb repulsion forces are of comparable magnitude.
Diamond was the hardest known naturally occurring mineral when the scale was designed, and defines the top of the scale, arbitrarily set at 10. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, or the softest material that can scratch the given material.

The precise tensile strength of bulk diamond is little known; however, compressive strength up to 60 GPa has been observed, and it could be as high as 90–100 GPa in the form of micro/nanometer-sized wires or needles (~ 100–300 nm in diameter, micrometers long), with a corresponding maximum tensile elastic strain in excess of 9%.
The fragments then formed Bennu and other "rubble pile" asteroids - loose amalgamations of rocky material rather than solid objects. Early in its history, some of the ice inside the parent body ...
The lower oxidation states are stabilized by the larger halogens, so that the trichloride, tribromide, triiodide, and even diiodide are known. The oxidation state +1 is known only for osmium monoiodide (OsI), whereas several carbonyl complexes of osmium, such as triosmium dodecacarbonyl (Os 3 (CO) 12), represent oxidation state 0.
