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.
Four years after the first synthesis of artificial diamond, cubic boron nitride c-BN was obtained and found to be the second hardest solid. [24] Synthetic diamond can exist as a single, continuous crystal or as small polycrystals interconnected through the grain boundaries. The inherent spatial separation of these subunits causes the formation ...

Astatine is a chemical element; it has symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth's crust, occurring only as the decay product of various heavier elements.
Osmium (from Ancient Greek ὀσμή (osmḗ) 'smell') is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element.
As in the cases of other refractory metals, the hardest known compounds of tantalum are nitrides and carbides. Tantalum carbide, TaC, like the more commonly used tungsten carbide, is a hard ceramic that is used in cutting tools. Tantalum(III) nitride is used as a thin film insulator in some microelectronic fabrication processes. [40]
The universe is permeated by a field known as the Higgs field, which gives everything its mass. But the Higgs field isn’t entirely stable, and if it were to “bubble,” it would change reality ...
A classical element referred to as the Fifth Element in ancient and medieval times. It is believed to be the material that fills the region of the universe beyond the terrestrial sphere. This belief goes as far back as Plato's Timaeus , where it is said that "there is the most translucent kind which is called by the name of aether (αἰθήρ)".
