Unveiling the Indestructible: The Toughest Substance in the Universe

While diamonds have long been considered the hardest substance, there are other contenders in the universe. Friedrich Mohs created a scale of hardness in 1812, with diamonds being assigned the highest value of 10. However, other measures of hardness, such as the Vickers hardness scale, have been introduced. Synthetic materials like graphene, wurtzite boron nitride, and lonsdaleite have been suggested to be harder than diamonds, but their hardness is still a topic of debate. Super-hard materials are sought after for industrial applications, but diamonds remain the go-to material for now.
