Strongest Material

 

(1) A drawing of the tip of an atomic force microscope (AFM) pushing down on a graphene sheet-essentially a two-dimensional sheet of carbon atoms.

 

(2) A diagram showing the strengths and densities of various materials, with graphene off the chart at the top. MPa stands for mega-pascals, and here is essentially the amount of force needed to break the material.
