   For example, the as-received 203-micrometer (7.98-mil) fibers had an average tensile strength of 3.59 giganewtons per square meter (521 ksi) with a coefficient of variation of 23.5 percent.

   The following values have been calculated for femurs, in units of square metres per giganewton, where 1 giganewton = 10⁹ newtons, and with body mass given in tonnes, where 1 tonne = 10³ kilograms.

   If the fibres are all aligned in one direction, it is quite easy to achieve a modulus of 50 GN/m² and a tensile strength of 600 MN/m², although the shear modulus is at best only a few giganewtons per square metre.

   what does a giganewton do to an asteroid in the order of magnitude say 1/100 of a planet (otherwise it would have no impact at the planet).
