    A block of pure gold weighs about 110kg. Regardless of its size. This makes it the heaviest and the lightest material in the universe simultaneously.

      This is true.

      A cubic block of pure gold 12 light years across weighs 110 kg.

      A cubic block of pure gold 12 microns across weighs 110 kg.

        If my calculation is correct (and I always fuck those up) a cubic block with a side of 12 microns would have a volume of around 1.73x10^-15 cubic meters. The density of a neutron star is around 1x10^17 kg/m³ (according to quick google search). This would make the equivalent cube of neutron star “matter” around 173kg which would be slightly heavier than the gold.

        However, make the block of pure gold half its size, and as we all know it’s still 110kg.
