Suppose that a gluon, which holds the nucleus of an atom together, can travel across the nucleus at 1% of the speed of light or 3 × 108 cm/s and that the average binding energy of a gluon is 4 GeV. According to the uncertainty principle, how long can it bind together a proton and a neutron before it must disintegrate back into the vacuum?
