In a Rutherford α\alphaα-particle scattering experiment, a beam of α\alphaα-particles is directed at a thin metal foil in a vacuum. It is observed that the vast majority of the α\alphaα-particles pass straight through the foil with virtually no deflection.
Which of the following is the direct conclusion from this specific observation?
