Physical implications of massless objects

Abstract

Normal massless objects have no mass but do have energy, and they always move at the speed of light. This article proposes another way to construct massless objects theoretically by combining normal mass and negative mass of equal magnitudes. Such objects have zero net mass, qualifying as massless, and can be used to investigate the behaviors of general massless objects. Particularly, two kinds of such proposed massless objects, neutral and electrically charged, are studied under the influences of gravity and electric fields. By excluding the factor of mass, it is discovered that the motion of electrically charged massless objects is counterintuitive. The physical implications of the motion of massless objects are analyzed in detail within the framework of classical physics. Some surprising results arise from these analyses, and possible explanations of these dilemmas lead to the possibility of a new relationship between electric charge and mass.
