This appears to contradict the theory of relativity, which predicts unequivocally that nothing can move through space faster than light. Because relativity has been incredibly successful at describing nature, with its many other predictions regularly being confirmed to extraordinary accurac...")

The intrinsic curvature of that geometry is what creates the gravity that we experience. This curvature in turn is made by energy (including mass), the movement of energy (including mass), and stress. Terminology: A given place and time together define an <i>event</i>. The separation of two events is described by an interval <i>s</i> that is a function of the coordinates (usual...")

The nucleus carries a strong positive charge; this charge attracts negatively charged but much lighter electrons. It is the electrons that participate in chemical bonds, so that the charge of the nucleus determines the chemical properties of the atom. Nuclei are made up of two kinds of particles – <i>protons</i> and <i>neutrons</i...")
