Special & General Relativity Questions and Answers
Could energy ever come to a point and create mass?
Well...that depends. Energy in the form of light, and in particular photons of light, can be stimulated to spontaneously produce matter/anti-matter pairs, but the photons have to pass by another particle in order to transfer angular momentum. Photons cannot individually create particles in empty space.
