has definition Important physical principle and one of the basic laws of physics stating that matter is neither created nor destroyed (although mass may become energy, the energy quantitatively represents the mass). One exception to this principle is a singularity; another follows from the theory of virtual particles. | ![has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:33:56.0 has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:33:56.0](facet.gif) |
