Velikovsky's catastrophic theory of the Solar System is briefly reviewed. One of the most serious physical problems of his theory (i.e., that of determining a mechanism for disposing of tremendous orbital energies) is discussed. Specifically, gravitational interaction, electrical interaction and magnetic interaction are each considered, and found to be inadequate to dispose of the required amount of orbital energy. A modification to Velikovsky's theory is then proposed, which would permit gravitational interaction (electrical and magnetic interactions are still far too weak) to dispose of a far less amount of orbital energy, and still fulfill the appearance of what Velikovsky's theory proposes. Some theological aspects of Velikovsky's theory are discussed and it is pointed out that whenever the theory and Scripture truly disagree, the theory obviously must be modified. Analysis of such a theory are worthwhile means for developing analytical tools for handling other catastrophic theories.
