Starting with Einstein's theory of special relativity and the principle thatwhenever a celestial body or an elementary particle, subjected only to thefundamental forces of nature, undergoes a change in its kinetic energy then themass-energy equivalent of that kinetic energy must be subtracted from therest-mass of the body or particle, we derive explicit equations of motion fortwo falling bodies. In the resulting mathematical theory we find that there areno singularities and consequently no blackholes.
