I was thinking about the expansion of space. It seems clear that objects that are bound by gravitation or the strong nuclear force do not experience an increase in size as the universe continues it's expansion. However, such systems do contain abundant space. It is argued that gravitation and the strong nuclear force "overcome" the tendency of the space within their systems to expand. If so, would not these forces be minutely diminished by the process of "overcoming" expansion? Atoms and gravitationally bound systems are also flexible. Shouldn't the expansion of space within these structures be manifest by a release of energy as these flexible systems respond to the afore mentioned spatial dynamics?
