Moreover, Morrison's novel questions rigid separatism as ultimately destructive of coalitions that depend
on forms of justice which remain grounded in inequitable power relations, particularly if the separatism functions on a patriarchal, hierarchical model; however, the text also explores the possibilities and even necessity of temporary forms of separatism in the formation of coalitions.
Nevertheless, as Boynton told SCIENCE NEWS, "We see an effect consistent with a fifth force that depends on composition.' The report also shows how the previous experiments, both positive and negative, can be made consistent with each other and with this one on the assumption that the fifth force acts in a certain way.
The best explanation seemed to be that another force was acting--a medium-range force that was repulsive but much weaker than ordinary gravity, and that depended on the nature of the substance involved, as ordinary gravity does not.
Fishbach's fifth force is a kind of negative gravity, a component of gravity that is repulsive for ordinary matter and that depends
on the nature of the substances involved, as ordinary gravity does not.
