Abstract

This dissertation critically reexamines two different alternatives to standard gravity.
In both cases, serious flaws in the methodology of previous work were found, raising
doubts as to the interpretation of results found by others. These issues are particularly
prominent in the context of perfect fluids, where the modifications introduce
additional complexity into the choice of an appropriate matter Lagrangian. In one
case, a large category of results is found to be physically meaningless; in the other a
many-order-of-magnitude improvement in limits is demonstrated.
