Query: Nonsingular Promises from Born-Infeld Gravity   Born-Infeld determinantal gravity formulated in Weitzenbock spacetime is
discussed in the context of Friedmann-Robertson-Walker (FRW) cosmologies. It is
shown how the standard model big bang singularity is absent in certain
spatially flat FRW spacetimes, where the high energy regime is characterized by
a de Sitter inflationary stage of geometrical character, i.e., without the
presence of the inflaton field. This taming of the initial singularity is also
achieved for some spatially curved FRW manifolds where the singularity is
replaced by a de Sitter stage or a big bounce of the scale factor depending on
certain combinations of free parameters appearing in the action. Unlike other
Born-Infeld-like theories in vogue, the one here presented is also capable of
deforming vacuum general relativistic solutions.
