Abstract
We discuss the relevance of the classical and quantum rolling tachyons inflation in the frame of the standard, pβadic and adelic minisuperspace quantum cosmology. The field theory of tachyon matter proposed by Sen in a zeroβdimensional version suggested by Kar leads to a model of a particle moving in a constant external field with quadratic damping. We calculate the exact quantum propagator of the model, as well as, the vacuum states and conditions necessary to construct an adelic generalization.

It is shown for the case of a conformally flat vacuum that the curvature of space-time may be viewed as the observable consequence of particle interactions involving a scalar field 4, rather than the independent agency of the gravitational field by itself. The quantum nature of gravity comes in as a
