Query: Cosmic Acceleration from Varying Masses in Five Dimensions   Much effort has been made in trying to solve or at least evade the
inconsistencies that emerge from general relativity as the framework for a
cosmological model. The extradi- mensional models rise as superb possibilities
on this regard. In this work I present cosmo- logical solutions for Wesson's
Space-Time-Matter theory of gravity. A relation between mass variation at
cosmological scales and the expansion velocity of the universe is ob- tained.
Such a relation yields novel features on Space-Time-Matter theory of gravity,
which are carefully discussed.
