  After many fruitless decades of trying to unify electromagnetism and
gravitation, it is now being realized that this can be done only in discrete
spacetime, as indeed the author had demonstrated. In this context, a unified
description of gravitation and electromagnetism is provided within the
framework of a gauge like formulation. Following the discrete spacetime
structure, we then argue that the underpinning for the universe is an array of
Planck scale oscillators.
