A new cosmological sceneario is proposed whereby superluminal expansion is invoked through the inherent instability of the early universe which results in a cosmic warp drive. In the evolution of our universe, after the inflationary phase, the expansion observed today sets in that is well described in terms of Friedmann equations. A smooth transition is expected between the two phases but string cosmology is known to have problems explaining this, our cosmic warp drive provides a novel solution to the graceful exit problem. Our proposed model addresses fine-tuning, the flatness problem, the initial conditions problem and the use of a new parametric oscillator that may mark the end of inflation instead of using a scalar field. We also take an elementary step towards the canonical treatment of strings removing the big-bang from the picture from cosmology. A more developed treatment of this theory in the future might completely remove big-bang from standard cosmology. Other implications of this model resulting from a possible solution to the graceful exit problem which might point to the values the fundamental constants are also discussed.
