  We describe the fission dynamics of $^{240}$Pu within an implementation of
the Density Functional Theory (DFT) extended to superfluid systems and
real-time dynamics. We demonstrate the critical role played by the pairing
correlations, which even though are not the driving force in this complex
dynamics, are providing the essential lubricant, without which the nuclear
shape evolution would come to a screeching halt. The evolution is found to be
much slower than previously expected in this fully non-adiabatic treatment of
nuclear dynamics, where there are no symmetry restrictions and all collective
degrees of freedom (CDOF) are allowed to participate in the dynamics.
