The Mysterious Dark Energy
  The concept of an all pervading Aether is age old, and contrary to popular belief, it survived the twentieth century too though with different nuances. Using this concept of a background Quantum Vacuum, the author in 1997 proposed a cosmological model with some resemblance to the Dirac cosmology, which correctly predicted a dark energy driven accelerating universer with a small cosmological constant, as was subsequently confirmed by observation in 1998. Moreover the so called Large Number coincidences including the mysterious Weinberg formula are deduced in this theory, rather than being ad hoc. We examine the concept of Aether in this context and indicate how this dark energy may be harnessed.
