Can String Theory Explain Dark Energy?
A new paper by Cambridge physicist Stephen Hawking and Thomas Hertog of CERN (email@example.com) suggests that it can. The leading explanation for the observed acceleration of the expansion of the universe is that a substance, dark energy, fills the vacuum and produces a uniform repulsive force between any two points in space -- a sort of anti-gravity. Quantum field theory allows for the existence of such a universal tendency. Unfortunately, its prediction for the value of the density of dark energy (a parameter referred to as the cosmological constant) is some 120 orders of magnitude larger than the observed value.

Neither do I accept that the world you speak of is none existanent but its not the whole truth.
