The 2011 Nobel Prize in Physics recognized the discovery made 1998 about observational data indicating that space expands at an accelerating rate. The generally accepted interpretation has been that the intergalactic gravitational force is counteracted by a stronger force with an unknown source. It is called Dark Energy and stated to dominate in the Universe. Nobody has come up with a generally accepted explanation about its nature. However, an attempt was made to apply a new cosmic perspective in an article published 2009 by the Swedish Mathematical Society. It is based on the Wave Theory of Time, WTT.

A close description of the observed accelerating expansion of space is provided by the Cosmologial Constant. WTT explains the estimated magnitude as dependent on the presently applied reference of time and makes the numerical value equal to zero if time is measured with a natural reference. For comparison, the Sun and not Earth is in space a natural reference for calculating planetary trajectories. The shift of reference changes the accelerated rate of the cosmic expansion from a positive to a negative value. WTT has simply no need of any Dark Energy assumptions. A challenge to discuss the matter was in vain published twice 2012 by the Swedish Mathematical Society. 

The explanation offered by WTT is still completely ignored by the expertise. However, plenty has been written about other proposals for explaining Dark Energy. In summary, assumptions have been made about an intrinsic property of space as described by the Cosmological Constant in the equations of General Relativity, about space as full of temporary particles permitted by the quantum theory or of a "quintessence" fluid with an effect opposite to that of matter and normal energy, and about a possible error in the presently used theory of gravity.  

In the not too remote future, cosmologists are likely to recognize as the greatest blunder in the history of science that some kind of mysterious Dark Energy was once commonly believed to dominate in the Universe.
