Dark energy is the most mysterious fact in all of physical science, the fact with the greatest potential to rock the foundations. Read more:

The previous entry, 2012 Jun 04 – The world’s next big physics machine brought excerpts from an article about scientific developments and in this article I also found information about dark energy und here follow some excerpts:

 

When three American astronomers won the Nobel Prize in Physics last year, for discovering that the expansion of the universe was speeding up in defiance of cosmic gravity — as if change fell out of your pockets onto the ceiling — it reaffirmed dark energy, the glibly named culprit behind this behavior, as the great cosmic surprise and mystery of our time.
And it underscored the case, long urged by American astronomers, for a NASA mission to measure dark energy — to determine, for example, whether the cosmos would expand forever or whether, perhaps, there might be something wrong with our understanding of gravity.
In 2019, a spacecraft known as Euclid will begin such a mission to study dark energy. But it is being launched by the European Space Agency, not NASA

One of the hottest areas of research.

Dark energy is the most mysterious fact in all of physical science, the fact with the greatest potential to rock the foundations.
The discovery that the expansion of the cosmos was speeding up came from observing exploding stars known as Type 1A supernovas, luminous and uniform enough to serve as distance markers. Realizing that only a telescope in space could find and measure supernovas distant enough to shed light, so to speak, on the genesis of this behavior, Dr. Perlmutter early on urged the construction of a special space probe.
Two years ago, after a decade of wrangling among astronomers and NASA and the Energy Department, a blue-ribbon panel from the National Academy of Sciences charged with determining astronomical priorities endorsed a version of this idea as the highest-priority space science mission for the coming decade. The billion-dollar mission, called Wfirst, for Wide-Field Infrared Survey Telescope, would search for exoplanets as well as measure the effects of dark energy on the history and evolution of the universe.
