Dark Energy Is Real And Not An Einstein’s Blunder – Study

According to a result of a five-year survey of more than 200,000 galaxies that were up to 7 billion years old, dark energy is real and not a mistake in Einstein‘s theory of gravity, several international news sites reported on Friday.

According to a press release from Swinburne University of Technology in Melbourne, Australia, dated May 19, 2011, the finding is conveyed in two papers led by Dr. Chris Blake from Swinburne University‘s Centre for Astrophysics and Supercomputing.

Twenty-six astronomers contributed to the “WiggleZ Dark Energy Survey” which mapped the distribution of galaxies, using NASA‘s Galaxy Evolution Explorer telescope in space and the Anglo-Australian Telescope in Australia. According to reports, scientists found that dark energy appears to be a constant force, driving the cosmos apart at accelerating speed.

“The acceleration was a shocking  discovery, because it showed we have a lot more to learn about physics,” Dr. Blake was quoted saying. “Astronomers began to think that Einstein’s blunder wasn’t a blunder at all, and that the Universe really was filled with a new kind of energy that was causing it to expand at an increasing speed.”

“Although the exact physics required to explain dark energy still remains a mystery, knowing that dark energy exists has advanced astronomers’ understanding of the origin, evolution and fate of the Universe,” Professor Warrick Couch, Director of Swinburne’s Centre for Astrophysics and Supercomputing reportedly said.
