Dark energy does exist

"Dark energy" does exist, and it's not Albert Einstein's "greatest blunder" in his theory of gravity, say planetary scientists.

"Dark energy" is a concept first cast by Einstein in his original Theory of General Relativity. He included the idea in his original equations but later called it "his greatest blunder".

Now, a survey of 200,000 galaxies by a team, led by Dr Chris Blake of Swinburne University, has shown that "dark energy", responsible for expanding the universe, is real and not a mistake in Einstein's theory of gravity.

Using the Anglo-Australian Telescope, the team of 26 planetary scientists contributed to the "WiggleZ Dark Energy Survey" which mapped distribution of galaxies over a volume of the Universe.
