(PhysOrg.com) -- An Australian-based astronomy team, co-led by Professor Michael Drinkwater from the School of Mathematics and Physics (SMP) at The University of Queensland (UQ), has shown that the mysterious 'dark energy' is indeed real and not a mistake in Einstein's theory of gravity.
Using the Anglo-Australian Telescope, 26 astronomers (from 14 different institutions) contributed to the ‘WiggleZ Dark Energy Survey', which mapped the distribution of galaxies over an unprecedented volume of the Universe.
Because light takes so long to reach Earth, it was the equivalent of looking seven billion years back in time – more than half way back to the Big Bang.

The survey, which covered more than 200,000 galaxies, took four years to complete and aimed to measure the properties of ‘dark energy' - a concept first cast by Einstein in his Theory of General Relativity.
