An Australian-based astronomy team, co-led by Professor Michael Drinkwater from the School of Mathematics and Physics at the University of Queensland, 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 â€˜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 â€“ more than half way back to the Big Bang.
â€œThis is the first individual galaxy survey to span such a long stretch of cosmic time,â€ said Professor Drinkwater said.
"It was only possible thanks to new Australian technology.â€
