"A new study says dark energy is real and is causing space-time and the universe to expand. ...
"The average distance between galaxy pairs is about 500,000,000 light years," says Dr Blake.

"Galaxies tend to grow on compression waves called baryon acoustic oscillations, which spread through the universe. They can be detected as ripples in cosmic microwave background radiation."

According to Dr Blake, "the average distance between these galaxy pairs has also been found to have grown because of the expansion of space-time, and that's further confirmation of an antigravity agent."

"We present precise measurements of the growth rate of cosmic structure for the redshift range 0.1 z 0.9, using redshift-space distortions in the galaxy power spectrum of the WiggleZ Dark Energy Survey. Our results, which have a precision of around 10% in four independent redshift bins, are well-fit by a flat LCDM cosmological model with matter density parameter Omega_m = 0.27."
