A galactic census taken of 200,000 galaxies possibly confirmed the theory of dark energy forces which are pulling the universe apart at increasing speeds.
The five-year may have provided support to the dark energy theory and may have brought about contradictions to many others. One theory it brought contradictions to is Albert Einstein’s concept of gravity. The information gathered from the census shows dark energy acting as a repulsive force rather than an attractive one.
Some may be wondering what exactly is dark energy? Chris Blake of Swinburne University of Technology in Melbourne, Australia explained it like this, “The action of dark energy is as if you threw a ball up in the air, and it kept speeding upward into the sky faster and faster. He then talks about the some of the results, “The results tell us that dark energy is a cosmological constant, as Einstein proposed. If gravity were the culprit, then we wouldn’t be seeing these constant effects of dark energy throughout time.”
Astronomers used galaxy maps to study the clusters of galaxies and determine how much they attract and repulse over time. The gravitational pull of the clusters attracts new galaxies, but dark energy appears to tug them apart, and scientists are able to measure dark energy’s repulsive force. Jon Morse, director of the astrophysics division at NASA headquarters in Washington, D.C. had this to say;
“Observations by astronomers over the last 15 years have produced one of the most startling discoveries in physical science: The expansion of the universe, triggered by the Big Bang, is speeding up. Using entirely independent methods, data from the Galaxy Evolution Explorer have helped increase our confidence in the existence of dark energy.”Stay Connected
