The galactic plane was achieved by scanning through a spectroscope that traced the sound tracks of the Big Bang.
A group of astronomers announced the most accurate results (so far ) of the expansion of the universe and dark matter. As reported in the portal IFL Science, hundreds of scientists from around the world helped create a map in 3 dimensions of the cosmos and its millions of galaxies.
The sound of creation. the project called Baryon oscillation Spectroscopic Survey (BOSS) uses the distribution of galaxies in the universe to estimate the size of the baryon acoustic oscillations, which are sound waves that swept the early universe and appeared after the sudden cluster mass was in the process leading to the formation of the first galaxies.
Proportions. it is estimated that there are about 100 billion galaxies in the universe, however the map only it covers 1.2 million and its three dimensions comprising a width of 6 billion light years from 4.5 million light years tall and 500 million deep. In this universal atlas we can see the giant dimensions of the universe. However also appear fuzzy or gray tones which scientists do not yet have data sections.
constant expansion. But one of the discoveries that most surprised the scientists was that the map can observe how the universe is continuously and increasingly fast expanding. This is caused by a dark energy, as mentioned in the theory of relativity, which acts as a counterforce to gravity and causes the acceleration.
universal mapping. the map could be done with the help of automated Sloan Digital Sky Survey, which allowed specialists collect data from 1.2 million galaxies. “We have spent a decade gathering this information and thanks to this map we could get the best results on the effects of dark matter in the expanding universe,” said Jeremy Tinker University of New York and head of the project.
