Observe the flow of dark matter, the farthest in the universe

American astronomers on March 17 announced that they have observed the darkest, most moving mass of matter in the universe ever.

According to Alexander Kashlinsky, research leader at the Goddart Space Flight Center of the US Aeronautics and Space Administration (NASA), his team observed the motion of 1,500 galactic beams and the size of microwave background radiation. The universe (CMB), obtained by telescopes on the universe and at the ground for the past 5 years.

The results show that this dark matter stream, moving at an extraordinary speed of over 1.6 million km / h in the direction of stellar Centaurus and Hydra and 2.5 billion light-years from Earth, is about twice as far measured in previous studies and the longest distance that humans can observe in the universe ever.

Scientists claim that the motion of these galactic beams cannot be explained by any known cosmic force. However, the results of this study reinforce the hypothesis that dark matter streams are real.

Scientist Kashlinsky and his colleagues first published the size of dark matter flow in 2008. They noted signs of the unusual movement of these galactic beams due to the light left over from Big Bang explosion, created the universe 13.7 billion years ago. This leftover light is called CMB.

This whole new study is published in detail in the Journal of Astrophysics on March 20.
