Scientists discovered that the milky way is moving with abnormally high velocity, exceeding the rate of expansion of the Universe, because great is pushed by an unknown force, according to a new study.
The researchers knew that the galaxy is moving at a relative speed in the last 30 years, but they didn't know why. "Now we see a void in the opposite direction, which provides a "push" in the sense of lack of traction," said Brent Tully, one of the authors of the study and an astronomer at the Institute of astronomy in Honolulu.
All of the moves. The earth rotates around its axis and around the Sun. The sun and the rest of our Solar system around the center of the milky Way. Milky Way along with other galaxies hurtling in space at a speed of about 2 million kilometers per hour. But that's not the aimless journey of the movement. "On average, galaxies are moving away from each other due to the expansion of the Universe," explained Tully. "Nevertheless, each one of them feels a gravitational tug from neighbors that cause deviant movement. To regions with high density and away from areas with low density of our Solar system is a tiny part of the galaxy we call the milky Way.
With the help of powerful telescopes, the researchers were able to create a 3-D map of the flow of the galaxy. Galaxies like our milky Way follow the distribution of matter, so they tend to move away from the sparse, empty regions in space. "We found a flow pattern resembling the flow of water, which are organised under the force of gravity to run down the hill," said Tully. Now, researchers believe that the milky Way is not just pull. It's as useful boost from the cosmic void behind the milky Way.
