For the first time ever, experts researchers from the Hebrew University of Jerusalem have found that not only is our galaxy being PULLED, it also is being PUSHED by something. A new study recently published in Nature Astronomy describes a previously UNKNOWN, supermassive region in our extragalactic neighborhood largely empty of galaxies, which is exerting a REPELLING FORCE on our local group of galaxies.
Even though you may think you are still, you never are. Did you know that you are actually living on a planet that spins on its own axis, orbiting a star (our Sun) which is orbiting a galaxy which in turn is moving at mind-boggling speed? Even though you may not feel it, everything is in constant motion:
Our planet spins on its axis at about 1,600 km/h; it orbits around the sun at about 100,000 km/h; the sun orbits our Milky Way galaxy at about 850,000 km/h; and the Milky Way galaxy and its companion galaxy Andromeda are moving with respect to the expanding universe at roughly 2 million km/h (630 km per second).
But what is propelling the Milky Way’s race through space?
It turns out that there is a MYSTERY VOID which is literally pushing the Milky Way through the universe at a mind-bending speed of 1.2 Million miles per hour.
Previously, experts thought that our galaxy was speeding through the universe because it was being pulled to a specific, dense part of the universe due to that region’s gravity.
However, a new study has shown differently.
It turns out that the Milky Way is being swung across the universe by a so-called EXTRAGALACTIC VOID, in a process scientists call a kind of galactic tug-of-war.
While our galaxies journey through space has remained a mystery for decades, a new three-dimensional map has offered new insight into the mystery.
Previously, experts believed that a dense region of the universe was pulling our galaxy –toghether with neighboring galaxies—towards it which its gravity: believed to be equivalent to a gravitational force equivalent to a million billion suns.
The culprit: The Great Attractor, a region of clusters of galaxies 150 million light years from the Milky Way.
However, researchers from the Hebrew University of Jerusalem now say that not only is our galaxy being PULLED, it also is being PUSHED by something.
A new study recently published in Nature Astronomy describes a previously UNKNOWN, supermassive region in our extragalactic neighborhood largely empty of galaxies, which is exerting a REPELLING FORCE on our local group of galaxies.
Professor Yehuda Hoffman, lead author of the paper says: “By 3D mapping the flow of galaxies through space, we found that our Milky Way galaxy is speeding away from a large, previously unidentified region of low density.”
Furthermore, Professor Hoffman explains:
“Because it repels rather than attracts, we call this region the Dipole Repeller. In addition to being pulled towards the known Shapley Concentration, we are also being pushed away from the newly discovered Dipole Repeller. Thus it has become apparent that push and pull are of comparable importance at our location.”
With the aid of super-powerful telescopes, including the world-famous Hubble Space Telescope, researchers were able to create a 3D map of our universe.
The newly generated map helped experts identify the so-called Dipole Repeller, and researchers were able to reconcile both the direction of the Milky Way’s motion.
