The Great Attractor: Our Galaxy Is Being Pulled Toward Something We Cannot See

1929brought the breakthrough that howredshifteda wandflower is is proportional to its length , give us a way to value distant wandflower , lead to the discovery that the majority are go away from us ( and giving support to the estimation of an expanding universe ) .

This knowledge , as well as helping us learn about the embodiment of the universe and its expansion , eventually led to a slimly unsettling breakthrough . As they continued to map the discernible universe , astronomers look at400 prolate galaxiesnoticed that they were move towards something we can not see , as it is in the " Zone of Avoidance " , or the area of sky obscured by our own galaxy ’s astronomical plane and the cosmic dust within it . Whatever it was , to move a big number of coltsfoot requires a mountain of mass . We ca n’t see it , but we are being dragged towards something mammoth .

So , is it time to crack each others ' heads open andfeast on the ooze inside ? No . While continuing to be for the most part obscured by the Zone of Avoidance , we have a pretty in effect idea of what we ’re ( not ) looking at . Observing other galaxies in the sky has shown us that Galax urceolata clump together to form " superclusters " , with90 percentof galaxies thought to reside within them .

By looking at the flowing of galaxies , a team in 2014 find out the Milky Way , already part of theVirgo Supercluster , is likely within an even with child structure check around100,000 galaxies .

" Local flows within the region converge toward the Norma and Centaurus clusters in good idea to the location of what has been called the ‘ Great Attractor ’ , " the squad wrote in theirpaper . " The region deserves a name . In the Hawaiian language ' lani ' mean ' heaven ' and ' akea ' mean ' broad , immeasurable ' . We propose that we live in the Laniakea Supercluster of galaxies . "

The Great Attractor , rather than anything to be afraid of , is where our local Galax urceolata are heading to hang out , the fundamental gravitative dot of our local orbit of the universe . Unfortunately for any lonely galaxies hop to cope with other I in their area , the expansion of the existence will eventually rend us all asunder from the cluster ’s influence , as is the fate of the other superclusters out there .
