He that created the heavens, and stretched them out;
He that spread forth the earth, and that which cometh out of it; He that giveth breath unto the people upon it,
and spirit to them that walk therein:
Isaiah 42:5
"If you want to pinpoint your place in the universe, start with your cosmic address.
"If you want to pinpoint your place in the universe, start with your cosmic address.
You live on Earth->Solar System->Milky Way Galaxy->Local Cluster->Virgo Cluster->Virgo Supercluster->Laniakea.
Thanks to new deep sky surveys, astronomers now think all those places are part of an even bigger cosmic structure in the
"neighborhood" called The Shapley Concentration.
We already know that we "live" in Laniakea, which is about 500 million light-years across. However, the motions of other clusters indicate there's a larger "attractor" directing the cluster flow.
The Cosmic Flows data suggest that we could be part of the Shapley Concentration, which could be 10 times the volume of Laniakea. It's about half the volume of the largest structure in space, known as "the Great Wall," which is a string of galaxies stretching across 1.4 billion light-years. This discovery presents a challenge: our cosmic surveys may not yet be large enough to map the full extent of these immense basins."
