You read it here first. Maybe.

cutting edge science, awesome presentation

I'm going to write that on a card and put it in my pocket so if I should forget, whoever finds me will know where I belong.

(40,367 posts)it's always good to plan ahead.
That video details some remarkable research, G_j. In less than a century, humanity has seen the size of the cosmos grow from the 100,000 light year-wide Milky Way to the 13.8 billion light year-wide universe with clusters and superclusters and who-knows what else.
Seeing the filaments connecting clusters and superclusters shows how, even on cosmic scales, we are attached to one another in ways that we're just starting to learn. To see the "side filaments" curling up and away, while rudimentary today, gives us an understanding of the true nature of reality that seemed impossible when we were kids.

I love astronomy. I'm at home anywhere there's a sky.

When I saw that, I immediately thought of a giant brain.

(2,252 posts)...A video map of motions in the nearby universe
The presentation is a bit more dry than the introduction of the Laniakea Supercluster, but it presents the data more completely and highlights the kind of analysis done to locate the Milky Way's place in the grander scheme.
The 17 minute video is worth watching. It's Vimeo, and I couldn't get a url to embed the video here.
An international team of researchers, including University of Hawaii at Manoa astronomer Brent Tully, has mapped the motions of structures of the nearby universe in greater detail than ever before. The maps are presented as a video, which provides a dynamic three-dimensional representation of the universe through the use of rotation, panning, and zooming. The video was announced last week at the conference "Cosmic Flows: Observations and Simulations" in Marseille, France, that honored the career and 70th birthday of Tully.
The Cosmic Flows project has mapped visible and dark matter densities around our Milky Way galaxy up to a distance of 300 million light-years.
The team includes Helene Courtois, associate professor at the University of Lyon, France, and associate researcher at the Institute for Astronomy (IfA), University of Hawaii (UH) at Manoa, USA; Daniel Pomarede, Institute of Research on Fundamental Laws of the Universe, CEA/Saclay, France; Brent Tully, IfA, UH Manoa; and Yehuda Hoffman, Racah Institute of Physics, University of Jerusalem,
The large-scale structure of the universe is a complex web of clusters, filaments, and voids. Large voidsrelatively empty spacesare bounded by filaments that form superclusters of galaxies, the largest structures in the universe. Our Milky Way galaxy lies in a supercluster of 100,000 galaxies.
