       Just a plot of all objects in the universe...

       @infobeautiful @socketwench This very cool plot sent me down a rabbit hole trying to find where it came from. A google reverse image search revealed that it was featured in a post by Jason Kottke (https://kottke.org/23/09/the-plot-of-all-objects-in-the-universe), which he references as having come from a 2023 article published in The American Journal of Physics by Charles H. Lineweaver andVihan M. Patel (https://doi.org/10.1119/5.0150209).I also found a similar plot (first attachment to this post) in the reverse image search results, which is from a lecture given by Joel R. Primack in 2012 at the University of California, Santa Cruz (http://physics.ucsc.edu/~joel/Phys5K/12Phys5K-Lect10-BlackHoles.pdf, page 11). He references an earlier 1984 lecture he presented in Varenna, Italy, which contains the second plot attached to my post (http://physics.ucsc.edu/~joel/Ay/233/Primack-VarennaLectures-slac-pub-3387.pdf, Figure 2.2, page 150). This fascinating plot of mass versus size has been around since Primack's early work on dark matter some 40 years ago.The new Lineweaver & Patel paper, which is unfortunately locked behind the usual science paywall, is accompanied by a short introductory video narrated by Lineweaver, which is enticing as a teaser and implies that there's some really interesting discussion to be read in the rest of the paper. It's a shame I can't dig further into this without forking over cash.Lineweaver & Patel cite Primack's earlier work, though oddly in the form of the popular science book "The View from the Center of the Universe", which he co-authored with his wife, Nancy Ellen Abrams, in 2006; the book version of the diagram is the third image attached. It's possible Primack used this diagram in one of his papers from the early 80s, perhaps "Formation of galaxies and large-scale structure with cold dark matter", published 1984 in Nature (https://www.nature.com/articles/311517a0). Alas, that's also stuck behind a paywall, so I can't dig through it.All in all, there's a lot going on in this mass versus size plot of everything, and it's a really thought-provoking way to view the universe.
