Orion1 10 Posted July 20, 2020 Share Posted July 20, 2020 (edited) Astrophysicists unveil biggest-ever 3D map of Universe: The map is very isotropic and homogeneous, the large scale galactic filaments are not as apparent on this scale. Discussion? Isotropic: .(of an object or substance) having a physical property which has the same value when measured in different directions. .(of a property or phenomenon) not varying in magnitude according to the direction of measurement. Homogeneous: .of uniform structure or composition throughout.

Mordred 1372 Posted July 21, 2020 Share Posted July 21, 2020 Thanks for the link. Nice to see additional validation for the cosmological principle. Will study in more detail Link to post Share on other sites

I have located the official "Extended Baryon Oscillation Spectroscopic Survey (eBOSS)" website, listed in reference. The eBOSS team is using a universal time coordinate scale as the domain axis on their map, however, I am also interested in examining the CMBR photon surface of last scattering radial metric distance used on this map, the metric correspondence between space and time, called space-time. If anyone is able to cite a reference to that eBOSS CMBR radial metric data, please post a reference link. This is the YouTube "visualization of the data" video linked from their website: Reference: The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) website: https://www.sdss.org/surveys/eboss/ The full list of publications from eBOSS: https://ui.adsabs.harvard.edu/public-libraries/zjBkevkvQoCBUhWbnd38qg Edited July 22, 2020 by Orion1 text correction Link to post Share on other sites
