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.

Thanks for the link. Nice to see additional validation for the cosmological principle. 

Will study in more detail

Affirmative. 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:

Very nice. Thank you. +1

Simply astounding, how insignificant we are.

"In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is uniformly isotropic and homogeneous when viewed on a large enough scale, since the forces are expected to act equally throughout the universe on a large scale, and should, therefore, produce no observable inequalities in the large-scale structuring over the course of evolution of the matter field that was initially laid down by the Big Bang." - Wikipedia
