B From where is the universe expanding?

Click For Summary
The universe is expanding uniformly, with no defined center or edges. This expansion is characterized by an intrinsic increase in distances between objects rather than a movement from a specific point. The concept of a stable center is dismissed, as the universe's expansion is ongoing and dynamic. Additional insights on this topic can be found in the linked resource discussing the Friedmann equation. Understanding these principles is crucial for grasping the nature of cosmic expansion.

Is it expanding from the edges?
Or from the center?
 
Space news on Phys.org
As far as we can tell there is no center nor any edges. The expansion is an intrinsic increase in distances between objects.

At all? Or not stable because of the constant expansion of it?
 
At all.

Thread 'Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo"'

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
