Dark matter is the thread connecting galaxy clusters

AI Thread Summary
Recent discussions highlight a new article confirming that dark matter acts as a connective thread between galaxy clusters. The findings align with previous expectations and contribute to the growing body of evidence supporting dark matter's role in cosmic structure. Additional resources on dark matter, including gravitational lensing and experimental techniques, reinforce these conclusions. Overall, the results further diminish the viability of alternative theories to dark matter. This ongoing research continues to deepen our understanding of the universe's composition.

I skimmed the article and it seems like a confirmation of what has been expected...a legitimate discussion. I believe such findings have been made by other teams but I am NOT current.

You can read some additional background on dark matter gravitational lensing and filaments here which is consistent with the discussion in your article:

and especially here which discusses different experimental techniques...

It looks pretty standard. The big thing about results like these is that they put more and more nails in the coffin of anything that isn't dark matter.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect...

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
