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 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.

Thread 'Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out)'

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
