Distribution and proportion of dark matter in galaxies

AI Thread Summary
The distribution and proportion of dark matter in galaxies varies significantly between regular-size galaxies and dwarf galaxies. Current theories suggest that dark matter may constitute up to 99% of the universe, although some estimates place it at around 96%. There is ongoing uncertainty regarding the exact relationship between dark matter and regular matter, as well as how gravity operates on larger cosmic scales. This lack of clarity highlights the limitations of current theories in accurately describing dark matter's role in the universe. Understanding dark matter remains a critical area of research in astrophysics.

I read that the distribution and proportion of dark matter to regular matter is different for regular-size galaxies and dwarf galaxies. Could you guys elaborate on that?
 
Astronomy news on Phys.org
the theory is that dark matter could cover 99 percent of our universe, but today i don't think we know much about it relative to regular matter.
 
I thought it covered 96%
 
It could be a lot less depending on how innaccurate our theories are.

We don't really know for sure how gravity works on larger scales.

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...
