AI Thread Summary
The discussion centers on a hypothesis suggesting that anomalous ionization near galactic centers is caused by dark matter particles colliding to create electron-positron pairs, potentially leading to detectable gamma rays. Participants inquire about relevant research papers, with links provided to both a published paper and a free version. There is a consensus on the need for further investigation to determine if the hypothesis holds true. The conversation emphasizes the significance of next-generation telescopes in confirming these findings. Overall, the exploration of dark matter's role in cosmic phenomena continues to generate interest and debate.

The hypothesis is that the anomalous ionization noticed near galactic centers is due to dark matter particles colliding to make an electron and positron. This would produce distinctive gamma rays detectable by the next generation of telescopes.

 
Space news on Phys.org
Is there a link to a paper somewhere in that video?
 
Ok - too much particle physics in that for me.

I guess we'll see if it pans out.

Thread 'Illuminating Black Hole Shadows with Dark Matter Annihilation'

Abstract The Event Horizon Telescope (EHT) has significantly advanced our ability to study black holes, achieving unprecedented spatial resolution and revealing horizon-scale structures. Notably, these observations feature a distinctive dark shadow—primarily arising from faint jet emissions—surrounded by a bright photon ring. Anticipated upgrades of the EHT promise substantial improvements in dynamic range, enabling deeper exploration of low-background regions, particularly the inner shadow...

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'If the Universe has a cause, what caused that cause?'

Title: Can something exist without a cause? If the universe has a cause, what caused that cause? Post Content: Many theories suggest that everything must have a cause, but if that's true, then what caused the first cause? Does something need a cause to exist, or is it possible for existence to be uncaused? I’m exploring this from both a scientific and philosophical perspective and would love to hear insights from physics, cosmology, and philosophy. Are there any theories that explain this?
