Welcome to PF.

Can you post links to the reading you've been doing on this so far, and ask specific questions about that reading? Also, please give us an idea of your educational background -- you've marked this thread with an "I" prefix, which means that you'd like the discussion to be at the level of undergraduate university. Is that what you intended?
 
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...
what is the current status of the field for quantum cosmology, are there any observations that support any theory of quantum cosmology? is it just cosmology during the Planck era or does it extend past the Planck era. what are the leading candidates into research into quantum cosmology and which physics departments research it? how much respect does loop quantum cosmology has compared to string cosmology with actual cosmologists?
