AI Thread Summary
The discussion focuses on seeking accessible resources for understanding the no boundary proposal in quantum cosmology, highlighting the difficulty in finding comprehensible explanations due to the model's technical nature. Participants mention the challenges of grasping the proposal without delving into complex texts like those by Hawking or Penrose. There is an interest in exploring criticisms of the model and its evolution over time, as well as the potential for experimental probes. A specific pedagogical note on quantum cosmology is shared as a helpful resource. Overall, the conversation emphasizes the need for clearer explanations in a field filled with unresolved mathematical issues.

Any good places to go to get a better layman understanding of the no boundary proposal other than Hawking books? Id like to see what criticisms there are of the model, how has it evolved over time and is there any chance for experimental probes of it.
 
Space news on Phys.org
Maybe Penrose's "The road to reality"? I also find it hard to find comprehensible outlines of the model, but I can see that about a lot of topics in quantum cosmology :P
 
Thanks Ill have a look at that, but that's not an easy book to follow either!
 
I've looked extensively for a decent explanation of it, but it remains hard because quantum cosmology is very technical and there are a lot of unresolved mathematical issues with it. I'm trying to sum it all up for myself, so if I have a decent conceptual understanding I'll come back ;)

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 'Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo".'

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...

Thread 'Big Bang and Infinite Universe'

Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
