AI Thread Summary
The discussion centers on the status of the Japanese Miniature Universe Experiment, initiated by scientists in 2006, which explores the concept of creating a miniature universe based on Smolin's cosmic natural selection hypothesis. Participants seek updates on the experiment's current progress and relevant literature. Key papers by Sakai and collaborators are referenced, indicating ongoing research in this area. The original article and additional resources are provided for further reading. The experiment remains a topic of interest in the scientific community.

Recently I read an article about Japanese scientists trying to create a miniature universe. The article was pretty old, 2006. Does anyone know the status of this experiment, or know where i can read more of their present progress?

The idea is related to Smolin's cosmic natural selection hypothesis. I presume the paper you are referring to is

The universe out of a monopole in the laboratory?
http://arxiv.org/abs/gr-qc/0602084
by Sakai, et al.

He has collaborated on these papers since
arXiv:0712.1450
arXiv:0803.0268
arXiv:0805.3446
arXiv:1005.4250
 
Awesome thank you
 
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##.
Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
