AI Thread Summary
The discussion explores the nature of atomic structure and whether it is an inevitable outcome of the Big Bang or if alternative forms of matter could have emerged. It highlights that no structural information could be transmitted through the Big Bang, leading to philosophical implications regarding the existence of atoms. The anthropic principle suggests that atoms exist in their current form because they support life, allowing for observation. The concept of a multiverse is introduced, where different fundamental constants could lead to vastly different physical realities, with most being unable to form complex structures. Ultimately, atoms form when temperatures drop sufficiently, consuming a significant portion of early universe mass.

Is their structure so "great" that they are just a natural, or inevitable, outcome of the mass/energy burst that took place or, within our knowledge base now, would some other form(s) of minute size matter been just as good or better? It is known that no information, say like structure plans, could be "passed" through the Big Bang event.

This is bordering on philosophy! I guess you could use the anthropic principle here and say the only reason we observe atoms the way they are is because they are supportive for life to evolve, so that someone can observe them. If the electron charge and proton charge were different for example, then atoms would be very different (if even at all possible) to the ones we see now. Some physicists (string theorists and some cosmologists) have proposed that a multiverse exists, where each Universe has different fundamental constants. In the vast majority of these Universes, the physics is so bizarre that the Universes are not very interesting and cannot form structures. We could just so happen to be a Universe where things are nicely balanced to give rise to atoms, and hence structure and hence life...
 
Confusing. Atoms form when the temperature drops below the level necessary to knock an electron out of a hydrogen atom. It's that simple. That process consumes about 3/4's of the mass of particles in the early universe.

Particles other than atoms exist.
 
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##.
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...
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...
