What do we know about Baryogenesis?

AI Thread Summary
Baryogenesis is a process that occurred shortly after the Big Bang, leading to an imbalance between matter and antimatter, allowing quarks to dominate. Current understanding highlights CP asymmetry due to the Weak Force as a contributing factor, but it may not fully explain the observed imbalance. The knowledge of baryogenesis is relatively advanced compared to other cosmological areas, with significant contributions from particle physicists and strong experimental support. While predictions about primordial element abundances are largely accurate, some discrepancies remain regarding heavier elements. Overall, baryogenesis presents a compelling mystery that could enhance the narrative of a game centered on high-energy particle physics.

I'm part of a games studio who is currently building a game about high energy particle physics (essentially you control a quark and have to try not to get annihilated by anti-quarks), and we're thinking of setting it just after the Big Bang.

One idea we've been toying with is that you're essentially playing out the conflict between particles and antiparticles, and that you possibly play in a part in baryogenesis (the process that allowed the quarks to 'win').

As far as I can tell, baryogenesis is still pretty vague. We know that there's CP asymmetry between particles and antiparticles due to the Weak Force, and that this could lead to the imbalance, but from what I've read, the CP violation isn't really enough to cause the imbalance observed.

If this is the case, it's a really nice juicy mystery that we could approach in the game. If not, I'm hoping we can utilise whatever else is out there.

So my question is: what else, if anything, has been found out about baryogenesis?

I see negative effects on the physics knowledge of players.

That would require the own annihilation, as every other process involving particle changes. A very common process in the early universe anyway.

It happened, and it requires high energy. And, well... some other stuff.
As usual, Wikipedia gives an introduction.
 
Actually, our knowledge of baryogenesis is rather advanced compared to other areas of cosmology. Much of this knowledge was contributed by particle physicists and has good experimental support. We have predicted primordial abundances of the elements with great accuracy. There remain a few quibbles over the relative abundance of some of the heavier elements [e.g., deuterium, lithium], but, the predictions are generally very good. We also have extensive knowledge of the energies required to produce most of the fundamental particles.
 
@Chronos: Baryogenesis happened before the formation of nuclei via fusion. The second process is well understood, the first one is not (at least not as good as other processes).
 
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...
