AI Thread Summary
The discussion centers on the abundance of matter during the matter-antimatter annihilation phase, questioning the implications of a spatially flat and infinite universe on matter and energy. It is noted that in such a universe, the total amount of matter and energy would be infinite, raising questions about the significance of antimatter quantities. The concept of anti-energy is also explored, with the clarification that it does not exist as a counterpart to energy; annihilation of particles results in energy release rather than cancellation. The conversation highlights the complexity of defining the total energy of the universe and the lack of consensus among theorists on these topics. Overall, the discussion emphasizes the intricate relationship between matter, antimatter, and energy in cosmological theories.

Are there any explanations for the abundance of matter during the M/AM annhialation phase?

If the Universe is spatially flat and infinite, then would it have mattered how much Antimatter there was as by definition a flat and spatially infinite U has infinite matter and energy.

Is there also a measurable anti-energy? As if mass/energy are interchageable then wouldn't anti-matter be changeable with anti-energy?

Theorists always have answers to our questions. Just don't expect them to agree with each other :-)

WP has an article on this topic: http://en.wikipedia.org/wiki/Baryon_asymmetry

The total energy of the universe is not well defined: https://www.physicsforums.com/showthread.php?t=506985 I don't think there's even any standard way of saying whether it's finite or infinite.

There really isn't anti-energy. The difference between an electron and a positron is electric charge. For example, if you annihilate an electron with an antielectron, you get zero charge, but you don't get zero energy (energy canceling with anti-energy), you get 1022 keV of energy.
 
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...
