    Big bang Mass
Click For Summary
The discussion focuses on the mass and state of matter immediately after the Big Bang. It highlights the progression of matter from quarks to protons, neutrons, and eventually atoms as the universe cooled. Participants note the challenges in determining the mass of the universe at its inception due to the limitations of current physics. The conversation also touches on the conservation of energy in general relativity and its implications for cosmology. Ultimately, the exact mass of the universe right after the Big Bang remains largely unknown.

I've been looking for more information about the state of matter [or soon to be matter] shortly after the big bang. As time progressed after the big bang matter started to develop and it became more and more complex and massive [for the most part], we had quarks then protons then neutrons then atoms, etc... obviously this is an simplified history but the pattern is that as the universe cooled matter, for the most part, became more massive. So working backwards what can we say about the mass of the stuff right at or right after the big bang? I know that we don't know much about that time as our physics does really work well at that time, but can we say anything about the mass of the universe right at creation?

Are you asking about the state of matter, or the amount of matter? If it's the amount:

FAQ: How does conservation of energy work in general relativity, and how does this apply to cosmology? What is the total mass-energy of the universe?

When the universe became transparent after around 300,000 years I was told here that the entire universe looked like a diffuse, orange hydrogen gas.

Yeah, but he's asking about almost immediately after the BB. MANY orders of magnitude fewer time units than 300,000 years
 
Sorry. I was interpreting after the BB as meaning after inflation.
