I've always wondered how they know all that stuff, you know, what happened in the first second of the universe. I've read quite a few books on the subject and I've never seen any demonstration of how they know it.

Well, there are constraints from Big Bang Nucleosynthesis as well as signatures of inflation we see imprinted on the CMB.bobsmith76 said:I see evidence for the BB, which I already accept, I don't see evidence for how they know what happened in the first second.
Scientists use a combination of mathematical models, observations of the universe, and experiments to understand what happened in the first second after the Big Bang. They also rely on theories like the Big Bang Theory and the Standard Model of Particle Physics to make predictions about the events that occurred during this time.
There are several lines of evidence that support our understanding of the first second after the Big Bang. These include observations of the cosmic microwave background radiation, the abundance of light elements in the universe, and the behavior of particles in the Large Hadron Collider.
While we can never be 100% certain of what happened in the first second after the Big Bang, the evidence and theories we have allow us to make educated and accurate predictions about the events that occurred during this time. As technology and scientific understanding continue to advance, our understanding of the first second after the Big Bang may also improve.
Studying the events that occurred in the first second after the Big Bang gives us insight into the fundamental laws and processes that govern the universe. It also helps us understand how the universe has evolved and changed over time, and how it may continue to evolve in the future.
Yes, there are still many unanswered questions about the first second after the Big Bang. Some of these include the exact conditions and events that led to the Big Bang, as well as the nature of dark matter and dark energy, which are thought to make up a majority of the universe's mass and energy.
