SUMMARY

The discussion centers on the Big Bang Theory (BBT) and its supporting evidence, as well as the emerging concept of the Big Bounce. Key resources provided include links to articles on Big Bang Nucleosynthesis, the history of the Big Bang Theory, and evidence supporting the BBT. The conversation emphasizes the importance of understanding the theory and encourages the sharing of additional resources. The BBT is recognized as the prevailing cosmological model, while the Big Bounce is introduced as a topic for future exploration.

PREREQUISITES
  • Understanding of Big Bang Nucleosynthesis
  • Familiarity with the history of the Big Bang Theory
  • Knowledge of cosmological evidence supporting the Big Bang
  • Awareness of alternative cosmological models, such as the Big Bounce
NEXT STEPS
  • Research Big Bang Nucleosynthesis through the provided UCLA link
  • Explore the history of the Big Bang Theory via the Suite101 article
  • Investigate the concept of the Big Bounce and its implications for cosmology
  • Review the Frequently Asked Questions in Cosmology for a deeper understanding of mainstream theories
USEFUL FOR

Astronomers, cosmologists, students of physics, and anyone interested in understanding the foundational theories of the universe's origin and the ongoing discussions in modern cosmology.

Hello All

Reading many posts I find people not understanding the theory behind the Big Bang.

I do not agree with the BBT, but! that does not make me right. I'm not emotionally attached to any theory.

Here are some links in support of the Big Bang, later I will post against. For now maybe discuss the supporting issues.

Tango at your speed.

If anybody has links that can support the Big Bang, please post them.

Space news on Phys.org
Space-time inflated then matter came later and fell together. And by this then radiated. This way of creating matter with finite density allows the Big Bang to get over its limiting infinite gravity.

Space first then matter then radiation to go Bang!

What do you have about the Big Bounce? Lately I don't hear so much talk about big "bang" and "singularity". Instead i hear about the proposed cosmological bounce.

This proposal goes back in time a little before where the old singularity was supposed to be.

Do you have any links about the Bounce? do you have some explanation or support links?
Please add them to your list!
