SUMMARY

The forum discussion centers on the understanding of the Big Bang timeline, particularly the epochs prior to Recombination. Participants clarify that the information regarding these early epochs is based on observations, such as the abundances of light elements from Big Bang Nucleosynthesis, rather than mere inference. The applicability of Hawking and Penrose's singularity theorems to the early universe is debated, concluding that these theorems do not apply due to the idealized models they are based on. The discussion emphasizes the distinction between mathematical and physical theorems in cosmology.

PREREQUISITES
  • Understanding of Big Bang Nucleosynthesis
  • Familiarity with Hawking and Penrose's singularity theorems
  • Knowledge of the Epoch of Recombination
  • Basic principles of cosmology and observational evidence
NEXT STEPS
  • Research the implications of Big Bang Nucleosynthesis on cosmic element formation
  • Study the differences between mathematical and physical theorems in cosmology
  • Explore the role of gravitational waves in probing early universe epochs
  • Investigate the current theories surrounding the inflation epoch and its implications
USEFUL FOR

Astrophysicists, cosmologists, students of physics, and anyone interested in the early universe and the foundations of cosmological theories.

It looks like I may well have further questions about the SEC. If that's so, then should I post them here, as a continuation of this thread, or begin a new one?

Please start a new thread. If it's a general question about energy conditions, not particular to cosmology, it should probably be in the relativity forum instead of this one. For example, questions arising from the paper you linked to would fall into this category.

Whew! Gentlemen, thank you... that helped. For a minute there I was beginning to imagine giant caterpillars smoking hookas might be real ;)
They ARE real. Just not in our universe :smile:

Thank you for the advice Peter. I'll do just that.

Cheers.
