Hello.
I'm trying to obtain a better understanding of the earliest epochs of the universe's evolution and have been looking here...
https://www.physicsoftheuniverse.com/topics_bigbang_timeline.htmlhttps://en.wikipedia.org/wiki/Chronology_of_the_universehttp://www.astro.ucla.edu/~wright/BBhistory.htmlhttps://sites.uni.edu/morgans/astro/course/Notes/section3/bigbang.html
Now to my questions.
1.
Am I correct in thinking that all the listed information in these timelines about epochs prior to Recombination is based upon inference and extrapolation, rather than direct observation?
2.
Hawking and Penrose's seminal paper on singularity theory, "The Singularities of Gravitational Collapse and Cosmology' https://royalsocietypublishing.org/doi/pdf/10.1098/rspa.1970.0021, if still applicable, would apply to which epoch/s of the very early universe?
3.
mfb has kindly pointed me to these links... https://en.wikipedia.org/wiki/Big_Bang_Observer and https://arxiv.org/abs/1808.01892
My last question is therefore this. Would gravitational waves and/or neutrinos be able to probe back to the epoch/s that the Hawking - Penrose singularity theorems were designed to describe?
Many thanks in advance for any help given. Please note that my level of competence in PF is 'Basic' and I would therefore appreciate any replies being pitched at that level, please.
Thank you.
Cerenkov.
