I seem to have missed the opportunity to post my questions on a related thread so I hope this is okay. First, a request. I have read on this forum that ["Singularity" is just shorthand for "the place where the math model breaks down and we don't know WHAT is/was happening".]. Since the wiki doesn't have a lot of info on this matter, are there any respected sources to back this claim up? I also have 2 questions: 1)Does the Big Bang singularity require space-time or space/time to exist? Does it require anything at all to exist or can it be an independent entity on its own? 2)Can it be said that the singularity is the Universe in another form? If so, can we say that the Universe is eternal? Do we have any reason to suspect( in the models that point towards a singularity) that the said singularity did not exist eternally into the past? I know the second question is not framed right since as far as I know in the models that have the initial singularity, time does not exist prior to the Big Bang expansion but I hope you get my point.
