@nielsnielsen For the book of Smolin "Time reborn" see his presentation and talk youtube.com/watch?v=ATxi0_-7HqQ– Jo WehlerCommented Oct 25, 2023 at 18:06

Do you have an opinion on the trustworthiness of Smolin's conclusions? I found Time Reborn useful but lack the expertise to properly judge or recommend it.– g sCommented Oct 25, 2023 at 19:42

@8Mad0Manc8: Oh, it's even worse than that. Your entire premise is bunk, as there are models of reality, particularly conformal cyclic models, where there is no earliest time. Instead, what we perceive as the beginning of time is merely the beginning of the current inflationary regime within our locally observable universe. The universe could be expanding forever, without beginning or end, giving rise to physics as energy self-interacts across expanding spacetime.– CorbinCommented Oct 26, 2023 at 18:51

Yes Roger Penrose (I think) proposed that but simply put it is the proposition that time does have a beginning and it also does not have a beginning. However, I point you to temporal finitism, and the proposition that If time had no beginning how do we get to the present by succesive addition from an infinite past.– 8Mad0Manc8Commented Oct 26, 2023 at 20:47

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. philosophy-of-science), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
