I am desperately trying to remember the name of a book I read many years ago that had exactly the same thesis you are describing.
I know I read it, I recall many of the details, but the title and author are gone from my memory.
One of the more memorable points in the book [Starlight and Time] dealt w/ white holes - the opposite of black holes but no racism inferred/intended. I think the concept of white holes either originated w/ Einstein or was simply inspired by his works.
Another interesting aspect [I’ve seen other FR posts/links along the same line of thinking] regards time relativity and how much apparent time elapsed in the creation week. Consider assigning day 1 ~ 3.5 to 4 billion apparent years and then cut the apparent years in half for each subsequent day. At the end of the 1st week ~ 6 days you have 13.7 to 15.7 billion years of apparent time lapse.
Regarding predestination: God says and shows His awesome abilities declaring that He knows the Alpha [beginning] from the Omega [ending] which for me says he created time and only he knows what will happen before it occurs [shown multiple times w/ fulfilled biblical prophesies] ~
Therefore we have free-will but he knows every thought and action we will take before we do. Prayer is our chance to invite God to alter the outcome(s). Sometimes yes, no or often wait but should always be asked in accordance with ‘His Holy Will’ to allow for only our Father God knowing each eventual outcome and what will work best overall.
