Main Question or Discussion Point
Is there any possibility of coming up with physical measurements that will ever tell us any thing about the universe before the big bang? I can not think of any.
I don't know the answer to that, Phil. Only a handful of papers have been written so far that study how LQG bounce relates to inflation. I will list some recent ones---because even if you just look at the summary at the beginning, and the conclusions at the end (skipping the technical detail) you can get some idea of where things stand and what they are saying.MArcus, do you know if the inflation generated by LQG bounce is consistent with the eternal inflation?
