I just bought the book this week. Very interesting so far.
I’ll try to find and post a video some astronomers made recently which shows how large the universe really is-that is the KNOWN universe they have found so far. My brain hurt just trying to conceptulize(sic) the huge numbers they were talking about.
From what I've read so for, I think the only thing I could understand in that book is maybe the cover and the dedication page.......
