BTW, for years, I have been a big fan of Schroeder...
FWIW, I'm already considering a slight "tweak" to this "draft" slide...
In trying to understand this concept of time being relative to your position I'm stuck on how Schroeder determined the time and size of the universe at the end of the 1st day. I understand the idea that God pre-existing the begining was outside time all together and thus was outside time at the begining/big bang.
It's the break points for day 1, 2nd day, etc. that I have a hard time understanding. I'm assuming that his thought is that outside the universe in what we measure as 24 hours would be 8 billion years if we were measuring time from the center to the edge of the expansion and then the 2nd day would be half that and each succeeding day half the previous day.
