Please do forgive another post today. I suspect I will shortly be almost as absent as Jisbond because I am in a crisis of bill-paying
in ways that are more convoluted than usual...
and I have to go full-on to some of that

Hi Paul, Oh Great One...as you know,
Aurino is right that this topic is extremely
important. It's impressive that Aurino and you're getting to
it.

Aurino could easily be referring to the first few pages of Relativity. He is also saying interesting things. Only a full-on time-earned
understanding of Dick's recent essays here will
give me enough to evaluate him. It's one of the last things I'll try to do in the next week while I'm devoting most of my time to rustling up a few hundred dollars.
Even Paul's light problem and Berkeley will wait a little longer.

Limited time travel certainly is possible if it there is no mandatory universal single time which rules all the universe within "sub-light light distances" of one another.
There are other cases too.
But this first kind of time travel only allows us to travel into the future at different rates compared to one another. Surely it is true
physiologically, psychologically etc., but so far, the rate at which our debts collect interest must be agreed upon by all, time traveling or not.

You guys and gals are fantastic.
Mike
