OK.

OK, why not taking that difference into account. I think it is a
crucial point.

I am not sure I understand.

I could agree, but U cannot *know* e is U. Need some bet or act of
faith.
In general if U describes the observer, he is a "big" number in need of
an explanation. I mean, the existence of "big stable U" is what we try
to explain.

I really don't understand.
