When this flowchart was written, it was
**known**
that Omega=1, Lambda=0, and H0=50. When I first posted this on the web
(I think in the early '00s), it was
**known**
(with the same high confidence by the same perpetrators)
that Omega=0.27, Lambda=0.73, and
H0=72. That has now (2022) evolved to Omega=0.31, Lambda=0.69, and H0=67 - again,
**known**
with the same high confidence by the usual suspects.
The situation described by the flowchart has changed rather
less in that time.
