The true essence here is that science has two realms: a golden and a silver one, Gary. I think that Tim is trying to show this (but approaching as if Science is a one-thing while that is never the case of course).
An example of silver science is archaeology. It is based on finds, and the finds cannot be repeated. As such, the gold standard of repeatable results is not available. Asking, for instance, for falsification is then not available. One cannot undermine a proposal how artifacts fit together by requesting falsification.
Same for the materialization process. It cannot be repeated, so the gold standard is not available.
I can tell you from first-hand experience that scientists are sitting on their high horses demanding falsification when falsification is not available. I am therefore very glad that Tim is pointing out that scientists can overstep themselves.
The first problem occurs right away when stating that science is a single realm. I hope archaeology and the materialization process show that there are two realms with one not containing repeatable results.
My Big Whisper theory has been killed off by many scientists because they want falsification. As such, this is a very sore point for me. Even without receiving a decent opportunity to discuss, the theory is swept off the table. Meanwhile, the Big Bang theory is based on evidence from the material side of the equation, and does not say anything about how the prior state ended.
You will be happy to read that I am using Newton to make my point. With outbound motion visible among all matter in the universe at the collective level, I propose the opposite caused the prior state of the universe to have damaged parts of itself (and that damage then being the same as matter). Newton: What goes in, must come out.

Thank you for an otherwise good response, Gary.
