Copper anneals at dull red heat and melts within the range of cherry red
heat. Presuming that melting the tube is an undesirable result, the right
method is set by physics and is not simply an opinion.

The ?laws? of science, including physics, are *only* an agreement by
scientists in general that this is the best idea of reality we have at the
moment. Popper IIRC believes that all "Scientific laws" will be
overturned or drastically modified within 200 years of formulation.

Which is utterly irrelevant.
Deeper understanding of the physics of copper does not change the
underlying physics of how it behaves when heated.

The mechanics of forming copper have not changed throughout human
history - and what happens when you bend it and heat it is unlikely to
change in the future.

New physical laws have to fit within existing observations, which means
that it's very, very unlikely anyone will work out a different way to
anneal copper using heat.

Many areas of physics have been explored with exquisitely sensitive
instruments, and all the existing laws work down to those scales.

If you have a new theory, it is only useful if it conforms to all
existing experiments - or it's patently false, or if it differs in some
way from existing theory in some way that's testable.
