No, you are the one who believes in the supernatural,
not I. I have confronted those supernatural demons
and decided they don't even exist in reality.
But when the line is cut, it is clear that no
energy is moving between the separate sections.
Just as it is clear that before the cut, energy
was moving between the separate sections. It
requires belief in a supernatural to assert that
is not a change.
When the lines are joined, the voltage, current and
power distributions on the line remain the same.
Therefore, no energy is being transferred between
the now joined sections.
QED
Change the QED to BS and you will have it right.
When the lines are joined, there is no longer a
physical impedance discontinuity so reflections
are impossible and energy starts flowing again
in both directions.
Believing that reflections can occur where there
exists no physical impedance discontinuity is a
religion, not a science. At that point, I draw
the line - but you are free to have the religion
of your choice. Just please don't try to force
your religion on this technical newsgroup.
With or without reflections, no energy crosses
the points on the line with zero current.
Make that no *NET* energy and you will be so
technically correct that I will agree with you.
