If
there are waves and fields, if there is the electromagnetic spectrum, as
Einstein reminded colleagues there is, and nuclear forces and gravity, then
waves and fields, the spectrum, nuclear forces and gravity are real.
That produces a problem, and a problem produces knowledge of the problem that leads to many theories and speculations.
It also leads to work on the problem.
We may get closer to an understanding, even an explanation, one day. That idea is real too - part of the problem.
Meanwhile, some will go on tackling the problem and others will go on theorising and speculating about it. Both and both together.
You've got to accept and allow for the fact there's the problem and there's us, intertwined, indissoluble.
