This question does not relate to philosophical romanticism applied to science that had some currency in the 1800s. Roughly it seems that scientific romanticism differed from enlightenment by inserting humanity into nature and seeking union via human consciousness and problem solving.
The romantic aspect of physics I allude to shares some features of the medieval tale relating to chivalry, such as Don Quixote and qualities of adventure into unknown parts remote from settled life, such as the adventures of Richard Burton, who translated the Arabian Nights.
The mystery is: how has nature contrived these things we observe?
The remoteness is that the answers may require extrapolation in size, microscopic or cosmological, or in length of time, short or long, or in eons past or yet to arrive, remote from human experience, or principles that defy and challenge human perception, such as universal gravitation, or the nature of time, curvature of space, or quantum particles.
The adventure involves all the steps to solve the problem.
It seems to me that theoretical physics is a romantic quest. If the physicist arrives at a partial or provisional understanding of some mystery, then that is a great romance.
