Hi, I am attempting to consider theoretical physics from an artistic point of view, i.e. can processes used in theoretical physics be applicable to art, and if so - how. With the above in mind, I was wondering if someone could help me understand the focus of theoretical physics. As far as I understand it: Theoretical physics applies to general aspects which can be applicable to various instances. Or is it the case that if one can, for example, describe a totally new and independent material/phenomena that it's related laws are applicable only to itself and only in a very particular situation? How limited theoretical physics is to the already known? There are theories about, for example, dark matter/energy which in itself wasn't yet encountered but other observations point at the possibility of its existance. However, if one completely invented a material with no observational evidence for what-so-ever, other than the theoretician's will for that material to be considered via their theory - would that still be theoretical physics, or simply fictional physics..? Many thanks for any reflections on this.
