So if you haven't watched the film, basically there's this one character who suffers from a (fictional) condition referred to as “molecular disequilibrium.” As described by the character, it's a condition where “Every cell in my body is torn apart and stitched back together, over and over every day.” With said condition, the character can phase through solid objects and living beings at will. Basically she can quantum shift through space.
From what I understand, she had become intangible from a childhood accident but able to solidify her body if she stayed focus. Another character was trying find a way to cure her condition, developing some kind of quantum chamber to allow her to briefly stabilize and ease her pain.
This “molecular disequilibrium” is a concept that I'm interested in, especially because I wanted to apply similar condition where the cells are torn apart and stitched back together to a whole fictional race I'm currently writing. So I'm curious how plausible it is scientifically.
