The current dominant interpretation in theoretical physics is far closer to Heraclitus’ flux, which imagines a universe in constant transformation, where particles are not solid entities but fleeting excitations in dynamic fields. In this view, reality is a process (only occasionally a substance) shaped by tension, motion, and continual becoming -- this idea is not new, but a form of magical thinking that Epicurus considered and rightly rejected.
"The Stoics together with Heraclitus say that matter is wholly and completely changeable and alterable and mutable and fluid." Aetius 1.9.2
