That being said, there are theoretical frameworks, such as quantum field theory, that describe particles and their interactions in terms of waves or fields. In these frameworks, particles can be viewed as excitations or disturbances in the underlying quantum fields. However, the concept of mass in these theories is more complex and involves interactions with the Higgs field, which gives particles their mass.
It's worth mentioning that there are ongoing efforts to unify quantum mechanics, which describes particles in terms of waves, with general relativity, which describes gravity as the curvature of spacetime. Some physicists are exploring approaches like string theory or loop quantum gravity that attempt to reconcile these two fundamental theories. These approaches often involve waves in higher-dimensional spaces, but they don't necessarily propose that all mass is purely composed of waves.
As scientific understanding continues to advance, it's possible that new theories or perspectives may emerge that could provide further insights into the nature of mass. It's always fascinating to follow the progress of scientific research as it uncovers new possibilities and challenges existing paradigms.
