The concepts you mentioned relate to quantum mechanics, which governs the behavior of particles at the microscopic level. However, these concepts do not directly apply to macroscopic objects, such as everyday objects we encounter in our daily lives.
In quantum mechanics, particles like electrons and photons are described by wave functions, which represent the probability distributions of their properties. The collapse of the wave function refers to a phenomenon where the wave function transitions from a superposition of multiple states to a single definite state, typically as a result of measurement or interaction with the environment.
For macroscopic objects, such as a chair or a baseball, their behavior and properties are well described by classical physics rather than quantum mechanics. The wave-like behavior of particles becomes negligible at larger scales, and macroscopic objects do not exhibit the same kind of superposition or wave function collapse observed at the quantum level. Consequently, statements (1) and (2) are not applicable to macroscopic objects.
While it is true that all matter, including macroscopic objects, has a wave-particle duality, where particles can exhibit wave-like behavior under certain conditions, the wave-like behavior is typically not observable at macroscopic scales. Thus, it is not accurate to say that macroscopic objects are still waves, even if we cannot detect it.
