The statement that "all matter is a wavelength" is not accurate. Matter is not solely defined as a wavelength. Instead, matter consists of particles such as atoms, molecules, and subatomic particles like electrons and quarks. These particles have mass, occupy space, and interact with each other through fundamental forces.
However, it is true that particles, particularly at the quantum level, can exhibit wave-like behavior. This is described by the wave-particle duality principle in quantum mechanics. According to this principle, particles can exhibit both particle-like and wave-like properties depending on the experimental setup and observations.
The concept of a "big wavelength" encompassing all matter in the universe is not a widely accepted or supported idea in physics. The universe is a vast and complex system containing a wide variety of matter and energy in different forms. While wave-like behavior can be observed at the quantum level, it does not imply that all matter in the universe can be described by a single, unified wavelength.
It's important to note that our understanding of the universe is continually evolving, and new scientific discoveries may challenge or refine existing models and concepts.
