The statement that all matter is a wavelength might be an oversimplification or misunderstanding of certain concepts in physics. Matter can exhibit wave-like properties under certain conditions, but it is more accurate to say that matter is composed of particles such as atoms and subatomic particles.
In quantum mechanics, particles such as electrons can exhibit wave-particle duality, meaning they can behave as both particles and waves. This duality is described by wavefunctions, which are mathematical functions that represent the probability distribution of finding a particle in a particular state.
However, it is important to note that the wavelength associated with a particle is related to its momentum, and different particles can have different wavelengths depending on their energy and momentum. So, it would not be accurate to say that all matter in the universe is one big wavelength.
Furthermore, the universe is composed of a vast number of particles, ranging from individual atoms to massive galaxies, and their behaviors are governed by a variety of physical phenomena. It is a complex and diverse system, and it cannot be accurately described as a single wavelength.
In summary, while matter can exhibit wave-like properties under certain conditions, it is not accurate to say that all matter in the universe is one big wavelength. The behavior of matter is more accurately described using the principles of quantum mechanics and the laws of physics that govern the interactions of particles.
