Given that photons and light waves

Given that photons and light waves will also lose some energy, and photons and light waves will cause chaos in the process of traveling; in order to maintain the characteristics of the light source, the photon's traveling kinetic energy is provided by light waves from the beginning, and light waves rely on high energy waves. The loss guarantees normal photon propagation. As light waves continue to consume energy, the light waves gradually reduce the frequency to provide kinetic energy to the photons. While reducing the frequency, the light waves dissipate the photons that are asymmetric and uncoordinated with the light waves. The photons supported by the light waves are lost and dispersed in the universe. After depleting their own kinetic energy, these photons stay in cosmic space and become a kind of matter with zero mass, which exists in the form of dark matter in cosmic space; there are endless dark matter in the universe, and these dark matter are dispersed in the universe. What's left of photons that are still in space.
