Experiments reveal the roles of vibrating cosmos and Casimir photons in cosmic microwave background, suggesting new insights into quantum fluctuations.
The cosmic microwave background (CMB) power spectrum is commonly interpreted as the macroscopic imprint of primordial quantum fluctuations amplified during cosmic inflation. However, the physical origin of these fluctuations by which real photons emerge remain conceptually open. We propose two types of photons contributing to CMB power spectrum modeled by tabletop experiments. One is “Vibrating Cosmos Photon” corresponding to coherent vibration of cosmic ball just after cosmic inflation, which is modeled by a tabletop experiment of a vibrating crystalline solid. Another is “Casimir-Photon” generated during Hubble cosmic expansion, which is modeled by the dynamic Casimir Effect experiment. The CMB power spectrum may be sum of those two types. In the last section, a quantized space model of Casimir effect is discussed in detail. This framework invites renewed examination of cosmological data from the perspective of quantized space.
