Estimation of the Age of the Universe Based on the Light Universe Theory: A Reverse Calculation from CMB Wavelengths

This study proposes a novel approach to estimate the age of the universe based on the Light Universe Theory, which interprets redshift as the energy loss of photons rather than a consequence of cosmic expansion. Using observed wavelengths of the cosmic microwave background (CMB) and assumed initial photon energies, the elapsed time from photon emission to observation is reverse-calculated, resulting in an estimated universe age of approximately 11 billion years. The approach explains the extremely long wavelength of the CMB as a natural consequence of rapid energy loss associated with the early universe’s local energy density diffusion. This method provides an alternative perspective to conventional cosmological models and demonstrates a new way to connect observational data with universe age estimation.
