"Revolutionizing Our Understanding of the Universe through Extra Dimensions and Quantum Mechanics"

A new study by the Stellar Standard Candles and Distances research group has achieved the most accurate calibration of Cepheid stars for distance measurements to date based on data collected by the European Space Agency's Gaia mission. This new calibration further amplifies the Hubble tension, which refers to the discrepancy of 5.6 km/s/Mpc in the measurement of the cosmic expansion rate based on the echo of the Big Bang (CMB) or direct measurement based on today's stars and galaxies. The study confirms the 73 km/s/Mpc expansion rate and provides the most precise, reliable calibrations of Cepheids as tools to measure distances to date. The discrepancy has implications for the understanding of the basic physical laws that govern the universe, including the exact nature of dark energy, the time-space continuum, and gravity.
