Question

Did you know? Edwin Hubble formulated Hubble's law in 1929: the farther a galaxy is, the faster it moves away from us. The proportionality factor — the Hubble constant — tells us how old the universe is (~13.8 billion years). But measurements by different methods have given conflicting numbers for years — the "Hubble tension".
