Ever since astronomer Edwin Hubble in 1929 observed the rate at which the Universe expands, called the Hubble constant H0, astronomers have been arguing about its actual value, as they realised that there was a discrepancy in this number between early universe observations and late universe observations.
Some unknown “ingredient” in cosmic space is forcing the Universe to expand faster than scientists’ models predict, according to the latest measurements with the Hubble Space Telescope.
