Unraveling the Universe's Expansion: The Enigma of the Supervoid
Scientists propose that the discrepancy in measurements of the universe's expansion rate, known as the Hubble Tension, could be explained if our galaxy, the Milky Way, is situated in a two-billion-light-year-wide void called the Keenan-Barger-Cowie supervoid. This hypothesis challenges the standard model of cosmology and suggests that a modified theory of gravity, called Modified Newtonian Dynamics (MOND), could replace the need for dark matter. However, this idea is highly debated among astronomers, and alternative methods of measuring the expansion rate also contradict the hypothesis.
