Unraveling the Mystery of the Supervoid: Could it Solve the Hubble Tension?
The Milky Way galaxy is located on the edge of a massive void called the Local Void, which is part of an even larger underdensity known as the Local Hole or Keenan-Barger-Cowie (KBC) supervoid. This supervoid challenges the standard model of cosmology, which assumes an even distribution of matter throughout the Universe. However, a new study suggests that the Local Hole could help explain the Hubble Tension, which is the discrepancy in measurements of the rate at which the Universe is expanding. By considering the effects of the Local Hole, researchers propose using the Modified Newtonian Dynamics (MOND) theory to better understand gravity and resolve the inconsistencies in our current understanding of the Universe.
