WebJun 8, 2024 · In astrophysics, dark matter is a theoretical form of matter that makes up approximately 85% of the matter in the universe. The existence of this invisible force is implied through a variety of observations in the universe, including gravitational effects that cannot be explained by accepted theories of gravity. WebFeb 2, 2024 · We argue that generic features of string compactifications, namely a high supersymmetry breaking scale and late time epochs of modulus domination, might imply superheavy neutralino dark matter with mass around 10 10 –10 11 GeV. Interestingly, this is the right range to explain the recent detection of ultra-high-energy neutrinos by IceCube …
