Astrophysicists have been trying to understand the formation of cosmological objects and phenomena in the universe for decades. Past theoretical studies suggest that quantum fluctuations in the early universe, known as primordial ...
Almost 20 years ago, the DAMA/LIBRA experiment at Italy's Gran Sasso National Laboratory—LNGS began publishing data showing that it had detected a signal modulation produced by an interaction with the Milky Way's dark ...

Dark matter halos are theoretical bodies inside which galaxies are suspended; the halo's mass dominates the total mass. These halos cannot be observed directly, but astronomers infer their presence by the phenomenon of gravity ...
About eighty-five percent of the matter in the universe is in the form of dark matter, whose nature remains a mystery. The rest of the matter in the universe is of the kind found in atoms. Astronomers studying the evolution ...
