Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What ...

Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...

Dark matter, though invisible, weighs heavily on how we understand the universe. Its gravity sculpts galaxies, holds clusters together, and shapes cosmic evolution—yet we still don’t know what it is.

After decades of hunting, physicists still don’t know what makes up most of the universe’s matter. Now they need to cast a ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

Two fresh ideas are giving scientists new ways to think about how the universe’s hidden mass came to be. Together, they paint a richer picture of dark matter’s origins and how we might still discover ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a grand, cosmological scale, though disproving them can be particularly hard ...

The study of gravitational theories and dark matter dynamics lies at the heart of contemporary cosmology and astrophysics. General relativity provides the prevailing framework for gravity, yet ...
