One of the greatest challenges of modern physics is to find a coherent method for describing phenomena, on the cosmic and microscale. For over a hundred years, to describe reality on a cosmic scale we have been using general ...
The mini-halos of dark matter scattered throughout the cosmos could function as highly sensitive probes of primordial magnetic fields. This is what emerges from a theoretical study conducted by SISSA and published in Physical ...

A new Scientific Reports study proposes an extension of the electron Born self-energy (eBse) model, unveiling a mechanism for cosmic inflation driven by a constant potential energy density, thereby challenging the conventional ...
It's a classic tale of apocalyptic fiction. The sun, our precious source of heat and light, collapses into a black hole. Or perhaps a stray black hole comes along and swallows it up. The End is Nigh! If a stellar-mass black ...

By analyzing the early data from the Dark Energy Spectroscopic Instrument (DESI), an international team of astronomers has identified 95 new extremely metal-poor galaxies at a low redshift. The finding is detailed in a paper ...
Shane Palacat-Nelsen's voice drops to a reverent tone as he tells the story of the snow goddess Poliahu who Native Hawaiians believe inhabits the summit of Mauna Kea, the highest point in Hawaii.

Thought to make up 85% of matter in the universe, dark matter is nonluminous and its nature is not well understood. While normal matter absorbs, reflects, and emits light, dark matter cannot be seen directly, making it harder ...
