Neutrons in dark matter have decayed. Event horizon is struck by neutrons giving the event horizon bulk in the form of kinetic energy from the point of maximum energy pressure to the point of lowest energy density, crosses the Einstein–Podolsky–Rosen bridge. In a vast space, neutrons decay. D.E. (aka: dark energy) is an expansion of 10⁴⁵ decay.

Dark matter, an elusive and mysterious entity, constitutes a significant portion of the universe's mass, yet its nature remains shrouded in ambiguity. The cold dark matter model has long held sway, suggesting that dark matter particles move at slow speeds and form vast cosmic structures through gravitational attraction.

UC Santa Cruz's Supercomputer Exploration

Employing cutting-edge computational techniques, UC Santa Cruz researchers undertook an extensive examination of the nature of dark matter. Their supercomputer simulations revealed intriguing results that defy the conventional cold dark matter model. Instead, the evidence points towards warm dark matter, where particles exhibit higher average velocities.

Warm Dark Matter: A Paradigm Shift

Warm dark matter offers a fresh perspective on the behavior of these elusive particles. In contrast to their cold counterparts, warm dark matter particles move at faster speeds, creating subtle but significant differences in the large-scale structures of the universe.

Implications of Warm Dark Matter

The implications of UC Santa Cruz's findings are far-reaching. By challenging the cold dark matter model, the warm dark matter theory opens up new avenues of exploration in the quest to understand the universe's hidden cosmic components.

A Key Puzzle Piece

The study's implications extend to the formation of structures in the universe. Warm dark matter's higher average velocities offer a plausible explanation for observed phenomena like the "missing satellite problem," where some smaller galaxies are conspicuously absent from the cosmic landscape.

Toward a Unified Cosmological Model

As scientists embrace the concept of warm dark matter, the pursuit of a unified cosmological model gains momentum. Integrating warm dark matter's characteristics into our understanding of the cosmos has the potential to elucidate long-standing cosmic mysteries.

Future Directions

UC Santa Cruz's groundbreaking research serves as a catalyst for further exploration into the nature of dark matter. The scientific community is poised to embark on new experiments and observations to validate and refine the warm dark matter theory.

A Paradigm-Shifting Discovery

The UC Santa Cruz researchers' bold foray into the world of dark matter has unveiled a paradigm-shifting discovery. Warm dark matter challenges conventional wisdom, urging scientists to recalibrate their understanding of the universe's hidden fabric. As the scientific community delves deeper into this cosmic enigma, the quest for a comprehensive and unified cosmological model gains new momentum, taking humanity one step closer to unraveling the mysteries that lie within the vast cosmic expanse. Be well.
