Hypothesis on the nature and origin of cold dark matter

TL;DR

This paper hypothesizes that cold dark matter originated from ultra-light fermionic particles, likely neutrinos, which evolved into cosmic-scale quantum fields, and suggests a shared origin with supermassive black holes, providing testable mass predictions.

Contribution

It introduces a novel hypothesis linking dark matter to ultra-light fermionic particles and their quantum evolution, including entanglement and a common origin with black holes.

Findings

Predicts a minimum mass for supermassive black holes consistent with observations

Proposes dark matter evolved from neutrino-like particles after the Big Bang

Highlights the role of quantum interference and entanglement in dark matter formation

Abstract

One of the greatest mysteries in astrophysics and cosmology is the nature and the origin of cold dark matter, which represents more than 84% of the mass in the universe. Dark matter reacts on and produces gravitational forces and governs the dynamics of stars around galactic centres, however, does not absorb or emit any kind of electromagnetic radiation. So far, any relation to known types of matter has not been conclusive, and proposed new particles have not been found. Here, I propose and discuss how dark matter evolved from ultra-light fermionic particles that decoupled from the rest of the universe shortly after the Big Bang. My description explicitly considers their interference, and reveals the emergence of entanglement between two such particles, as well as their transformation to massive dark-matter quantum fields of cosmic sizes. Furthermore, I argue that dark matter and supermassive black holes have the same origin and evolved simultaneously. If the particles' decoupling time was about half a second after the Big Bang, my hypothesis predicts a minimum mass for supermassive black holes that fits well to the smallest known such object of 50,000 solar masses. It seems very much likely that the ultra-light fermionic particle was the neutrino.
