Two recent studies by Professor Stefano Profumo of the University of California, Santa Cruz (UCSC), have proposed innovative theories that seek to answer one of the most fundamental questions in modern physics: what is the nature of dark matter? Despite science confirming its existence, accounting for nearly 80% of all matter in the universe, its origin and properties remain a mystery.
The research suggests that dark matter may have formed under extreme conditions in the early universe without requiring detectable interactions with ordinary matter. The most recent study proposes that dark matter arose in a hidden sector, governed by its own particles and forces but subject to physical laws similar to those of the known universe. This idea is based on quantum chromodynamics (QCD), which explains how quarks bind together to form protons and neutrons via the strong nuclear force.
The theory also explores the possibility of ultradense primordial black holes forming under extreme conditions in the early universe, which could explain the distribution of dark matter in the cosmos. These objects would be invisible to particle detectors due to their gravitational interactions alone.
A second study published earlier proposes that dark matter was generated during a period of accelerated expansion in the universe shortly after cosmic inflation. This mechanism is based on quantum field theory in curved space-time and does not require assumptions about dark matter interactions, only stability and gravitational production.
Both theories are highly speculative but offer self-contained frameworks that maintain links with known physics, avoiding baseless speculation. They aim to provide alternative paths for solving one of the biggest mysteries in modern physics, a challenge where traditional experiments have yet to yield conclusive results.
