A 'cosmic car radio' could help scientists tune in to dark matter within the next 15 years.

A groundbreaking study published today in Nature reveals a new approach that could finally uncover the elusive nature of dark matter within the next 15 years. Researchers from King's College London, Harvard University, UC Berkeley, and other leading institutions have collaborated on designing a "cosmic radio" detector that aims to be the most sensitive dark matter detector ever created.

The innovative device seeks to detect axions, hypothetical particles thought to make up a large fraction of dark matter. Unlike traditional detection methods, this "cosmic radio" concept would listen for ultra-faint radio signals generated when axions interact with magnetic fields. According to the study, the system could scan a broad range of axion masses, enhancing the likelihood of capturing definitive evidence of dark matter.

Dark matter, which is believed to account for roughly 27% of the universe’s mass-energy, remains one of the biggest mysteries in modern physics. Existing experiments, such as LUX-ZEPLIN and XENONnT, have so far failed to conclusively identify dark matter particles, driving scientists to pursue new ideas.

The proposed "cosmic radio" system will require ultra-sensitive antennas, cryogenic cooling technologies, and sophisticated noise reduction techniques to differentiate potential dark matter signals from cosmic background noise. The research team plans to build prototypes within the next few years, with full-scale deployment envisioned within a decade.

If successful, this detector could revolutionize our understanding of the universe, potentially answering questions about galaxy formation, cosmic evolution, and the fundamental building blocks of reality. Scientists are hopeful that by tuning into the faint whispers of the cosmos, humanity might finally unlock one of the most profound secrets of existence.
