Scientists have theorized that Earth’s upper atmosphere known as the ionosphere could interact with hypothetical dark matter particles passing through our planet.
Dark matter is an invisible and unknown form of matter that makes up most of the matter in the universe but interacts very rarely with normal matter.
Some theories propose that dark matter could be made up of very light and wave-like particles instead of point-like particles.
According to a new study, waves in this proposed ultralight dark matter could resonate with plasma waves in Earth’s ionosphere.
This resonance could generate detectable radio waves that may allow scientists to study the mysterious dark matter.
Researchers suggest using carefully tuned radio antennas to search for specific frequencies of radio waves over the course of a year.
The ionosphere is a promising location as it reflects many radio signals and is easily accessible for constant monitoring.
Detecting radio waves from dark matter interacting in the ionosphere could provide insights into one of the major unknown components of the universe.
