A new theoretical research has made a stunning revelation that the Earth is currently crossing an ocean of dark matter and this invisible ocean's waves have been slamming against the upper atmosphere of our planet and generating detectable radio waves.
As per the research, these detectable radio waves have been helping in finally finding this universe's elusive component.
A lot of astrophysical and cosmological evidence, like certain galaxies' inexplicable rotation curves and the largest structures' growth in the cosmic space, has pointed towards the dark matter's existence.
The attempts made to explain these observations with alternative formulations of gravity have not succeeded. Astronomers currently believe that dark matter is some kind of matter which only rarely interacts with normal matter or light.

According to scientists, dark matter is made of massive particles, however, the search for such kinds of particles has not yielded any results.
An alternative, as per the scientists, is that dark matter is exceptionally light and exists as either a form of theoretical particles called "axions" or like an exotic form of photon which carries a bit of mass.
Dark matter, with its incredible lightness, is millions of times lighter in comparison to the lightest known particles and can act in strange ways.
The dark matter, instead of looking like individual point-like bullets, will behave more like large waves which are sloshing around the cosmos.
Scientists say dark matter's interaction point is ionosphere
In a recent study, which was published to the preprint server arXiv, the models of ultralight dark matter, which were not entirely dark, were explored by physicists and they allowed it to interact extremely rarely with normal matter.
In the universe, the plasma is being spewed by all stars in the form of stellar wind.
The production of radio waves has been explored because of the dark matter interacting with environments like the interstellar medium or the solar corona.

In the new research, an interaction point - which is very close to Earth - has been discovered by scientists which is our planet's ionosphere.
The ionosphere of the Earth is the thin and hot layer of the upper atmosphere and it is filled with a loose collection of ionised (charged) particles — which is a plasma.
In this, the waves are sloshing through it and the researchers have found that those waves can interact with hypothetical dark matter waves, which are said to be washing over Earth.
