Scientists suspect that the Earth’s mantle contains a large amount of dark
matter, which is believed to make up 27 percent of the universe.

According to a publication by Live Science, physicist Paul Sutter explains
that European researchers have not yet published their findings on the presence
of radioactivity detected in the upper part of the Earth’s ionosphere, where the
sun ionizes atoms, forming plasma, ultraviolet and x-ray emissions.

According to most scientists, these emissions are the result of interactions
between the particles of dark matter, which make up a small fraction of the
particles in the universe and are difficult to detect.

Instead, the researchers propose looking for other particles, such as weakly
interacting massive particles (WIMPs) or axions, which are subatomic particles
of extremely small mass.

“Thanks to hypothetical particles called axions, these particles of dark
matter can interact with astronomical objects, in particular with massive
celestial bodies, to influence the trajectory of one of the largest cosmic
structures,” explains Sutter.

“Axions have an extremely small reciprocal mass and can interact via weak
electrical interactions, which can be much stronger than the mutual interactions
of WIMPs and axion-like particles characterized by massive gravitational fields
and photon radiation,” write the researchers.

Moreover, the ionosphere is very close to us, which makes it a convenient
place for exploring dark matter.

“The form of this dark matter is of an upper asthmatic order, and it is
located in the same energy range as the radioactivity plotted in the gap of the
respective spectrum,” writes Sutter.

“But if it turns out to be viable, this will be a golden opportunity for us
to study one of the most enigmatic substances of our universe – one of the most
mysterious substances in our cosmic arsenal right in the corridor of our
cosmological journey,” the scientist concludes.
