In the results of a study published in the journal Physical Review D, the possibility of using Ganymede to search for آثار (traces/effects) of dark matter appeared. The study explained that the collision of small clumps of dark matter with the moon’s surface may have left clear “scars,” which could be a target for future NASA space missions.
The research stated:
“In theory, dark matter clumps within certain mass ranges can collide with planets and celestial bodies and generate surface structures that remain for long periods of time spanning many geological eras. Calculations show that Ganymede, Jupiter’s largest moon, represents an ideal tool for searching for آثار (traces/effects) of such collisions, due to the extreme age of this moon’s surface.”
Researcher William DeRocco from the University of Maryland in the United States reached this conclusion as part of a project aimed at finding natural alternatives to the artificial detectors used to detect dark matter, which have not yet recorded any conclusive evidence of its existence, partly due to our limited knowledge of the properties of its particles and its irregular distribution in space.
DeRocco explained that large clumps of dark matter must periodically approach or pass through planets and other small celestial bodies, which is very rare from a human perspective. However, these collisions occur frequently according to geological and astronomical standards, at a rate of once every 10,000 to 100,000 years, allowing their آثار (traces/effects) to be traced on the surface of Ganymede and other celestial bodies that have maintained their shape for several billion years.
