Recent studies published in Physical Review D on September 16 and 17 have proposed that microscopic black hole may exist within Solar systemPotentially affecting the paths of planets and satellites. These objects, called primordial black holes, are thought to have formed during the early universe. Estimated to have the mass of an asteroid but dimensions comparable to a hydrogen atom, they are being suggested as possible contributors to the puzzle of dark matter, which constitutes 85 percent of the matter in the universe.
Planetary orbits and primordial black holes
It is theorized that primordial black holes originated from dense regions of the early universe that are collapsing in on themselves gravityAccording to a research, unlike black holes formed from dying stars, these objects are much smaller and faster, with an estimated speed of about 200 kilometers per second. paper,
The gravitational effects of such black holes on the orbits of planets are being studied. It was explained to Science News by Dr. Sarah Geller, a cosmologist at the University of California, Santa Cruz, that fluctuations in a planet’s orbit around the Sun may be caused by the gravitational pull of a primordial black hole. A detailed modeling of the solar system is planned by his team to explore this hypothesis.
Satellite disturbances as a detection method
A different method involving the observation of satellite movements has been proposed by Dr. Bruno Bertrand of the Royal Observatory of Belgium as well as Dr. Sébastien Claesse of the Université Libre de Bruxelles. It was suggested that small black holes could subtly change the satellite’s altitude, making their detection possible. It was stated that existing probes could potentially be used to measure such disturbances. This method was shown to be particularly effective for small black holes.
Limitations and complications
The feasibility of detecting primordial black holes was questioned by Dr. Andreas Burkert of Ludwig-Maximilians-University Munich. It was noted that other factors, such as solar winds or asteroid interactions, could mimic the gravitational effects caused by black holes. It was further commented that although the detection of these objects is considered rare, the possibility cannot be completely ruled out.
The research has offered promising approaches to uncovering these elusive objects, which have the potential to address important questions about the universe, including the nature of dark matter.
