The recent publication by Durham University and the University of Illinois in Chicago suggests that what was previously considered an invisible planet on the edge of the solar system is actually an ancient black hole. The scientists claim that the new conclusion explains the phenomena better than anything else that has been previously proposed.
The researchers expressed concern about the results, as the outer regions of the solar system have "strange" gravitational orbital anomalies.  Concerns were raised when Poland's OGLE (Optical Gravitational Lens Experiment) recorded a series of gravitational anomalies.
The oddities of gravitational attraction prompted the University's researchers to suggest the presence of a primordial black hole (PBH) instead of what scientists earlier called "Planet 9".
They believe that the black hole is ancient and originated in the first second after the Big Bang and was somehow captured by our solar system.
Scientists believe a black hole might linger on the edge of the solar system
The proposed black hole is in our solar system.
The authors regard this idea as likely as a planet 9.
The possible existence of a black hole at the edge of the solar system raises the question of whether the Earth and the surrounding planets will one day be involved.
Fears were heightened as scientists explained that the black hole hypothesis, if true and in the same area as the proposed planet 9, is about 56 billion miles from Earth.
This is less than a single light year – 6 trillion miles – astronomically extremely close.

Professor Scholtz quickly downplayed all fears and explained: "For normal black holes you need at least one solar mass, because it is made up of a star.  "These original black holes can be much lighter, such as a mass of earth or even lighter."
This means that the proposed black hole would be tiny and probably not big enough to be worried.
The scientists have also stated the probability of the presence of the Earth. A black hole or a planet are very similar.

Black holes are one of the most enigmatic by-products of the universe
James Unwin, who Univ The University of Illinois said, "A solution with an ordinary planet and a solution with an exotic compact object such as an original black hole are very similar."
Professor Unwin and senior Durham University researcher, Jakub Scholtz, said Both phenomena can be explained simultaneously by a new population of astrophysikali bodies with a mass several times that of the earth.
They went so far as to assume that the presence of a black hole would be easier to understand because a planet 9 would require a redefinition. Think of planet formation as it would be a free-floating member of a solar system. Interestingly, the proposed PBH may ultimately be more observable than Planet 9 has proven to be indirect.

Professor Scholtz and Unwin say that confirming a PBH by detecting gamma ray signals from its dark matter microhalo could be achieved by people who are not directly observing it can, believe that the deadly interactions between dark matter and normal Matter on the edge of the PBH gamma would produce "annihilation signals" that could supply devices such as the Fermi Space Telescope or the Chandra X-ray Observatory.
The microhalo in question could reach hundreds of thousands of mules from the center of the black hole.
Professor Unwin said, "We actually expect [annihilation signals] to occur at a very considerable speed.
" Things can only be luminous sources in the sky.
The paper published by Professor Scholtz and Unwin is still under review and has not yet been published in its final form. Look for certain methods and considerations that have led to the conclusion.
Scientists say the black hole is astronomically close to Earth
It's also a new idea – the first of its kind whose anomalous orbit is largely due to a rogue planet. Many have called Planet 9.
The two scientists told UIC Today that they knew it at first sight how outlandish their suggestion might be, but quickly justified their conclusion.
Professor Unwin said, "We are without say that it can not be a planet, let's say it does not have to be a planet.
"The important point is that this adds to the experimental search required to find this object that we believe to be in the outer solar system. "
