Some scientists believe that a huge planet that has never been seen by astronomers could be lurking, nearly invisibly, at the dark edges of our solar system. The planet was earlier thought to be Planet Nine or Planet X, however, as per the latest paper by scientists, the gravitational pull behind these planets could be emanating from a "primordial black hole" that has been theorized to form during the big bang, reports Business Insider.
On March 2, 2019 The Galaxy reported that astronomers from the University of California concluded that there are probably tens of millions of enigmatic, dark objects, stellar-remnant black holes lurking in the Milky Way.
Researchers began believing there was something huge on the edge of our galactic neighbourhood, as it could explain why the solar system is slightly off balance.
However, in ours, the planets are at an angle of six degrees off its axis.
Is Planet Nine really an old black hole? The unusual object, they mentioned, might have a mass some 10 instances that of Earth and take as much as 20,000 Earth years to finish one orbit of the Solar because it sits between 45 billion and 150 billion kilometers from our star.
The two scientists reached this hypothesis in a novel way, by observing that two different phenomena could be related: first, the observation of peculiar orbits of trans-Neptunian objects (meaning bodies orbiting our sun beyond Neptune), which might be explained by the presence of a distant planet with 5 to 15 times Earth's mass; and second, the number of "microlensing events", meaning telescope images that had been distorted by gravitational lensing of the kind caused by black holes or other massive, compact objects. "Capture of a free-floating planet is a leading explanation for the origin of Planet Nine, and we show that the probability of capturing a PBH instead is comparable", the astronomers wrote in the paper. Those anomalies would come and go as Planet Nine moves in front of a distant star and continues in its orbit. All of these are theorized to have formed several hundred thousand years after the Big Bang; this is because black holes are now known to develop in the aftermath of supernova explosions and stars take at least that long to form and die. In 2016, computer and mathematical modeling has allowed us to compile a model in which it became clear that the mass of the object (be it a planet, a black hole or anything else) is about 10 times greater than the mass of the Earth. "We advocate that relatively than simply searching for it in seen gentle, perhaps search for it in gamma rays".
