Harvard astrophysicists have figured out how to check whether the “X-Planet” is a tiny black hole: this can be tracked by the small light signals that will form after the black hole absorbs surrounding objects. A detailed article on this was published by the Astrophysical Journal Letters.
Five years ago, two American planetologists said they found the first traces of the mysterious “X-planet” – this is the hypothetical ninth planet of the solar system, which is located at least 100 billion kilometers from the Sun and is similar in size to Neptune or Uranus.
At the moment, the location of the alleged cosmic body has not been established, the researchers only managed to narrow down the area where it might be located, as well as find new hints of its existence.
There are several versions on this score: some astrophysicists admit that the X-Planet is not really a gas giant, not a large Earth-like planet, but a much more unusual object – the so-called primary black hole. This is such a miniature analog of ordinary and supermassive black holes, which in mass are comparable not with stars and galaxies, but with planets. Presumably, such objects appeared even in the first instants of the existence of the Universe due to the fact that matter was unevenly distributed over its space.
It is difficult to detect such an object, however, the most sensitive telescopes on Earth can still notice the primary black hole. One important feature of the primary black hole is that miniature flashes will occur around it, this happens after the attraction of the black hole will tear apart an object with a diameter from a few centimeters to several hundred meters. Only the LSST Observatory, which is located in Chile, can detect such minor signals.
According to the predictions of scientists, it will be possible to find the tracking of the existence of a black hole in the first three years of operation, provided that the object is comparable in mass with Jupiter or much smaller.
