Black holes in our solar system
Under this text is a link to an article that is published in the Business Insider magazine. There is writing about the possibility that we have a black hole in our solar system(1).
There is one very interesting thing Could we have a black hole in our solar system? (2) Could this be possible? When we want to observe black holes, we must realize that we cannot get observations straight from the black hole. We see the disk of material around it, and here I must say, that we see only the radiation, what comes around the black hole. But inside the point, where escaping velocity would across the speed of light we cannot get the observation.
And that means that we see black holes only when something drops inside them. So if the black hole is orbiting the star in the area, where is not material, that thing would cause that the radiation, what comes from the black hole would be very hard to notice. Or in other scenarios, the material that is dropped in the black hole is pure helium or hydrogen, because the black hole would act similar way with planets, and they will sweep other particles from their trajectory.
That means that the light particles, that are dropped in the black hole would not send very strong radiation, which is hard to detect from the Earth, because it is sending in the form of X-ray frequency. That weak radiation would be lost in the background radiation. There have been speculations that near our solar system can be the very small black hole, what size would be about basketball.
But what could form that kind of black hole? The answer would be that the antimatter explosion could form those really small black holes, which can exist about thousands or millions of years. Those periods are extremely short if we are thinking them at the point of view of the ages of stars like the sun. But even if those black holes would vaporize in a short period, that thing will take a very long time, if we compare that thing to the lifetime of a human.
The vaporization time depends on the things, how much material the black hole can pull inside. And the stars would give the energy to those black holes, which means that the existing time of the small black holes is extremely hard to predict. The vaporization means that sometimes the black holes are losing photons, and what smaller the mass of this supermassive particle goes the loss of photons would increase.
And sooner or later the black hole has finished its existence. When a black hole is in the space, the black holes cannot get anything to eat, and that means that they cannot get more energy. But if the black hole is near the star, that will feed it with energy, and that kind of thing can increase the lifetime of the black holes, which is extremely small.
