Black holes are like mothers-in-law, some might say: you have to avoid them at all cost and stay as far from them as you can, or else they may destroy you forever. Although nobody knows for sure what falling into a black hole may lead to, it’s obvious that such a gravitational pull which attracts even light can torn anything to pieces before they hit any bottom. And I hate to disappoint you, but the scenario from Interstellar with Cooper being helped by a black hole to travel back in time is just science fiction.
But what would happen if a black hole exists in our own backyard? This is the outstanding idea that a team of physicists is proposing in a forthcoming paper posted on the preprint server arXiv.
The black hole may actually be “Planet Nine”
Distant objects of our Solar System have some very peculiar orbits; therefore, scientists found an explanation: the hypothetical existence of a 9th planet beyond Neptune. And as you might have already known, Pluto is only a dwarf planet, not a proper planet in order to qualify as the 9th planet of the Solar System.
“Planet Nine” cannot be seen with a telescope because if it exists, it’s too far away to be possible the reception of enough light from the Sun on its surface. Therefore, some physicists say that the planet may actually be a small black hole.
Could such a black hole be a threat to Earth?
As we all know, black holes are extremely dangerous. But if you don’t get close enough to one, it will mind its business. If there is a black hole beyond Neptune as physicists are supposing, it’s impossible to do us any harm since it lies between 45 billion and 150 billion kilometers from the Sun. That’s a maximum of 1000 times our planet’s distance from our star, which even at astronomical scale means pretty much.
Astronomers will soon try to prove if “Planet Nine” is actually a black hole, by using Earth-orbiting Fermi Gamma-ray Space Telescope to try to detect releases of gamma rays dwelling in the Solar System.
