Eight planets, hundreds of satellites, thousands of asteroids and billions of comets revolve around the Sun. There is no danger of black holes entering a quiescent solar system. But if it could enter, what would happen? What would a black hole absorb the solar system?

Astronaut Black Hole

A black hole is not a hole itself. When a lot of mass accumulates in a very small area, it bends the sheet of spacetime like a hole. We call it a black hole. Due to their high density, their gravitational force is very high. So much so that once a certain area is crossed, nothing can override this attraction. Merges with the black hole.

There is no shortage of black holes in the universe. Just as supermassive black holes sit at the center of galaxies, stellar black holes or stellar black holes are constantly formed from stellar debris. Not all black holes stay in one place. May change location to collect fuel. Let's say, such a black hole entered the solar system. In that case, how would the events?

Whether the existence of the entire solar system would be threatened by a black hole depends on how big the black hole is and how close it is to the solar system. At the center of our galaxy is a supermassive black hole. The name is Sagittarius A*. The black hole is about 4 million times heavier than the Sun.

In front of such a heavy and large black hole, the probability of survival in the solar system is almost zero. Not only that, but due to its size, the black hole would cause problems for us even if it is several light years away. A large number of planets, moons, stars and meteors surround the nomadic black hole. On the way to come, these would accompany the black hole. All of this would be hot as it spins to fuel the black hole.

A few light-years away, these hot cosmic objects started raining in the solar system. Perhaps the impact of a dead planet would have made the world green by then. That is, even if the supermassive black hole is far away, there is a risk of destruction of the entire solar system including the Earth.

Now if the black hole is small, meaning the black hole is formed after the death of the star, then what would happen? They can be up to twenty times heavier than the sun. If such a black hole touched the edge of the solar system, a kind of gravitational collapse would occur in the Oort Cloud.

Oort cloud refers to the habitat of asteroids, meteors, comets located at the boundary of the solar system. Due to the strong gravity of the black hole, these objects would have moved towards the interior of the solar system. Terrible meteor showers began on the planets.

But the event is just the beginning. If the black hole were to pass directly through the solar system, the planets would be knocked out of orbit. turned into fuel. At the distance of Pluto from the Earth, the black hole would have a direct gravitational effect on the Earth. Earth was slowly drifting away from the habitable zone of the solar system towards a black hole. Whether people can adapt quickly to this change is a question.

Of course, there was not much time in that situation. As the black hole approaches, the Earth's crust begins to crack. Earthquakes and eruptions began violently. Along with that, there were natural disasters like storms and floods. The entire surface was covered in molten magma. In such an environment, the structure of the planet would have changed. The Earth would have ended by slowly turning into hot plasma at the event horizon around the black hole. But none of you and I would have lived to see this. Long before that, life would have disappeared from the earth.

But with a bit of luck, the Earth would have been ejected from the solar system during unstable gravity. Earth would become a cold lifeless wandering planet. If only Earth, many planetary satellites including Earth would have survived due to stellar mass black holes. They can be scattered in space without falling directly into the black hole to survive. But the probability of any of that actually happening is close to zero.
