Supermassive black hole

Experts recently discussed what would happen to Earth if the supermassive black hole at the center of Milky Way suddenly enters the Solar System. If this happens, the experts noted that the black hole would destroy Earth in different ways.

The grim topic was discussed in a video made by the scientific YouTube channel What If. In the video, the channel discussed how Earth would get destroyed if Milky Way’s Sagittarius A* black hole suddenly moved and appeared within the Solar System.

Due to the immense gravitational pull of a black hole, it would disrupt the orbit of various objects within Earth’s neighborhood. This means that a black hole, even though its light-years away from Earth, could send comets, asteroids and other space rocks hurtling toward the planet.

“If this kind of black hole made it to the outer reaches of the Solar System, it would cause a gravitational mess in the Oort cloud – the area of icy, comet-like objects,” the narrator stated in the video. “A stellar black hole would hurl more comets and asteroids into the inner Solar System, where they could strike the planets. Earth might take some hits, too.”

Similar to its effect on asteroids and comets, the black hole could also disrupt the orbit of other planets. If this happens, Earth could end up on a collision course with a rogue planet.

Aside from these grim scenarios, the video also pointed out that a black hole could change Earth’s distance from the Sun, nudging the planet out of the habitable zone. Once this happens, a series of extreme environmental events will be triggered on Earth.

“It would pull us out of the habitable zone, and we humans might not be ready to adapt to this change,” the narrator stated. “We wouldn’t have much time to complain, since there would be worse things ahead. As the black hole approaches Earth, it would cause the cracking of the planet’s crust. We’d see extreme earthquakes and volcanic eruptions.”

“The ocean tides would be devastating, too,” he continued. “By the time the black hole passed Earth’s orbit, there would be nothing left of our planet but a sterile surface paved with magma.”
