Ton 618 is an extremely massive and supermassive black hole located in the direction of the constellation Canes Venatici, while Sagittarius A* (Sgr A*) is the supermassive black hole at the center of our Milky Way galaxy. Comparing the two, Ton 618 is significantly more massive than Sgr A*, with an estimated mass of tens of billions of times that of our Sun, while Sgr A* has a mass of about 4 million times that of the Sun.
If we were to hypothetically replace Sgr A* with Ton 618 at the center of our galaxy, several significant changes would occur:
Increased gravitational influence: Ton 618's higher mass would result in a much stronger gravitational pull compared to Sgr A*. The orbits of stars, planets, and other celestial bodies in the galaxy would be significantly affected. Stellar orbits closer to the black hole would become more unstable, potentially leading to disruptions and collisions.
Altered accretion disk: The accretion disk—the disk of gas and dust spiraling into the black hole—would be significantly different. Ton 618's stronger gravity would result in a larger and more energetic accretion disk compared to Sgr A*. This could lead to increased activity, such as the release of more energy in the form of radiation and powerful jets.
Effects on galactic structure: The increased mass and gravitational influence of Ton 618 could potentially disrupt the overall structure of the Milky Way. It could influence the distribution of stars, gas, and dust, leading to changes in the shape and dynamics of the galaxy over long timescales.
It's important to note that the precise consequences of such a scenario would depend on many factors, including the interaction between the black hole and the surrounding environment, the characteristics of the accretion disk, and the behavior of nearby stars and other objects. Our understanding of black holes and their influence on galactic structures is still evolving, and further research and observations are needed to provide more accurate predictions and insights into such scenarios.
