There are Two Black Holes at the Center of our Galaxy!
The formation of our Galaxy suggests that there is a friend on the supermassive black hole. In fact, there are a pair of supermassive black holes. And it's common that pairs of supermassive black holes should exist in the universe.
The supermassive black hole in our Galaxy, called Sgr A*, has a mass of about four Million times that of our Sun.
Almost every galaxy, including our Galaxy Milky Way, has a supermassive black hole at its center, So what is Supermassive black hole. A black hole that is more than a million times the mass of our son is considered supermassive.
Study Suggest that there is a second supermassive black hole with a mass of 100,000 times the mass of the Sun. Supermassive black holes have gotten a lot of attention lately. Because of the recent image of a giant black hole that is in the center of the Galaxy M87.

So what is Black Hole?
Well, a black hole is placed in space where gravity is so much strong that nothing can escape from this force even light can't escape. The scientist is studying Sgr A* from the past 20 years. Around Sgr A* there is a dense cluster of stars by measurements of this dense cluster Scientists have to confirm the existence of a Supermassive black hole, and they can measure its mass. Based on the study, there might be a second black hole nearby Sgr A* it is at least 100,000 times the mass of our Sun. |

If there are two massive black holes in the center of our galaxy orbiting each other, they will emit gravitational waves. The LIGO-Virgo observatories have been detecting gravitational wave radiation from merging stellar-mass black holes and neutron stars.
But we can't detect a gravitational wave from Black holes pair because of the frequencies too low for the LIGO-Virgo to detect. But a space-based detector as LISA maybe able to detect these ways, and we can confirm if there are a pair of black holes or the massive black hole at the center or our Galaxy is alone.
