How Big Should a Black Hole Be?

We can't see these stars orbiting around the very center of the milkyway. But infra red light can pass through a lot of the gas and the dusns. If you use filters on your telescope to only look through the infa red, you can see these stars. And if you gooble, you can watch these cool movies of these stars. The movies take more than a decade to make, because these stars have ike an orbital period of like 16 years.
