Wow, how can it suck in one star every day? Think of the distances to the nearest star to us. That is just staggering beyond belief.
“If the Milky Way’s black hole wanted to grow that fat, it would have to swallow two thirds of all the stars in our Galaxy.”
Not a fully formed star every day, but the equivalent mass, about 4 million trillion trillion pounds of gas, dust, asteroids, comets, planets and, yes, a star or two now and then. Get that thing some Tums!
