What is at the center of our galaxy? What is at the center of our universe? Black holes? If given enough time would black holes eventually consume everything? (More planets dying creating more black holes ontop of black holes getting bigger as they consume). What happens when there is no more matter left for a black hole to consume? What happens when a black hole consumes a black hole? I feel like black holes play a bigger role in the nature of the universe then we currently understand.

Black holes don't just eat everything in the universe lol.... Once there is nothing within its reach it doesn't have anything to pull in and their reach actually isn't as insane as people think they are If the sun was to magically become a black hole right now, our solar system would remain in orbit around it because its mass is still that of the sun, just more dense.... so if you got close enough, inside mercury's orbit, it would eat the shit out of you lol So then you can assume the galaxy is in orbit around one that's not eating much mass compared to its own mass. So its not devouring the galaxy, its just holding it here
interesting thing to think of... Black holes exist outside normal time and space...once formed all we see and can witness of it having existed is the event horizon and the void at its center (may or may not be a spinning black hole, and this has an effect on how we can observe it)...but we see this in OUR time...not the black holes. Some say the black hole may just pass into another dimension, breaking through to another area in space/time and expel matter/energy (white holes), and no longer exist in our universe/dimension, but we don't notice as those things would occur in its own space/time envelope, not ours... ya..it gets really funky...
On that note, by my calculations the radius of the event horizon of a black hole the mass of the sun will be 2,953m (approx), or less than the distance I run every night. https://www.wolframalpha.com/input/?i=%282%286.67384x10^-11%29%281.988435x10^30%29%29%2F299792458^2 Schwarzchild radius formula, determines the event horizon radius of anything with mass: r=2Gm / c^2 2x Gravitational constant x mass of object in question divide that by the speed of light in a vacuum squared (299,792,458m/s) Also, black holes are hypothesized to decay, but as far as I know it hasn't ever been confirmed and it's on such an incredibly long timescale that it won't matter. All celestial objects being eaten by black holes on the order of trillions of years is one hypothesized end to the universe. One misconception is that they magically eat everything around them, that's not true. Like SIRSOG said in the post I quoted, if the sun were to become a black hole spontaneously, nothing would change about planetary orbit. It'd just get really cold. Black holes are also messy eaters. They rip and destroy more than they eat. Then the remnants of whatever they came into contact with forms an accretion disc and they slowly consume everything within X distance.
