There is no way a black hole would eat an entire galaxy. The gravitational reach of supermassive black holes contained in the middle of galaxies is large, but not nearly large enough for eating the whole galaxy.There is no way a black hole would eat an entire galaxy.

Can a galaxy survive a black hole?
Now, researchers have found a galaxy that is surviving the black hole's ravenous forces by continuing to birth new stars – about 100 Sun-sized stars a year.
What would happen if the black hole at the center of the Milky Way exploded?
The black hole would have to take in over 300 million solar masses of gas to create an explosion greater than the one that tore apart the Ophiuchus cluster. And the amount of gas it displaced would equal several trillion Suns. Across the Universe, the blast would rip galaxies apart and destroy planets.
Is our universe in a black hole?
The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity.
Is there a active black hole?
Active galactic nuclei Such black holes are not uncommon; in fact, astronomers have come to the conclusion that there should be at least one of them in the centre of all but a few galaxies.
What would happen if the sun exploded?
The Sun will get hotter and brighter, and it will start to expand. During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
What happens if a black hole swallows Earth?
Ripped apart: The Earth would stand no chance if it encountered a rogue black hole; the cosmic black hole's tidal forces would easily rip the planet apart. Lost in space: Matter piles up in a superheated, rapidly spinning disc before plunging through the horizon of a black hole, never to reappear again.
Is there a white hole?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Do wormholes exist?
Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.
