How Supermassive Black Holeslife saver For Galaxies
Supermassive black holes, found at the centers of large galaxies, act like hearts, providing the energy needed to support the galaxy.
These black holes emit jets of gas and radiation from their poles, which function like lungs, maintaining the balance of the galaxy's growth.
The jets slow down star formation by preventing interstellar gas clouds from cooling and condensing, thus curtailing the growth of galaxies.
The jets' action is likened to breathing, where pulses from the black hole create shock fronts, similar to how the thoracic diaphragm moves in our chest.
Observations, such as those in the Perseus galaxy cluster, support this phenomenon, showing large gas bubbles caused by soundwaves in the galactic medium.
The black hole needs a steady gas supply to create jets, much like maintaining a proper breathing rate.

Factors like the type of pulsation, size of the black hole, and quality of the jets must be just right to support the galaxy's ambient gas and fuel the black hole.
This mechanism helps extend the lifespan of galaxies by limiting the amount of gas collapsing into stars, preventing them from exhausting their fuel supplies too quickly
Without this process, many galaxies would have exhausted their star-forming fuel by now, resulting in "zombie" galaxies filled with dead or dying stars.
