Galaxies are like those disco parties in the universe, with stars dancing to their own cosmic beats. Sometimes, things get wilder than a dance-off between planets. Imagine a cosmic tsunami, not the kind that gives you a beach day scare, but one that's so powerful it could rip an entire galaxy apart. Supermassive black holes are like the DJs of this galactic party, keeping everything groovy. But sometimes, things get a little out of control. Suddenly, the black hole gets greedy and starts gobbling up more than it can chew – gas, stars, the whole shebang. This creates a massive cosmic burp, sending shockwaves through the galaxy like a galactic sneeze.
