How do black hole jets influence cosmic evolution?

Black hole jets are like supercharged fire hoses in space that can shape and change galaxies over time.

Imagine a black hole is like a giant vacuum cleaner at the center of a galaxy. But when it eats too much, it gets angry and shoots out powerful jets, like water shooting from a fire hose. These jets are made of superheated particles traveling at nearly the speed of light!

These jets can go all over the galaxy, heating up gas and dust that would otherwise form new stars. It’s like if you had a big box of Legos ready to build something cool, but someone came in and blew hot air everywhere, making it too warm for the Legos to stick together. That’s what black hole jets do to star formation.

Sometimes, these jets even shoot out into space, helping to create new stars in other places. It's like throwing seeds from a plane, some land near home, others go far and start growing in new soil!

So, over time, black hole jets can either stop or help galaxies grow, they're like the cosmic gardeners of the universe!
