Galaxy

Real World Example

Imagine you have a messy room where all your possessions—clothes, books, and gadgets—are scattered everywhere, but somehow they all seem to stay in place despite the chaos. This is similar to how a galaxy operates, which is a massive system where countless stars, gases, and dust are held together amidst the vastness of space. Just like gravity acts like an invisible organizing force keeping a galaxy's elements from drifting apart, the walls and structure of your room keep your scattered belongings from spilling out and getting lost.
