Galaxies are amazing structures that make up our universe. They are shaped mostly by gravity, creating a complex web in space.
Cosmic Web: Galaxies are part of a huge system called the "cosmic web." This web includes:
Interactions and Mergers: Galaxies don’t just sit in one place. They can bump into each other and combine. For example, our Milky Way galaxy is on a path to collide with the Andromeda Galaxy. This is expected to happen in about 4.5 billion years!
Dark matter is really important when it comes to how galaxies are organized. It gives mass to galaxies, which helps create their gravitational pull. Dark matter forms a halo around galaxies and impacts how they spin and grow.
In short, galaxies arrange themselves into a wonderful structure that is guided by gravity, interactions, and the mysterious dark matter. This beautiful setup shows us how dynamic and interesting our universe is!
