Okay kiddo, there's something called "virgocentric flow" and it has to do with how galaxies move in space. Imagine you're playing a game of tag with your friends on a playground. When you run from one end of the playground to the other, you move in a straight line, right?
Well, when galaxies move in space, they don't always move in straight lines. They can be influenced by something called gravity, which pulls them towards other objects. One big object in space is the Virgo Cluster, which is a group of galaxies that are all hanging out together.
Because the Virgo Cluster is so big, it can pull on other galaxies and change how they move. This is called "virgocentric flow" because it's like everything in space is working towards the Virgo Cluster as a center point. Sort of like how all you and your friends might gather around one spot on the playground because that's where the coolest game is happening!
So, scientists have studied how galaxies are moving in space and have noticed that many of them seem to be moving in a way that is influenced by the Virgo Cluster. It's like the Virgo Cluster is the big kid on the playground and everyone else is following along!
