What is Eris?

Eris is like a playful friend who loves to cause little surprises and make things more interesting.

Imagine you're playing with your favorite building blocks. You stack them up neatly, ready for a tower. But then, whoosh!, Eris comes in and knocks the whole thing over just for fun. That’s what Eris does: she causes small changes or disturbances that can lead to bigger events.

How Eris Works

Think of Eris like a tiny but clever person who likes to push things just enough to make them move. In real life, scientists sometimes use the name Eris to describe something similar, a little change that makes things act differently. Like when you add one more block on top of your tower and it finally tips over.

Eris doesn’t try to be big or loud; she’s quiet and sneaky. But her small actions can have big results, just like how a tiny push can make a whole tower fall!
