Okay kiddo, let me explain to you what a pilot-wave is. If you throw a ball in the air, it will always come back down, right? That's because there are some laws that govern how things move in the world, and we call this the laws of physics.
One of the things that scientists study is how tiny particles like electrons move. These particles are so small that we can't really see them, but we know they exist because they play a big role in how everything around us works.
Now, according to one theory called the pilot-wave theory, these tiny particles are guided by a tiny wave that surrounds them. It's kind of like a boat that's being guided by a wave in the water.
So imagine that the electron is like a boat, and the wave is the water it's moving through. The boat is being guided by the wave, which determines where it goes and how it moves.
But wait, there's more! The wave itself is also affected by the presence of other particles in the area. This means that the position and movement of other particles can influence where the electron goes!
This theory is still being studied and debated by scientists today, but it's really interesting to think about how even the tiniest of things around us are guided by waves and affected by the things around them. Pretty cool, huh?
