De Broglie-Bohm theory, also known as pilot wave theory, is a way to understand how particles (like electrons or atoms) move through space. Imagine you and a friend are playing a game of tag, and you both start running around a playground. If you're running really fast, your friend might not know exactly where you are at every moment.
In the same way, particles can move very quickly and be very hard to track. But de Broglie-Bohm theory says that each particle is guided by something called a "pilot wave." It's like a map that tells the particle where to go.
So when you and your friend were running around, imagine there was a little GPS device that tracked your movements and showed your friend where you were going. That's kind of like what the pilot wave does for the particle - it tells the particle where to go based on certain rules.
One of the important things about de Broglie-Bohm theory is that it doesn't rely on probabilities like other theories of quantum mechanics. In those theories, scientists can predict where particles are likely to be found, but not exactly where they will be. In de Broglie-Bohm theory, the particle's location is determined by the pilot wave.
Overall, de Broglie-Bohm theory is a way to understand how particles move through space by imagining they are guided by a "pilot wave." It's a different way to explain the behavior of the very small particles that make up our world.
