Hidden sector

Ok, so you know how there are things that you can see with your eyes, like toys and trees and houses? And then there are things that you can't see, like the air or germs? Well, there is something kind of like that called a "hidden sector."

Scientists think that there might be other particles and forces in the universe that we can't see or detect with our normal tools. They call this the "hidden sector." It's like a secret place that we haven't discovered yet because we don't have the right tools.

Just like how we know the air is there even though we can't see it, scientists think that there must be something in the hidden sector because of the way other things behave. They can see the effects of this hidden sector, even if they can't see it directly.

Scientists are trying really hard to figure out what's in the hidden sector and how it affects the rest of the world. It's like a big puzzle that they are trying to solve. And someday, they might discover some amazing things that we never even knew existed!
