Why do we not have spin greater than 2?

We don’t have spin greater than 2 because it’s like trying to twist a rope that can only twist so much before it breaks.

Imagine you're holding a jump rope. When you swing it around, it spins, this is like spin 1. If the rope has two people on each end, and they both spin in the same direction, it's like spin 2. But if you tried to twist that rope more than twice at once, it would just tangle up or snap, there’s a limit to how much something can twist.

Now think of particles as tiny balls with invisible ropes attached to them. These ropes spin around, and the number of twists they can make is their spin. Scientists have found that most basic building blocks in nature only need to twist up to two times, no more, no less. It’s like how a toy car has four wheels, you don’t need six or eight for it to roll smoothly.

So far, everything we’ve seen in the universe fits with this rule, and if there were particles with higher spin, they’d be like ropes twisted way beyond their breaking point. We just haven’t found them yet!
