What are collisions in new regimes?

Collisions in new regimes are like when kids on a playground suddenly start playing a different game without anyone telling them.

Imagine you're at a playground with your friends. You all love to play tag, running around, chasing each other. That's the old regime, everyone knows the rules, and it's fun. But one day, some of your friends decide they want to play hide-and-seek instead. They don't tell anyone else, so when you're still running after someone, they just disappear behind a tree. It feels confusing at first because the game changed suddenly, that's like a collision in a new regime.

A new regime is when something changes unexpectedly, and everyone has to adjust quickly. In tag, you're used to running and chasing, but if hide-and-seek starts without warning, it's like the rules of the game just shifted. That’s a collision: one moment everything is normal, and the next, things are different.

It's like when your favorite toy breaks, you’re used to playing with it in one way, but now it acts differently. You have to figure out how to play with it again, which can be confusing but also exciting!
