The conformal cyclic universe theory is like a never-ending game that keeps resetting itself.

Imagine you're playing with building blocks, you stack them up high, and then poof! They all fall down, and you start over. That’s kind of what the conformal cyclic universe theory says happens to the universe: it expands for a long time, everything cools off, and then it starts again from the beginning, like a brand-new game.

Think of each "game" as one cycle of the universe. In the first cycle, the universe begins with a big bang, it’s hot, bright, and full of energy. Over time, everything spreads out, stars form, planets appear, and eventually, everything starts to slow down.

Then, like your blocks falling apart, the universe gets really cold and empty. But instead of ending, it resets, not by magic, but by a kind of reshaping. It’s like the universe takes off its old clothes and puts on new ones, ready for another big bang.

This theory helps scientists think about how the universe might have started, and maybe why it keeps going forever!
