How Does 10 Terrifying Theories About What's Outside The Universe Work?

Imagine the universe is like your favorite toy box, but there might be other toy boxes outside it, and we don’t know what’s in them!

The Toy Box Outside

One idea says our universe is just one of many, like a big cosmic neighborhood. Each universe could have its own rules, maybe some have gravity that works backward or colors you can't see with your eyes. It's like having different toy boxes where each one has special toys only you can play with if you know the secret.

The Universe Was Born from Something Bigger

Another theory says everything started from an incredibly tiny dot, and then it exploded into what we now call the universe, kind of like when a balloon pops, but way bigger. Some people think there might be even more stuff outside that big pop, like a giant blanket covering all the toy boxes.

The Universe Is Like a Bouncing Ball

Some scientists say our universe could be bouncing between different states, like how a ball bounces up and down when you throw it. Maybe after it stops bouncing, there's something new waiting to happen!

These ideas are just fun ways to imagine what might lie beyond the toy box we call the universe. Imagine the universe is like your favorite toy box, but there might be other toy boxes outside it, and we don’t know what’s in them!
