ELI5: Explain Like I'm 5

N-dimensional space

So, you know how we live in a 3-dimensional world? There's height, width, and depth.

Well, imagine there could be even more dimensions. Like, we could add another dimension called "time" which would make it 4-dimensional.

Now, with n-dimensional space, n just means any number of dimensions. It could be 4, 5, 6, or even more!

So, if we were to imagine n-dimensional space, we would just have to add more dimensions to our 3-dimensional world.

It might be hard to picture, but just think of it like adding more directions to move in. Instead of just up and down, left and right, and forwards and backwards, there could be even more ways to move around.

Scientists and mathematicians use n-dimensional space to help solve complex problems and understand how things work. It's kind of like a puzzle that they have to figure out.
