The universe is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. You may think it's a long way to the chemist, but it's nothing compared to space.

Let me try to explain. The universe is so big that it's hard to wrap your head around it. Just imagine a number. Any number. Now multiply it by itself. That's the size of the universe. And it's not just a number. It's a number with a lot of zeros after it.

The universe is so big that even the most powerful telescopes can only see a tiny fraction of it. And what we can see is mostly empty space. The stuff that we can see, like stars and galaxies, is spread out so thinly that if you took all the matter in the observable universe and spread it out evenly, it would barely cover the surface of a tennis ball.

And the universe is not just big, it's also old. Really old. The universe is estimated to be about 14 billion years old. That means that the light from some of the furthest galaxies has taken billions of years to reach us.

But the universe is not just old, it's also expanding. Every day, the galaxies are getting further and further apart. In fact, the universe is expanding so fast that one day, it will be infinitely old and infinitely big.

We often talk about the size of the universe in terms of the order of planets, solar system, galaxy, and supercluster. But what's beyond that?

Let's start with the basics. Our solar system consists of the sun and all the planets and other bodies that orbit around it. Our galaxy, the Milky Way, consists of our solar system plus billions of other stars and their planets. And there are billions of other galaxies in the universe.

So, when we talk about the size of the universe, we're really talking about the size of all the galaxies in it. And that is mind-bogglingly big.

But it gets even bigger. Because not only are there billions of galaxies, but they're also constantly moving away from each other. In fact, the universe is expanding.

So, the universe is not only big, but it's also constantly getting bigger. And we have no idea how big it will eventually become.

So, what's beyond the order of planets, solar system, galaxy, and supercluster? 

The answer is: we don't know. 

The universe is so big and so constantly expanding that it's beyond our ability to comprehend.

But that doesn't mean we shouldn't try. The universe is an amazing place, and the more we learn about it, the more awe-inspiring it becomes.
