The one-star universe

There is this star who resides in a small universe, who one day feels like leaving that universe.

In order to make the universe feel better for its departure, the star says these to the universe:

"Do you know, in the Solar System, the Planet Earth is either slightly or far bigger than these planets - Venus, Mars, Mercury, and Pluto, size in ascending order?"

"Having said that, do you know, however, these planets are far bigger than the Planet Earth in the Solar System - Jupiter, Saturn, Uranus, and Neptune? We can even fit about 1400 Earths inside the Jupiter!"

"Having said that, do you know, compared to the Sun, however, the Jupiter is about 980 times smaller?"

"Having said that, do you know, out of our Solar System, there is a very big universe, and all the stars in it, like Sirius, Pollux, Arcturus, size in ascending order, are much much bigger than the Sun?"

"Having said that, do you know, however, even these humongous stars are simply pale in comparison to some of the other stars in the universe like: Rigel, Aldebaran, Betelgeuse, Antares, size in ascending order, where Antares is the 15th brightest star in the sky and is more than 1000 Light Years away from the Planet Earth?"

"So you see, my dear universe, I am just such a tiny little dot in the sky. Please don't be sorry if I leave you."

The universe replies sadly:

"Yeah sure, those stars are indeed very big, and of course, the creator of all of them can only be the biggest."

"But you have to understand, a star can only be bigger in comparison to a smaller one. If you are the one and only star in a universe who has been illuminating it all its life, and the universe can only be a universe because of your presence, how can you say you are not big enough for that universe?"

"No, you have no idea, I think."
