She understood that the "world" she used to know was often nothing more than small planets among the Stellaris. Earth, as a planet, as the "world" where humans live, is already very large. However, the star in the Solar System is 1.3 million times its size; and the huge Sun is just as insignificant and unnoticeable within the larger Milky Way Galaxy, among which there are approximately 100 billion to 400 billion such stars…
Earth is as tiny as a grain of sand compared to the Solar System;
And the Solar System is an insignificant speck of dust compared to the Milky Way Galaxy;
So is the Milky Way Galaxy large? Definitely not, because beyond it lie even larger cosmic structures, such as the Local Group, the Local Supercluster, the Laniakea Supercluster, and even the Heracles - Corona Borealis Great Wall… Compared to these giant astronomical systems, the existence of the Milky Way Galaxy is like a drop in the ocean, utterly insignificant.
