Matter was not equally distributed in the universe.
If a powerful Extraordinary individual were to observe a miniature singular universe from the outside, he would have noticed that the arrangement of luminous stellar bodies and planetary systems resembled an oversized sponge. There would also have been threads that chained the systems together into one huge network, having layers that composed a three-dimensional and vast universe—in sponge form, naturally.
And just like the countless gaps in sponges, massive cavities existed in the space between galaxies. Such cavities were so vast and was virtually empty vacuums where no substances existed, and even the gravity emanating from other systems were so weak that it was almost non-existent.
