In the vast universe, even the light of a star many times larger than The Sun would look like a tiny point after traveling a few light-years.
Suppose a light source was a point, radiating light outward. When candlelight passed through a convex lens, it was focused into a point, then radiated outward again from that point, forming the "real image" of actual light.
A mirror reflected on a plane, without any focusing process.

On the surface, it seemed easy enough to swap the positions of the two points.
Pomona seemed to see Sirius Black, a man who took darkness as his surname and the brightest star as his name. He had once shone so brilliantly.
Pomona lowered her head to look at the Batman comic in her hands. In the blink of an eye, it became Superman's Crisis on Infinite Earths.
Bruno said that because human perception was deficient, the perceived boundary of the universe stood in opposition to reality. The "world" was not equal to the "universe," and the "universe" was not equal to the "world."
Perhaps the death of stars was not so common, but the destruction of planets was commonplace. Krypton was merely one of them, and Earth was merely one of them as well.
For most people, they did not know that Krypton had been destroyed, though they knew Superman existed.
Superman's power came from Krypton's gravity, several times stronger than Earth's, just as humans could jump very high with a light spring on the
