As a subject matter expert in comic book lore and superhero narratives, I can provide an analysis of Superman's longevity based on the various interpretations of the character across different media.

Superman, a character created by writer Jerry Siegel and artist Joe Shuster, is a Kryptonian with superhuman abilities due to Earth's yellow sun. In most comic book continuities, Superman is depicted as being extremely long-lived, but not necessarily immortal. His longevity is attributed to his Kryptonian biology, which is enhanced by Earth's sunlight. However, there are several factors to consider:


1. Kryptonian Biology: Superman's alien physiology allows him to age much slower than humans, but it is not clear if he would live forever.

2. Yellow Sun: His powers and longevity are tied to the radiation of a yellow sun. If he were to be without this source of energy, his longevity might be impacted.

3. Vulnerabilities: Superman has known vulnerabilities, such as Kryptonite, which can cause him severe harm or even death.

4. Storytelling: In comic books and other narratives, the concept of immortality is often flexible and subject to change based on the needs of the story.

In conclusion, while Superman is portrayed as being incredibly long-lived, the concept of him living forever is not definitively established in the source material. His longevity is a complex issue influenced by his biology, environment, and narrative requirements.

There are strong indicators that Superman may also be immortal. Theoretically, so long as he has access to a constant source of yellow solar radiation, he will not age or die. In the continuity of the Smallville television series, it has been established that Clark Kent may live (seemingly) forever.read more >>
