Immortal

"Immortal" refers to the state of never dying or living forever. In literature and philosophy, it can describe beings, entities, or concepts that are eternal and unaffected by time or aging. While humans are mortal and will eventually die, immortality implies an existence that persists endlessly. In science fiction, immortality is often explored through theories like advanced technology, biological enhancements, or supernatural forces. It raises questions about identity, ethics, and the nature of life, highlighting the contrast between finite human lives and the concept of endless, unending existence.
