Is the ending of interstellar physically possible?

The excerpt supplied contains only production details: the film’s basic plot premise, cast, and background on development and scientific consultation. It does not describe the ending scene or the physics depicted therein. Consequently, with the given evidence, we cannot assess whether the conclusion of Interstellar aligns with real-world physics. Any claim about the ending’s physical possibility would require additional material—such as a plot synopsis, scientific analysis, or statements from the film’s creators—that is not present in the source. Therefore, based solely on the provided data, we must note that the question remains unanswered.
