The Implications of Time Travel and the Fate of Celebrities

Imagine the concept of a time traveler who could go back in time and kill a celebrity from fifty years ago. But what then? Would the victim disappear gradually, or would their body and all its contributions to the world vanish with immediate effect?

The theory of relativity, introduced by Albert Einstein in 1905, helps us understand the nuances of such a scenario. In this framework, the time traveler’s universe and the current timeline where the celebrity is alive are two separate branches of time.

The Two Timelines Hypothesis

Let's assume that the time traveler makes a decision to kill a celebrity in the past. From the perspective of the traveler's timeline, the decision would be enacted, resulting in immediate death. However, from the perspective of the current timeline, this decision does not exist. This creates a unique situation where the traveler's timeline diverges from the current one.

From the current timeline's perspective, if the story of the celebrity's untimely death is of interest, the traveler's universe could 'pipe in' as a fictional story. This could manifest as a movie, comic book, TV show, video game, or other narrative formats. In this alternate reality, the celebrity would have a different story, one that includes their earlier death.

The Relativity of Time and Divergent Universe

However, if the time traveler understands the concept of relativity and non-shared timelines, the unfolding of events in their universe would be entirely autonomous. They cannot dictate how things play out in the existing timeline. The existing timeline is not impacted by the traveler's actions unless they are aware of and communicate the changes back.

If the time traveler is unaware of the relative nature of time and the existence of non-shared timelines, several scenarios could unfold:

Gradual Disappearance

In this scenario, the body of work created by the celebrity would be altered. The contributions would appear to be from fifty years ago, reflecting a gradual disappearance. The celebrity's life could be time-shifted, meaning their earlier life and its contributions would be seen as part of a different time period.

Absence of Influence

The more dramatic possibility is that time itself is rewritten, completely eliminating all traces of the celebrity's influence. The culture and existence would no longer bear any resemblance to the original timeline. Upon returning to the current timeline, the traveler would find a world that is vastly different from the one they left behind.

Discovery of Alternate Realities

Another scenario could involve the traveler accidentally discovering articles, news reports, or even media content that suggests the celebrity faked their death, activists lied about the celebrity, or that their parents were members of a cult. These discoveries could validate the traveler's belief that the celebrity is still alive, leading to a failed mission.

Implications and Branching Histories

These various scenarios highlight the complexity and unpredictability of time travel. The outcome is not predetermined, but rather left to the traveler's decisions and actions. In a shared timeline, any attempt to alter the past would result in the creation of a new branch. If the traveler's actions are negated, they would be isolated in a divergent timeline, experimenting and trying to find a way to align with the original timeline.

The traveler would have to navigate these branching histories, understanding the implications of their actions on both the past and the present. Time travel, in this context, is not just about altering the past; it is about rewriting and understanding the interconnectedness of multiple timelines.

However, the real question is: Can the traveler find a way to manipulate time without creating too many temporal paradoxes? Time travel, in both theory and fiction, remains a fascinating and complex concept. The potential for multiple outcomes and divergent histories underscores the mystery and allure that continues to captivate the imagination of scientists, philosophers, and the general public.
