The idea of changing the future by altering specific events or influencing the birth of individuals can have far-reaching consequences that extend to the past, present, and future. The precise outcome would depend on the rules and mechanics of time travel in the hypothetical scenario.
In many time travel narratives, the notion of changing the past or future often involves the concept of a "butterfly effect." According to this concept, even small changes in the timeline can have cascading effects and potentially result in significant alterations to subsequent events. These changes can impact not only the immediate future but also the past and other potential timelines.
If someone were to intentionally manipulate events or alter the timing of certain occurrences, it could lead to a ripple effect throughout history. The changes may create a new set of circumstances, influencing the decisions and actions of individuals, which in turn can reshape the course of events. This could result in a chain reaction of cause and effect, ultimately leading to a different future than the one originally anticipated.
However, the exact nature of the ripple effect and its impact on time, alternate timelines, and other events is largely speculative and subject to interpretation. Different fictional works and theories present varying views on the nature and consequences of time travel. Some propose that changes in the timeline create a new branch or alternate reality, while others suggest that the changes would overwrite the existing timeline.
It's worth noting that the concept of time travel and its ramifications are currently matters of speculation and debate. There is no empirical evidence to support the existence of time travel or its effects on past, present, or future events. As a result, the specific consequences of changing the future through time travel remain speculative and are primarily explored in works of fiction.
