Timeline paradox

A timeline paradox occurs when changes made to the past create inconsistencies or contradictions in the timeline, often called "causal loops." For example, if someone travels to the past and prevents their grandparents from meeting, it could mean they were never born, which clashes with their efforts to travel back. These paradoxes highlight challenges in understanding cause and effect across different points in time, especially if time travel were possible. They raise questions about the nature of causality and whether altering the past could create logical or reality-breaking scenarios.
