Part 6/8:
As we explore the implications of time dilation, we encounter fascinating paradoxes. The twin paradox exemplifies this: one twin travels at near-light speed while the other stays on Earth. Upon reunion, the traveling twin is younger than the sibling who remained behind, showcasing time's relative nature regardless of their identical starting point.
Another thought-provoking situation is the grandfather paradox, which envisages a time traveler who prevents their grandparents from meeting, thus thwarting their own existence. Such scenarios suggest that time travel could lead to contradictions that upend causality.
