This thread offers a really elegant way to think about special relativity. The key insight is that everything moves through spacetime at speed c. It's just a question of how that velocity is distributed between spatial and temporal dimensions.
When you're at rest, you're traveling through time at maximum speed (c). Start moving through space, and you "trade" some of that temporal velocity for spatial velocity, which is why time dilation occurs. Light is special only because it's massless. All of its velocity budget goes toward spatial movement, leaving none for temporal movement.
This framing makes time dilation much more intuitive than the usual "moving clocks run slow" explanation. You're not moving slower through time because of some mysterious effect. You're moving slower through time because you're now also moving through space, and your total spacetime speed is conserved.
