Mountains' secret to pace your age that beaches don't

The peculiar truth in simple terms
Time doesn’t tick equally everywhere, it varies with locations. Higher altitude means slightly weaker gravity that results in slightly faster time. Mountains “age” you a whisper faster than beaches.

Gravity is a brake on time
Picture gravity as a soft brake. Stronger gravity presses harder, slowing every process—including clocks and biology—a tiny bit. Weaker gravity eases off, and time runs a touch quicker.

Proof from stacked clocks
Scientists placed ultra-precise atomic clocks about 1 meter apart; the higher one ticked faster. The difference is tiny (trillionths of a second), but real and measurable.

Mountains vs beaches (how big is it?)
Live years on a mountain and you’ll end up fractions of a second “older” than a sea‑level twin. You won’t feel it—only precision clocks can tell—but the direction is clear.

How gravity slows aging (for the nerds)
Einstein’s general relativity says mass curves spacetime. Deeper in a gravity well (closer to a massive body), spacetime is more curved, so the rate at which time passes is reduced. Move higher (weaker gravity), and that curvature eases—time speeds up a hair.

Everyday relevance
GPS satellites run in weaker gravity and move fast; without relativity corrections, maps would drift kilometers per day. Finance, telecom, and power grids rely on this same precise, corrected time
