Einstein's General Relativity Time Dilation — Live Your Head Ages Faster Confirmed by Atomic Clocks GPS Satellites Correct 38μs Daily Patent Pending Einstein's General Relativity Time Dilation — Live Your Head Ages Faster Confirmed by Atomic Clocks GPS Satellites Correct 38μs Daily Patent Pending
Einstein Time Dilation Timepiece

Time moves differently for your head and your feet.

This is not a theory. It is happening in your body right now, every second of every day. Now you can watch it.

How it works

Two clocks.
One body.

Both watches show real current time. But the head watch runs fractionally faster — accumulating a gap that grows every second you're alive.

⏱
Live Dilation Counter
Watch the nanoseconds accumulate in real time. The gap grows every second you're alive.
🧬
Your Lifetime Gap
Enter your age and discover exactly how much older your head already is than your feet across your entire life.
📍
GPS Altitude Aware
The higher you are, the faster time moves. GPS detects your elevation and adjusts the dilation rate live.
🌍
Landmark Comparisons
Your gap vs. GPS satellite corrections, Mt. Everest, the speed of light, and an 80-year human lifespan.

The Science

Proven by
atomic clocks.

In 2010, physicists at NIST confirmed gravitational time dilation across just 33 centimeters — less than your forearm. This app shows you your personal piece of that experiment, happening right now.

Δt = (gh/c²) × t
g = gravitational acceleration (9.8 m/s²)
h = height difference (head to feet)
c = speed of light (299,792,458 m/s)
t = elapsed time
38 μs GPS satellites correct for time dilation every single day
33 cm Height separation at which NIST confirmed the effect in 2010
~500 ns How much older your head is than your feet over an 80-year lifetime
1915 Year Einstein published General Relativity and predicted this effect
