A human life of 80 years contains approximately 2,522,880,000 seconds — over 2.5 billion moments. That is a large number by any human measure, yet it represents 0.00000058% of the universe's current age. If the universe's history were compressed into a single year, your entire life would last about 0.18 seconds.
The Cosmic Dashboard's Human level lets you enter your birth date to see your age counted live in seconds, with a progress bar showing your position within an 80-year average lifespan. It also calculates the ratio of your age to the universe's age — typically around 1 to 10 million.
This comparison isn't meant to diminish human life — quite the opposite. The fact that conscious beings capable of measuring the universe's age exist at all, in this particular 80-year window of a 13.8-billion-year history, is itself remarkable. You are made of atoms forged in stellar cores billions of years ago, briefly organized into something that can contemplate its own cosmic scale.
