THE COSMIC TIMELINE
13.8 Billion Years of History
Era I — The Primordial Universe
T + 0 seconds
The Big Bang — A singularity of infinite density
erupts into the fabric of spacetime.
T + 380,000 years
The universe cools enough for electrons to bind
with protons, creating the first atoms of hydrogen.
T + 200 million years
The Cosmic Dark Ages end as the first stars ignite,
flooding the universe with ultraviolet light.
Era II — Stellar Nurseries
T + 500 million years
Stellar Nurseries form across vast molecular clouds.
Gravity collapses hydrogen into brilliant young stars.
T + 1 billion years
Proto-stars ignite nuclear fusion at their cores.
The first generation of heavy elements is forged.
Era III — Galaxy Formation
T + 2 billion years
Galaxy Mergers reshape the cosmos.
Two spiral galaxies collide in a gravitational embrace.
T + 3 billion years
The Milky Way takes shape — 200 billion stars
spinning in a grand spiral across 100,000 light-years.
Era IV — Death and Rebirth
T + 5 billion years
Black Holes awaken at galactic centers.
Space and time are stretched beyond comprehension.
T + 6 billion years
Supernovae scatter heavy elements across the cosmos.
Carbon, oxygen, iron — the seeds of life — are born.
Era V — The Solar System
T + 9.2 billion years (4.6 Gya)
Our Sun ignites within a molecular cloud remnant.
The solar system coalesces from swirling disk of gas and dust.
T + 9.7 billion years (4.1 Gya)
Earth forms from planetesimal collisions.
A giant impact tears free the Moon from young Earth.
Era VI — The Living Earth
T + 10.1 billion years (3.7 Gya)
The first single-celled life emerges in primordial oceans.
Chemistry becomes biology on the pale blue dot.
T + 13.5 billion years (0.3 Gya)
Complex life diversifies across continents and seas.
Homo sapiens emerge — the universe observing itself.
T + 13.8 billion years — Today
We stand at this moment, looking outward,
wondering about our origin and destiny.
"We are a way for the cosmos to know itself."

COSMIC UNIVERSE TIMELAPSE
An interactive journey through 13.8 billion years
This simulation was built entirely through prompting on OMMA —
a platform where you can create anything with AI.
From a simple idea to a full cinematic experience,
OMMA turned imagination into reality.
