The whole of time
The entire life
of the universe.
From the first instant to the last — the Big Bang, the first light, the age of stars, the present moment, and the long darkness that comes after everything.
The Planck epoch
The first instant. Space, time and the four forces are a single thing, at a temperature beyond meaning. Our physics simply stops here.
Inflation
In far less than a trillionth of a second, space erupts — doubling over and over, at least a trillion-trillion-fold. It flattens the cosmos and freezes quantum noise into the seeds of every galaxy to come.
The quark soup
A blinding plasma of free quarks, gluons and light. Matter and antimatter annihilate — and for every billion pairs, a single particle of matter is left over. That tiny surplus is everything you will ever see.
The first nuclei
Protons and neutrons fuse into the first nuclei — hydrogen, a quarter helium, a trace of lithium. Then the universe thins too far to fuse, and the recipe is set for a billion years.
First light
The fog of plasma cools into neutral atoms and the universe turns clear. Light streams free for the first time — the oldest light there is, which we still catch today as the cosmic microwave background.
The dark ages
No stars, no light but the fading afterglow. For a hundred million years, gravity quietly draws cold hydrogen along threads of dark matter, gathering the dark toward a first dawn.
The cosmic dawn
The first stars ignite — colossal, brilliant and brief. They flood the dark with ultraviolet light, forge the first heavy elements, and die young in the first supernovae.
The age of galaxies
Stars gather into galaxies, galaxies into clusters strung along a vast cosmic web. At the hearts of the brightest, supermassive black holes blaze as quasars, while generations of stars seed space with carbon, oxygen and iron.
The Sun is born
An enriched cloud collapses; our Sun lights up and its planets sweep their orbits clear. Earth forms from the same dust — the atoms in it, and in you, forged inside dead stars.
Now. You are here.
A brief, bright window when the sky is full of stars, and something made of that stardust is here to look up and notice. The strangest fact on this page.
Andromeda arrives
The Andromeda galaxy sweeps into our own. Almost no stars actually collide, but the two unwind and merge, and the night sky burns with a second river of stars.
The long isolation
Dark energy keeps accelerating the expansion. Beyond our merged galaxy, every other group is carried over the horizon, one by one, until the sky outside goes utterly dark.
The last star dies
The gas runs out and no new stars can form. The longest-lived red dwarfs flicker out one by one. The final ember fades, and the age of starlight is over forever.
The degenerate era
Only stellar corpses remain — cooling white dwarfs, neutron stars, drifting frozen worlds. Galaxies dissolve, and if protons themselves decay, even this cold matter slowly evaporates away.
The black hole era
For an almost endless span, black holes are the only things left. One photon at a time, they bleed their mass away as Hawking radiation — the smallest first, the most massive last — each ending in a final, soundless flash.
Heat death
The last black hole has evaporated. All that remains is a thinning mist of light and stray particles, drifting toward absolute zero. Maximum entropy: nothing left that can ever change. Not a bang, but the slow, final quiet.
