The atlas · humanity's ages
Every leap, in order.
~300,000 years of one species, compressed to the moments that actually changed the ceiling on what was possible. Deep history has no clean before/after number to cite, just a date and why it mattered. The current age does have numbers, tracked live below, the same Kardashev scale and cost-to-orbit data already on /progress.

Homo sapiens emerges
Fossil evidence from Jebel Irhoud, Morocco, pushed the earliest known Homo sapiens back to roughly 300,000 years ago, about 100,000 years earlier than the previous consensus. Everything below is what one species did with the time since.

Agricultural Revolution
Plant and animal domestication began independently in several regions, starting with the Fertile Crescent. Farming let a fixed area of land support far more people than foraging, which is what made cities, specialization, and surplus-funded institutions possible at all.

Writing invented
Sumerian cuneiform, the earliest writing system with strong evidence, emerged in Mesopotamia for administrative record-keeping. This is the point knowledge stops being bounded by one person's memory or one generation's oral transmission.

Gutenberg's printing press
Movable-type printing collapsed the cost of copying a text by roughly two orders of magnitude. Literacy, and later the Scientific Revolution and Reformation, were downstream of information suddenly being cheap to reproduce.

Watt's steam engine patented
James Watt's separate-condenser design made steam power practical beyond pumping water out of mines, and is conventionally treated as the starting gun for the Industrial Revolution: for the first time, human and animal muscle was no longer the ceiling on mechanical work.

Practical incandescent light bulb
Edison's long-lasting carbon-filament bulb made electric lighting commercially viable, and electrification followed over the next five decades: light, then motors, then an entire grid most of the modern economy still runs on.

First powered flight
The Wright Flyer's 12-second, 120-foot flight at Kitty Hawk was the first sustained, controlled, powered flight by a heavier-than-air craft. Sixty-six years later a much faster-moving version of the same lineage put people on the Moon.

Trinity test — nuclear age begins
The first detonation of a nuclear weapon, in the New Mexico desert, opened a civilizational-scale energy source and a civilizational-scale risk in the same instant. Every energy-abundance conversation since carries this in the background.

Sputnik — the Space Age begins
The Soviet Union's Sputnik 1 was the first artificial satellite. It weighed 184 pounds and did nothing but beep, and it still triggered a full civilizational reorientation of resources toward space within a decade.

Moon landing
Apollo 11 put the first humans on a surface other than Earth's, 66 years after the Wright brothers' first 12-second flight. No human has gone farther than low Earth orbit since 1972 — the fastest part of the space curve was already behind us by this point, a real caution against assuming any curve keeps compounding.

World Wide Web goes public
Tim Berners-Lee published the first website and made the WWW protocol publicly available from CERN. The internet-adoption curve tracked live on /signals starts counting from here.

The current age, tracked live
No date on this one yet. It's still being written.
Kardashev scale (energy civilization type)
0.728
1973 → 2026, 4%
How much of a star’s available energy a civilization has learned to harness, on Kardashev’s Type 0-to-3 scale. Type 1 is full use of everything a home planet receives. This is the closest thing to a single number for "how advanced is humanity," and by design it does not care about GDP or population — only energy captured and put to use.
Cost to reach orbit
$2,720
1981 → 2026, 22.1× lower
USD per kilogram to low Earth orbit. This is the actual enabling metric behind Mars colonization — not a countdown or a mission tracker, but the cost curve that has to keep collapsing before Mars is anything other than a demonstration flight. Reusability is the whole story: the Space Shuttle was marketed as reusable and was still more expensive per kilogram than the expendable Saturn V that preceded it.
Healthy life expectancy (HALE)
64 yrs
2000 → 2019, 8%
Years a newborn can expect to live in good health — distinct from life expectancy above, which counts every year alive regardless of health. This is the real longevity-progress metric: adding years to a life is easy to overstate as progress if most of those years are spent sick. HALE only rises when disease and disability compress, not just when death is delayed.
source and methodology on /progress
The Moon landing is the honest caution on this page: 66 years from first flight to the Moon, then 55 years and counting with no human past low Earth orbit. A curve compounding does not mean it keeps compounding. /frontier tracks who is disclosing real capital toward restarting it now.
