The world you know is only the newest layer. Scroll down through decades, empires, writing, farming and human origins. The farther you travel, the greater the distance between moments becomes.
More than eight billion people share a planet connected by satellites, global networks, aircraft and instant communication. Artificial intelligence is becoming part of everyday life. This is the familiar world — and the point from which every PastPlanet journey begins.
The Berlin Wall falls and the political map of Europe begins changing at extraordinary speed. Within two years the Soviet Union will dissolve, ending the geopolitical structure that shaped much of the second half of the twentieth century.
Apollo 11 lands on the Moon. For the first time, humans stand on another world. The achievement is technological, political and symbolic: a species that evolved on Earth can now physically leave it.
The Second World War ends after unprecedented destruction. The United Nations is founded, colonial empires begin unraveling more rapidly, nuclear weapons alter global strategy and two superpowers emerge into confrontation.
European rivalries erupt into the First World War. Railways, factories, artillery, aircraft and mass mobilization transform warfare. Empires collapse, borders shift and political consequences continue shaping the century that follows.
Events that once felt far apart begin to compress. Keep scrolling. The familiar world starts disappearing.
Industrialization accelerates first in Britain and then spreads. Steam power, mechanized production and new transport systems begin changing how people work, travel, build cities and consume energy.
Columbus reaches the Caribbean, accelerating sustained contact between Europe, Africa and the Americas. Exchange follows — along with conquest, forced migration, disease and ecological transformation on a planetary scale.
A devastating plague pandemic moves through interconnected trade routes across Eurasia and North Africa. Entire communities are transformed as mortality changes labor, economies, institutions and everyday life.
Temüjin is proclaimed Genghis Khan. The empire built by him and his successors will become the largest contiguous land empire in history, reshaping politics, trade and communication across Eurasia.
The deposition of Romulus Augustulus becomes the traditional marker for the end of the Western Roman Empire. Roman institutions do not simply vanish — and the Eastern Roman Empire continues for centuries.
Julius Caesar is assassinated in Rome. The Roman Republic enters another phase of civil conflict that ultimately leads to Augustus and the imperial system that will dominate the Mediterranean world.
We are now moving beyond familiar political history. Each screen represents increasingly larger spans of time.
Monumental states and dense urban societies flourish across several regions. Egypt builds enormous pyramids, Mesopotamian cities expand and the Indus civilization develops sophisticated urban centers.
Some of the earliest known writing systems appear in Mesopotamia, with early Egyptian writing developing in roughly the same broad period. Information can now survive beyond a speaker, a lifetime and eventually an entire society.
Farming and animal domestication develop independently in different parts of the world over thousands of years. Some communities become increasingly sedentary, transforming food production, population density and eventually the possibilities for towns and states.
There are no chronicles to read now. The story survives in archaeology, genetics, landscapes, tools and bones.
Major waves of Homo sapiens expansion beyond Africa reshape the distribution of our species. The chronology is complex and earlier movements occurred, but over tens of thousands of years humans reach increasingly distant regions of the planet.
Fossils in Africa show combinations of traits associated with early Homo sapiens by roughly this period. Our species did not appear in a single instant: human origins were a long, branching evolutionary process.
Recorded history now occupies only a tiny fraction of the distance above us.
Stone artifacts from Lomekwi in Kenya date to about 3.3 million years ago. They are older than the earliest widely accepted fossils assigned to the genus Homo, suggesting toolmaking has deeper roots than once assumed.
Fossils from roughly six to seven million years ago include candidates for some of the earliest known hominins. Their exact relationships remain debated, but by this point we are approaching the deep evolutionary roots of the human branch.
Seven million years feels unimaginably distant. For Earth, it is recent history. Beyond humanity lie dinosaurs, ancient oceans, vanished continents and billions of years of deep time.
