The following five timelines show the geologic time scale to scale. The first shows the entire time from the formation of the Earth to the present, but this gives little space for the most recent eon. The second timeline shows an expanded view of the most recent eon. In a similar way, the most recent era is expanded in the third timeline, the most recent period is expanded in the fourth timeline, and the most recent epoch is expanded in the fifth timeline.

(Horizontal scale is millions of years for the above timelines; thousands of years for the timeline below)

Big Bang occurs when ordinary space and time develop from a primeval state (possibly a false vacuum) described by a quantum theory of gravity or "theory of everything". Infant universe cools as it begins expanding outward. The universe is almost completely smooth, as quantum variations begin to cause slight variations in density. The expansion decelerates. Recombination; electrons combine with nuclei to form atoms, mostly hydrogen and helium, ordinary matter particles decouple from radiation. First stars. Formation of HD 140283, the "Methuselah star", seemingly more than 14 Ga ago. Formation of the star SMSS J031300.36−670839.3. Reionization begins, with certain wavelengths of light absorption by neutral hydrogen making Gunn–Peterson troughs. The resulting ionized gas (mainly free electrons) in the intergalactic medium causes some light scattering, but with much lower opacity than before recombination due to cosmic expansion and gas clumping into galaxies. Formation of galaxies. HD1 galaxy forms. Earliest quasars. The exoplanet PSR B1620-26 b forms. It is a gas giant, the oldest observed exoplanet in the Universe, orbiting a pulsar and a white dwarf. Visual limit of Hubble Deep Field. Since (known) universe still small in size, galaxy interactions become common as larger and larger galaxies form out of galaxy merger process. Due to many being Population III stars (some Population II stars at this time); they are much bigger and hotter, and their lifespans are fairly short. Unlike later generations of stars, these stars are metal-free. SN 1000+0216, oldest observed supernova, occurs. Terzan 5 forms as a small dwarf galaxy on a collision course towards the Milky Way. The dwarf galaxy carrying the Methuselah Star is consumed by the Milky Way. Formation of the star clusters NGC 6522 and Omega Centauri.

Formation of the Gliese 581 planetary system, BX442 (oldest grand design spiral galaxy observed), globular cluster NGC 2808, red giant star Mu Cephei, and the Andromeda Galaxy. Barnard's Star (nearby red dwarf star) may have formed.

Formation of the earliest Population I stars and planetary nebulae, followed by rocky terrestrial planets, moons, asteroids and icy comets. Formation of the exoplanets 55 Cancri B, Kepler 11 c and 51 Pegasi b. A galaxy collides with the Milky Way, giving rise to the so-called Gaia Sausage population of stars. Formation of Gliese 876 and its planets.

Hadean eon

Pre-Noachian era (Mars)

Pre-Tolstojan period (Mercury)

Pre-Nectarian period (Moon)

The dark-energy dominated era starts after the matter-dominated era. Formation of the open star cluster Messier 67. A primal supernova possibly triggers the formation and evolution of the Solar System. Due to accretion, many smaller planets form in orbits around the proto-Sun, some with conflicting orbits, causing the Early Heavy Bombardment to begin. Many Galilean moons may have formed at this time, including Europa and Titan. The Earth-Moon system is formed after a giant impact by the hypothetical planetoid Theia A major collision with a Pluto-sized planetoid causes the Martian dichotomy, forming Mars' North Polar Basin. The Sun enters main sequence: solar wind sweeps Earth Moon system clear of debris (mainly dust and gas).

Hadean eon

beginning of Archaean eon

Eoarchean era

Basin Groups era.

Nectarian era

Imbrian period

Formation of Kepler 438 b. Huge meteorite impact makes South Pole Aitken Basin on Moon, then huge mountain chain on lunar south limb forms. After moon forms, oldest lunar crust, formed of lunar anorthosite, differentiates from lower magmas. Earliest Earth crust probably made similarly out of similar material. Earth's crust cools enough to let oceans form. Oldest known mineral, found in the Jack Hills, Australia. Detrital zircons show presence of solid crust and liquid water. Resonance at Jupiter and Saturn's orbits moves Neptune into the Kuiper belt, causing disruption among asteroids and comets there, so the Late Heavy Bombardment batters the inner Solar System (possibly). Origin of life on Earth. Earliest known life forms: unusually high amounts of light isotopes of carbon, a common sign of life, found in mineral deposits aged 4.25 Ga located in the Jack Hills of Western Australia. Herschel Crater is formed on Mimas, a moon of Saturn. A meteorite impact on Mars makes Hellas Planitia, the largest unambiguous structure on planet. Acasta Gneiss of Northwest Territories, Canada, oldest known rock. Anseris Mons, lonely massif in Mars southern highlands, at the northeast edge of Hellas Planitia uplifted in the wake of a meteorite impact. Nectaris Basin forms from a large impact event causing ejecta from Nectaris to form the upper part of a densely cratered lunar highlands. Tolstoj (crater) forms on Mercury.

Evidence for hydrothermal vent microbes. Biogenic graphite in metasedimentary rocks aged 3.7 Ga discovered in Western Greenland. Weathering of land affects ocean chemistry. Alba Mons forms on Mars, largest volcano by area. Possible formation of Vaalbara supercontinent; oldest cratons on Earth (like the Canadian Shield, East European Craton and Kaapval craton) begin growing due to crustal disturbances along continents coalescing into Vaalbara – Pilbara Craton stabilizes. Makhonjwa Mountains uplifts on east edge of Kaapval craton, as these are the first mountains in Africa. Narryer Gneiss Terrane stabilizes: gneisses are "bedrock" for the formation of Yilgarn Craton in Australia – noted for survival of the Jack Hills where the oldest mineral, a zircon, was found. Lifetime of Last universal common ancestor, Bacteria and Archaea split. Varieties of Eubacteria begin to radiate out globally.

Paleoarchean era

Mesoarchean era

Amazonian period (Mars)

Eratosthenian period

Microbial mat fossils and signs of life on land. in Western Australia. Stromatolites. In the "Amazonian period" on Mars the atmosphere thins to its present density when groundwater at its upper crust (megaregolith) begins to freeze, forming a thick cryosphere above a deeper liquid water zone. Impact cratering becomes the main geological force on the Moon. Onverwacht series form, containing some of the oldest microfossils which are mostly spheroidal, carbonaceous and algae-like. Formation of the continent Ur, covering between 12 and 16% of current continental crust. Formation of the Limpopo Belt. Gneiss and greenstone belts in the Baltic Shield laid down in the Kola Peninsula, Karelia, and northeast Finland. Formation of Kenorland, based upon Baltic shield core. Breakup of the continents Vaalbara and Ur as the latter becomes part of the supercontinent Kenorland. Possible Cyanobacteria (photosynthesis). Photosynthesizing cyanobacteria appear, using water as reducing agent, thereby making oxygen as waste. Oxygen initially oxidizes dissolved iron in the oceans, creating iron ore – over time, oxygen concentration in the air rises, acting as a poison for many bacteria. As the Moon is still very close to Earth and causes tides 1,000 feet (305 m) high, Earth is continually wracked by hurricane-force winds – these extreme mixing influences are thought to stimulate evolutionary processes. Microbial mats successfully form the first reef-building communities on Earth in shallow warm tidal pool zones. Stabilization of cratons. Sterane biomarkers possibly indicate the first eukaryotes. Possible largest crater on earth near Maniitsoq, Greenland.

Terrestrial fungi. First Protozoa appear. As creatures like Paramecium, Amoeba and Melanocyrillium appear, first animal-like cells become distinctive from plants – rise of herbivores in the food chain. Breakup of Rodinia, Sturtian glaciation begins, one of at least three episodes of Snowball Earth – great ice sheets cover most of planet stunting evolution of animal and plant life – survival based on small pockets of heat under ice. Volcanism on Venus practically stops.

Worm trail impressions – putative "burrows" under stromatolite mounds of uneven width and tapering, making biological origin difficult to defend – structures imply simple eating behaviours. Rifting of Rodinia comes to an end: formation of new superocean Panthalassa as the previous Mirovia ocean bed closes. Demosponges appear. Pannotia supercontinent forms, bordered by Iapetus and Panthalassa oceans, then breaks up into Laurentia, Gondwana, Angaraland and Baltica. Accumulation of atmospheric oxygen allows for formation of the ozone layer: prior to this, land-based life would have required other chemicals to attenuate ultraviolet radiation enough to allow colonization of land.

Return of the Great Comet of 1861. The 639-year-long performance of As Slow as Possible (begun in 2001) is scheduled to finish. 1950 DA has a 1 in 2,600 (0.039%) chance of colliding with the Earth. The last time capsule out of four at the Helium Centennial Time Columns Monument is scheduled to be opened. The Longplayer composition is set to finish.

Completion of the Time Pyramid in Wemding, Germany. Gamma Cephei replaces Polaris as the North Star. The Westinghouse Time Capsules from the years 1939 and 1964 are scheduled to be opened. The last Expo '70 Time Capsule from the year 1970, buried under a monument near Osaka Castle, Japan is scheduled to be opened. Opening of the Crypt of Civilization.

Antares likely goes supernova. Vega becomes the northern pole star. North celestial pole moves far from present North Star, causing summer and winter to occur on opposite sides of Earth's orbit and summer and winter constellations to switch. The Chernobyl Exclusion Zone returns to normal levels of radiation. The Arecibo message reaches its destination. Ross 248 passes within 3.024 light-years of Earth, becoming the closest star to the Sun. Expected descent of the KEO time capsule, assuming it is launched. The length of the day increases by one SI second. Presently used Computus will give Paschal Full Moon at new moon. Alpha Centauri passes the Sun and continues toward Lynx. Present constellations become unrecognizable. The Hebrew calendar is out of sync with the seasons.

The Gregorian Calendar is out of sync with the seasons. Kamaʻehuakanaloa (formerly Lōʻihi) becomes a new volcanic island. WR 104 likely explodes, if not sooner. Badlands National Park erodes completely. Several supervolcanoes erupt. The Strait of Gibraltar closes. The Mediterranean Sea dries up.

Technetium-99 produced today ceases to be a danger. Betelgeuse goes supernova, if not sooner. Meteor Crater wears away. Gliese 710 passes through the Oort Cloud. A day on Earth is one minute longer than it is today. Without maintenance, Mount Rushmore erodes into unrecognizability. The LAGEOS satellites' orbits decay. Several kilometre-size asteroids or comets are on a collision course with Earth. The Afar Depression and the East African Rift become a new sea, splitting Africa.

Phobos collides with Mars, if not sooner. The Mediterranean Basin closes. The island of Hawaii submerges. Iodine-129 and Neptunium-237 in nuclear waste decay away.

A day on Earth is one hour longer than it is today. Different continents from today due to splitting and coalescence. Possible new supercontinent. The Sun completes several orbits around the Milky Way.

The atmosphere becomes a "moist greenhouse", resulting in a runaway evaporation of the oceans, causing plate tectonics to stop completely, if not already stopped sooner. Eukaryotic life dies out on Earth due to carbon dioxide starvation. The Moon is moved too far away from Earth to stabilize its axial tilt. The Earth's oceans evaporate. All unicellular life goes extinct. Triton falls through Neptune's Roche limit. Andromeda–Milky Way collision. The Sun exhausts its hydrogen supply and becomes a red giant. The Sun achieves its maximum radius 256 times its present-day value.

The Sun becomes a white dwarf. Presently existing uranium and rhenium-187 decay away.

The white dwarf Sun fades away. The Local Group coalesces. Presently existing thorium decays away.

Galaxies outside Local Supercluster no longer visible (if dark energy prevails). Proxima Centauri ceases to be a main-sequence star.

Star formation ends. The Degenerate Era starts.

Nuclear fusion ceases (if not sooner). The Sun becomes a black dwarf.

Vanadium-50 decays.

Tungsten-180, Europium-151, Molybdenum-100, Neodymium-150, and Tellurium-130 decay.

Zirconium-96, Bismuth (209), Calcium-48, and Cadmium-116 decay.

Selenium-82 decays.

Barium-130, Germanium-78, Xenon-136, and Krypton-78 decay.

Xenon-124 decays.

Tellurium-128 decays.

Only solitary objects remain in the universe by this point.
