Detailed logarithmic timeline
This timeline shows the whole history of the universe, the Earth, and mankind in one table. Each row is defined in years ago, that is, years before the present date, with the earliest times at the top of the chart. In each table cell on the right, references to events or notable people are given, more or less in chronological order within the cell.
Each row corresponds to a change in log of about 0.1. The dividing points are taken from the R′′20 Renard numbers. Thus each row represent about 21% of the time from its beginning until the present.
The table is divided into sections with subtitles. Note that each such section contains about 68% of all the time from the beginning of the section until now.

Future
A logarithmic timeline can also be devised for events which should occur in the future, barring unforeseen circumstances and assuming that we can extrapolate into the future based on our science.Time interval | Event |
1 – 10 years | |
10 – 100 years | Global warming. Year 2038 problem and Year 2106 problem |
100 – 1000 years | Consumption of fossil fuels much lower than at present |
1000 – 10 ka | Opening of the Crypt of Civilization. Summer and winter constellations switch, north celestial pole moves far from present North Star |
10 ka – 100 ka | Presently used Computus will give Paschal Full Moon at new moon. Alpha Centauri passes the sun and continues toward Lynx. Present constellations become unrecognizable. Hebrew Calendar out of sync with seasons. |
100 ka – 1 Ma | Gregorian Calendar out of sync with seasons. Several supervolcanoes erupt. Strait of Gibraltar closes, Mediterranean Sea dries up. |
1 Ma – 10 Ma | Technetium-99 produced today ceases to be a danger Gliese 710 passes through the Oort Cloud. Several kilometre-size asteroids or comets on collision course with Earth. The Afar Depression and the East African Rift become a new sea, splitting Africa. |
10 Ma – 100 Ma | Mediterranean basin closes. Iodine-129 and Neptunium-237 in nuclear waste decay away. |
100 Ma – 1 Ga | Different continents from today due to splitting and coalescence. Possible new supercontinent. Sun completes several orbits around the Milky Way |
1 Ga – 10 Ga | Hotter sun makes land too hot for life. Oceans evaporate. Andromeda–Milky Way collision. Sun becomes a red giant |
10 Ga – 100 Ga | Sun becomes a white dwarf Presently existing uranium and rhenium-187 decay away. |
100 Ga – 1 Ta | White dwarf Sun fades away. Local Group coalesces. Presently existing thorium decays away. |
1 Ta – 10 Ta | Galaxies outside Local Supercluster no longer visible. Proxima Centauri ceases to be a main-sequence star. |
10 Ta – 100 Ta | Star formation ends. Degenerate Era starts. |
100 Ta – 1 Pa | Nuclear fusion ceases. Sun becomes a black dwarf. |
1 Pa – 10 Pa | Planets fall or are flung away from their stars. |
10 Pa – 100 Pa | |
100 Pa – 1 exaannus | Vanadium-50 decays. |
1 Ea – 10 Ea | Tungsten-180, Europium-151, Molybdenum-100, Neodymium-150, and Tellurium-130 decay |
10 Ea – 100 Ea | Zirconium-96, Bismuth, Calcium-48, and Cadmium-116 decay |
100 Ea – 1 zettaannus | Selenium-82 decays |
1 Za – 10 Za | Barium-130, Germanium-78, Xenon-136, and Krypton-78 decay |
10 Za – 100 Za | Xenon-124 decays |
