(FORMATION OF THE KNOWN PHYSICAL UNIVERSE)
(FORMATION OF STARS IN THE MILKY WAY GALAXY)
PRETERRAN EON (BEFORE THE FORMATION OF EARTH, SOLAR SYSTEM:
4.5 byp)
TERRAN
HADEAN EON
Formation of the Solar System and Earth, outgassing of
first atmosphere and oceans, bombardment by left-over planetisimals and
debris, volcanism and formation of first continents, evolution of first
microorganisms.
TERRAN
ARCHEAN EON

microbes) and blue-green algae, Archaean regime of continental drift.
- UNNAMED INTERSTELLAR CIVILIZATION HIE236XZE (disappeared
2-3 billion years ago)
- Overview
- Homeworld: Little is known except possible Planet Type
- Biology: Little information except possible Evoltype
- Impact on Earth's evolution: 0
TERRAN
PROTEROZOIC EON
Atmosphere changes from reducing to oxygenated, rise of
aerobic life (prokaryote and eukaryote), stromatolites common, modern
regime of continental drift, formation of supercontinent of Rodinia,
warm conditions replaced by "Snowball Earth", following that the
short-lived Ediacaran biota and the appearance of first metazoa.
- 1.45 billion years ago: The "Archivists"
released their enigmatic diamondoid information spheres. Apart from
these objects, absolutely nothing is known of the nature or origin of
this species.
- 1.1 billion years ago: The "Jacks"
a species of floaters occupying Type-J planets, appear for the first
time, but unlike many Jovian species their civilization is short-lived
and cyclical. The species disappears after a few tens of thousands of
years in space.
- 788 million years ago: The "Jacks"
re-appear after having disappeared for unknown reasons; their new
civilization collapses after 112,000 years
- THE "Halogenics" [INTERSTELLAR CIVILIZATION
HIE282RZE] (extinct 780 million years ago)
- Summary
- Impact on Earth's evolution: 0 (No evidence territory
extended to Sol System)
TERRAN
PALEOZOIC ERA
Atmospheric oxygen reaches present levels, ozone shield
screens out ultraviolet radiation and allows complex life to live in
the shallows, age of invertebrates, fish, amphibians, and finally
reptiles, life emerges from the sea to colonise the land, pteridophyte
and gymnospermous plants, mild to tropical conditions and warm shallow
seas interspersed with Ordovician and Permo-Carboniferous ice ages,
continents cluster into the supercontinent of Pangea.
- 451 million years ago: The "Jacks"
rise from dormancy and form a new civilization, which collapses after
56,000 years
- Alien object "Omicron Hygeras 152-3343 Gm-A"(appeared
400 million years ago)
- THE HOV'S'SA (vanished 312
million years ago)
TERRAN
MESOZOIC ERA
Age of archosaurian reptiles, dinosaur megafauna,
sea-reptiles, pterosaurs, ammonites, mammals small and insignificant,
conditions warm and tropical worldwide, supercontinent of Pangea breaks
up into Laurasia and Gondwana, modern corals, insects, fish and finally
flowering plants evolve
- 196 million years ago: species
HIE636MZE apparently was exterminated by a nanoswarm
of its own creation. Four of the five different alien civilizations
existing in the same galactic arm at the time of the nanoswarm (three
of which belong to the same species - HIE634MZE) attempted to design
defenses against the nanoswarm; one did not have the necessary skills
and undertook a mass exodus ranging over 7,000 lightyears.
- 180 to 120 million years ago: The "Muuh" evolve to
primitive sophonce
- UNNAMED PLANETARY CIVILIZATION HIE565MZE (disappeared
125 million years ago)
- Overview
- Homeworld: Info to be added later
- Biology: Little information
- Impact on Earth's evolution: 0 (No known interstellar
travel)
- circa 90 million years ago: The
"Jacks" form their most recent civilization, which collapses after
82,000 years
TERRAN
CENOZOIC ERA: Tertiary
Age of mammals, birds, modern invertebrates, current
continents emerge, initial tropical conditions give rise to colder
drier climate, evolution of anthropoid apes and finally
australopithecine hominids.
- circa 50 million years ago: The "Muuh" achieve
spaceflight and interstellar travel
- circa 40 million years ago, - estimated
establishment of BGC-based
xenosophont virch world Steelcliff
- THE "Tunnlers" [INTERSTELLAR
CIVILIZATION HIE441CZE] (extinct 33 million years ago)
- Summary of discovery and exploration
- Impact on Earth's evolution: 0 (No evidence
territory extended to Sol System)
- c. 28-32 million years ago: "Soft
Ones" were
provolved by the "Muuh"
to sapience.
- UNNAMED INTERSTELLAR
CIVILIZATION
HIE121CZE (disappeared 31 million years ago)
- Overview
- Homeworld: Possibly destroyed/devastated
- Biology: Info to be added later
- Impact on Earth's evolution: Uncertain
- 20-28 million years ago: the
"Soft Ones"
slowly developed several technological cultures
- 19.6 million years ago:
species HIE636MZE apparently is exterminated by a nanoswarm
of its own creation. For over 18,000 years the nanoswarm expanded,
scouring hundreds of star systems for resources including 27 known
systems in current terragen space
- 14.8 million years ago:
The "Muuh" are
slaughtered by a fleet of automated war machines and only a few
colonies are spared. At about the same time "Black Acropolis"
civilization abruptly disappears. The HIE072CZE withdraw from known
space. Some explain these events on Dawn Hunters or
other supposed inhibitor civilizations, but there is no unconfirmed
evidence this is the case.
- 10.7 million years ago: Labyrinth
complex constructed by an unknown alien race.
- 8.3 million years ago: "Soft
Ones" again
contacted by a "Muuh"
provolve ship. The oldest indigenous Soft One recorded history dates
from this time.
- THE IAHI DAON COLONIAL EMPIRE
(extinct
7.2 million years ago)
- 5.4 million years ago: the
long-lived silicon-gen civilization HIE072CZE is almost overrun by its
own nanoswarms.
Their own Enforcers saved them but were let loose on the rest of the
galaxy as 'tracker mines' that are still a threat to unwary starships.
- 4.7 million years ago: "Soft
Ones" achieve
starfaring capability. Begin sub-relativistic colonizing nearby star
systems. Friendly contact with a number of other civilizations
- THE "Doreens" [INTERPLANETARY
CIVILIZATION HIE500CZE=HIE282RZE/D1] (extinct 4 million
years ago)
- Summary
- Note: evolved from life forms left behind
by "Halogenics" on the planet Omicron Afri III nearly 780 million years
before, but culturally completely unrelated.
- Impact on Earth's evolution: 0 (No known
interstellar travel)
- 3.6 million years ago: "Auld
Limner" species
raised to sophonce by a Soft Ones artisan clade. It is believed these
"progenitors" may have also provolved of a number of local races in the
outer Perseus or Outer Arm
- 3.15 million years ago:
Several "Soft One"
and other sophont species leave this region of the galaxy in a great
exodus
- Thyresta

- Overview (under
construction)
- Homeworld: New Montana
(YTS-4885002-3825-IV; MPA volume)

TERRAN
CENOZOIC ERA: Quaternary
Ice Age, Rise of Man (Homo erectus, Neanderthal and Cro
Magnon) and use of stone tools and fire, Pleistocene megafauna
worldwide, many interglacial warm periods, extinction of Megafauna
- 1.2 million years ago: the Ultimates
colonize several Black
Acropolis biospheres - after a short period of expansion
settle into a static society.
- 350,000 years ago: the
"Great Reformation", an attempt by the Ultimates of the
Shining Path Morph to revive the morphospecies, institutes a brief
renaissance, and a period of colonisation ("The Seeding") of nearby
worlds
- 204,000 years ago: the
last of the Ultimate Colonies ("Fruits") disappear. In the sheltered
biospheres of the Black Acropolis the descendants of the Shining Path
Morph have once long ossified into a self-cocooned equilibrium state
- 100,000 years ago: the
cocooned Ultimates
are slowly diminishing in numbers
- 50,000 - 36,000 b.c.e: The
most recent cycle of "Auld
Limner" civilization develops
- 22,000 - 18,100 b.c.e: Auld
Limner Empire -
a short-lived dominion some 2000 light years in diameter.
