TIME LINE of Larry Niven's Known Space Universe

Compiled by I. Marc Carlson( marc-carlson@utulsa.edu ) Some additional material by Richard S. Holmes, and by "sloan@geosim.msfc.nasa.gov".

If you like the occasional hypothesis that I have left strewn about within, please recall where you found it.

Notes on sources:

The sources used for this were Larry Niven's stories and novels. Some details from the Ringworld Game by Chaosium were added as well, and are noted as such.

The codes in parentheses indicate the source.

• KSC = The Known Space Chronology,
  published in Tales of Known Space (1975).
• Game = Ringworld Role Playing Game by Chaosium.
• MKW # = The series of short stories under the series title The Man-Kzin Wars,
  followed by the volume that the story occurs in.

The above materials will be superseded should different information be published.

Finally, all items marked with an * are conjecture, based on the information on hand, and may be further explained by a description in brackets.

It should be noted that the dates of the Gil Hamilton stories are absolutely internally inconsistent

c 15 Billion Years Ago

Creation of the Universe. [Ya gotta start somewhere!]

c 10 Billion Years Ago

Galaxies form.

9 Billion Years Ago

The "Outsiders" watch as planet-based sapients begin to develop.
(MKW7 "A Darker Geometry")

1.5 Billion Years Ago

The Thrint, later known as the "Slavers", rule the Galaxy.
[This is described as anywhere from 1.5 to 3 Billion years ago].

The crypto-Ptavv Guerdoth's Pruntaquilan Balladeer Coquaturia is hidden in a stasis box.
(MKW5 "Hey Diddle Diddle")

In the last decades before the end of their rule, a thrint named Plorn's tnuctip slaves produce antigravity, ruining the need for Stage Trees to launch material, and precipitating a major economic crash.
("World of Ptavvs", "A Relic of Empire")

At this point, Kzanol experiences a failure of his ship, which he abandons. He aims it at the eighth world of F124, and places himself in stasis. His ship slams into a moon orbiting the eighth world, tearing the moon from its orbit and forming the planet later called Pluto. Kzanol slams into the algae-covered sea of F124 - III, later known as Earth.
("World of Ptavvs")

Before Kzanol actually impacts onto Earth, the Thrint Empire is engulfed in a civil war that will last for a century. This long revolt is led by the Tnuctipun, using their weapons of Sunflowers, and their Bandersnatchi / Whitefood spies. This war quickly involves all known species in the Galaxy, presumably excepting the Outsiders.
("World of Ptavvs", "The Soft Weapon")

As it becomes clear that the war is lost, the surviving Thrint build a giant telepathic Amplifier designed to order all sentients in the Galaxy to commit suicide on "Last Day".
("World of Ptavvs", MKW3 "The Asteroid Queen")

Durvash the Tnuctipun spy discovers a way to halt the impending Suicide Time, but his ship is thrust into Stasis by the impact of a Thrinti Godfist weapon that imbeds the tnuctip vessel into the molten crust of what will someday become the Jotun Mountains of Wunderland.
(MKW5 "The Hall of the Mountain King")

A day or so before the Last Day/Suicide Time, Dnivtopun, Overseer of a food world in the 7-1Z-A (Alpha Centauri) System, his wives and his young son, suffer an accident that seals them in a stasis field.
(MKW3 "The Asteroid Queen")
