Further Visions

It is good when a future history series has an episode set in a further future, giving us a hint of  "what happened later" or "how it all turned out." Counting The Time Machine as a miniature future history, we can take our examples from:

HG Wells;
Robert Heinlein;
James Blish (2);
Poul Anderson (2);
Larry Niven.

After spending a few days with the Morlocks and Eloi, the Time Traveler has his "Further Vision" of the end of life on Earth.

Volume V of Heinlein's Future History shows us what became of the original generation ship.

In Volume IV of Blish's Cities In Flight:

the Web of Hercules has replaced Earthman culture in the Milky Way;
Earthmen have settled the Greater Magellanic Cloud;
the planet He returns from intergalactic space;
before a cosmic collision, Herculeans and human beings contend to occupy the Metagalactic Center;
after the collision, Hevians and New Earthmen create new universes from their own bodies while the Herculeans leave a record that will be read in a subsequent universe.

In Book Four of Blish's The Seedling Stars, Adapted Men have spread through the galaxy and will recolonize a changed Earth.

In Anderson's "The Chapter Ends," human civilization has moved to the Galactic Center, leaving the periphery to gas giant dwellers.

In Anderson's "Starfog":

human civilizations have spread through several spiral arms;
the no longer human descendants of earlier exiles are encountered;
mining the Cloud Universe will generate immense wealth.

In Niven's "Safe At Any Speed":

Known Space has become the Thousand Worlds;
technology is at its peak;
a gene for luck has become dominant.

We celebrate creative imagination!
