The concept of this setting was to consider that most
science fiction stories dealing with multiverses almost always show off
realities where the changes to history are extremely recent (within a couple
centuries at most), and are almost always in regards to differences in human
civilization as a result of human actions. That’s interesting and all, but I
wondered about a story where, instead of finding other human-inhabited Earths,
it turns out the changes across the multiverse were a lot more drastic.
OUR EARTH, circa 2145
A.D.
Dimensional-crossing experimentation is discovered, and believed to be a much more “practical” means of expanding humanity off-planet, since Faster Than Light technology never developed. Tenuous explorations using probes sent to several alternate universes confirm that habitable versions of Earth do exist, but the typical view of Multiverse Theory involving Infinite Timelines doesn’t seem to hold up. In no other version of Earth thus far found is there any form of humanity, save a couple of worlds where they no longer exist. In fact, most versions of Earth are not even hospitable to Earthly life.
If the more traditional idea of alternate timelines are at
play, where all known worlds branched off from a prime world at some point in an
otherwise similar history, then the divergences across the multiverse seem to
have occurred in wildly different eras, which change Earth into what may as
well be entirely different planets in these alternate worlds.
The Earths found initially are colloquially called:
