The Ilahlu Barrier was first theorized shortly after the discovery of
the first alien wormhole was discovered and traversed safely.
Since the wormhole put the expansion of civilization out much farther
than ever before, a strange, but trivial, phenomenon was
discovered. In civilization, there is a constant "suspended
chatter" from Earth along broadcast wavelengths and with a strong
enough receiver, it was postulated that it may be possible to listen
back through a few hundred years of history and re-record some events
broadcast on old wavelengths and frequencies.
The theory holds, from extremist branches of the pseudo-scientific
community that it if a powerful enough receiver can somehow be moved in
front of the first wavelengths ever broadcast from earth during the
late industrial age, it would be possible to re-record and capture
missing history from the pre-nanoswarm era. This theory, or
popular legend, requires the discovery of an alien wormhole with the
right time displacement between the mouths to allow access to the
historical light-cone; a requirement which seems unlikely or even
impossible to be ever met. But the idea persists like time
travel, faster than light movement, magic and teleportation.
The Ilahlu Barrier got its name from a short lived pop culture
phenomenon where a spate of entertainments of the time focused on the
idea of passing what they called the Ilahlu Barrier and was able to
effectively record history and find all kinds of lost secrets of
Pre-Swarm civilization. These entertainments were a very powerful
fad of it's day, but very little of them survives to this day beyond
the name of this mythical boundary, the Ilahlu Barrier. It is
claimed that you will know when you have the barrier pass over you
because you will hear an ancient theme song, being one of the most
powerful of the early broadcasts, thanks to it's repetitive broadcast
during its popularity.
In truth, today, there is a small organization devoted to monitoring
wormhole growth in the Nexus and waiting with the ability and desire to
go through any newly discovered wormhole that would put a receiver in
front of the barrier and wait to see if the theory is true, and be
ready to record any information and wisdom discovered.
