In
the Contact Series, I touch on the concept of sending information back
in time. There has been a lot of discussion about time travel among many
of today’s physicists. A topic that would never have been taken
seriously by scientists previously has finally received a serious
examination. Unfortunately most agree that nature conspires against the
possibility of making a trip back in time. The amount of energy required
either becomes impractical or impossible, depending on who you listen
to (and I really wanted a time machine, too).
But
what about sending information back through time? I read about Ronald
Mallett’s work using lasers to distort spacetime and create a method for
time travel. While his work is very controversial it does have some
valid points and is based in science. Harold White and the Icarus
project have also proposed using light to warp spacetime, so the jury is
still out considering whether time travel will ever be possible.
I
personally don’t believe we will ever have a time machine capable of
transporting a person back in time. It simply creates too many physical
paradoxes. But I find the possibility of sending information into the
past fascinating.
Suppose
a devise is invented that can transmit data into the past. It might
only be able to send the information to itself, but even that would have
far reaching ramifications. How would it work? In the novel I described
the devise as a time-well. Information could be dropped into the well
on a specific date, for instance January first, 2099, and appear in the
same time-well fifty years earlier, January first 2049. This information
could then be used accordingly (instant lotto winner, guaranteed stock
picks, avoidance of natural disasters).
In
the book it is used to solve the problem of communications over great
distances. The problem of sending a message to a star ship 20 light
years away is that the message is twenty years old when it gets to the
star ship. By utilizing a time-well, the message could be sent twenty
years into the past and then sent out to where the star ship would be in
twenty years. The message would appear to be instantaneous. The reply
could be handled in the same manner aboard the star ship if they also
had a time-well.
Of
course this “opens a whole ‘nother can of worms,” as my grandfather
used to say. Why not just read all the messages from the future before
you leave. Then you can avoid any nasty surprises or unfortunate space
battles that you might lose. How would knowing the future, change the
future? And what paradoxes would result from having the information?
Would your time-well fill to overflowing with messages from alternative
futures, all possible futures?
It
could also lead to some very creative story writing, the challenge is
making the story simple versus so convoluted and confusing that the
reader is hopelessly lost. It is just one of the many ideas that I
touched upon in the Contact Series, hoping to give the reader something
to consider.
