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.
