Communication with The Past

One outlines a proposal for an experiment to communicate with the past. One considers using advanced waves, produced in the same way that was discovered by Darko Bajlo. The advanced waves are both incoming from the past and outgoing into the past, reflecting the speculation that there are two flows of time, one into the past and one into the future. Using techniques of radio direction finding, information can be extracted from an observer with a transmitter in the past, by the fact of the advanced waves being incoming waves, and then sending a signal in response to the retarded signal in the past, thereby having two-way communication. One also considers using tachyons if tachyons behave in the same way as advanced waves. If one had a constant supply of tachyons, one could modulate these tachyons to send a signal into the past. Lastly, one speculates if Tesla and Marconi might have received signals from the future.
