Could it be possible to mentally receive or send messages or thoughts through time with some form of signal? What if it were possible to communicate via recording? How might one prove their ability to communicate using a microphone at one time and a recording at a future date? Who might conduct such a test? Assuming that this works what kind of microphone you would want to use? How do professional studio microphones and inexpensive microphones differ? Would the quality of the microphone make a difference? I am interested in knowing your thoughts about sending messages back and forth past time using a recorded message. Is this possible? What messages would you send to a recording made in the past? How might someone use their brain and a recorded message to time travel? Theoretically if you could send thoughts back in time to another person who is using recording equipment then you could time travel. Possibly brain waves could somehow connect to the magnets from a speaker and send a message to the one recording the message in the past. What are some other ways a brain and a speaker could communicate if it were possible? What do you think about this method of time travel? What would you call this method?
