Hello, I have always been interested in time travel, and now I need to send a message to the past. I do not know how soon they will create a time machine that will be able to move small objects into the past, so I decided that I should try to create a time machine myself. And here is the circuit that I would like to try, it is based on the theory of the Tipler cylinder, this device should generate a cylinder that has no one knows how high, theoretically, if we make a few circles around it, we should be in the past. I don’t know yet how my scheme is working and I want to ask you for advice, is it worth creating it or not?
