What would you want me to say? Yes or no you'd not know or not. How could I teach a cat to talk to a toaster. Yes would end up in other minds no and no would end up yes. So how would I answer.?when you go back it's not like going forward. Back you take the risk of not coming back at all. Having to accept you are there and not going anywhere. I can tell you yes you can send a human through the vibrations of time. Sending tech though is a problem of sorts. Hope this helps you.
Are you implying that you know how to travel backward in time?
Just answer honestly.
