This brings as much ethical concerns as artificial intelligence

So.. Yes I am late but by now we all know that time isn't a linear concept anyway so it makes no difference. Although if you give this excuse to your boss he might not be too pleased!

Time...I have be wondering about it since watching ‘While we were young’ but it was recently reinforced in therapy when I was asked by a patient to regress him to the past since there was something he had done that wasn’t happy about it and wanted to undo it. Staring into his eyes for a second it occurred to me that this might not be safe territory to go. Where’s the exit? Had he killed anyone? I proceeded with care asking indirect questions to find out exactly what he was determined to rewind.  I am used to ‘regress’ patients with the intention of healing traumatic events or to reveal the cause of a particular symptom but never to actually change the conduit of life events.

According to my beliefs we can’t undo an action, all we can do is to minimize the consequences by talking to the person that we have harmed but if he/she doesn't want to be contacted we just have to accept and respect.  Hopefully we will learn with the mistake and know better next time.

Can we change the course of history by the use of astral travelling or any other projection techniques?

If there’s such a thing called destiny, can we turn away from it altogether and create a completely new canvases by manipulating the past? This brings as much ethical concerns as artificial intelligence. There are certain things that scare me and one thing is for sure, fate seems to have a very tricky way to show up unexpectedly. Ask Oedipus!
