I would rather not say, i read all about it and I can tell you as a practitioner of the occult I know that there are many technological devices that can produce astral travel. This man is claiming physical time travel after getting used to the frequencies etc and I have to be honest real life time travel done by governments in the past hundred years has been haphazard and dangerous with catastrophic results. It involves huge amounts of electricity.
John Hutchinson has been doing amazing things with experiments but time travel is not one of them that I know of. Although the scientific community does not take him seriously the united states government indeed does watch him closely. The first person to openly admit to time travel that actually works will be interrogated executed immediately and his equipment confiscated. I had a friend who was a Colonel and I guess somewhere in some documents that are dedicated to dealing with things we don't know about it's how they are intended to handle it. This is how we know they have already perfected it. Otherwise the orders would be to only confiscate it because they would need the scientist to teach them how to build it. But since the orders are to interrogate "torture for info" then execute the prisoner.
Just a comment regarding Crowley and his works. which have read and reread some of his books I have in my study since retired. Makes interesting but I wonder about what he "said" he could, believed it, or didn't do all he claimed. Still aaan interesting man regardless of what one might of him personally.
