PRLog - Dec. 26, 2012 - "I solemnly swear, if at any point in life I have the ability to travel in Time and Space, I will visit myself December 21, 2012". That was the oath that thousands had taken as part of the, "I Am Time Loop" project ( http://vimeo.com/

"I like the I Am Time Loop movement, it' s just that's its predicated on a popular misunderstanding of the geometries of time travel, so it's doomed to fail", Marshall remarked. "I could have announced that it would, in advance, but I didn't want to rain on their parade, but its really quite obvious why it wouldn't work".
Marshall explains that the I Am Time Loop concept suffers from too many hidden assumptions, a concept that he is expert on and lectured about at the 2004 Mars Society Conference in Chicago. He laid out the problems by the numbers:
1. The assumption that time travel will be available to the same participants in the future who are promising to time travel now.
2. The assumption that anyone of them will be alive in the future.
3. The assumption that time actually can become a linear closed time-like loop.
4. The assumption that all time is now.
"1 and 2 are pretty straight forward as depending on opportunity,"
Marshall explains that the loop is actually a coil, not a circle, and like many things physicists do, the loop is really just a 2 dimensional rendering of the proper geometry but that everyone has forgotten that, just that many physicists forget that 2 dimensional embedded diagrams of wormholes are not the way that wormholes actually look or work.
"Another way to look at it is that between the time the promise is made, and the event takes place, something could happen that would prevent the event. However, in the future they could travel back in time and arrive in a parallel universe where the event did take place and keep their promise. There's nothing ruling that out because it doesn't violate anything from quantum mechanics. However, the first version - their version does, because all travel backward in time must involve parallel universes, so the action that you initiate on one timeline - in this case the promise to travel back to a date, which at the time of the promise has not yet occurred, would be fulfilled in a parallel timeline. It's not so much that that action violates Copenhagen, for example, but the geometry that it uses would, and that geometry doesn't exist, as I am proving in my special report to Congress".
Marshall's report to select members of Congress will outline the fact that one of the key issues of time travel that have been misunderstood is that of geometry and that the geometry of time travel is more important than any action. Paradoxes are prevented by the geometries of time travel, not because of any action that takes place within them. Thus schemes, either for or against, paradoxes, are irrelevant because it's the geometries of time travel that determine if an action backward in time is possible or not.
"So, even though there's a new I Am Time Loop event set for 2013, the outcome may well be the same - no time travelers. However, one of these parallel universes that splits off from ours could send someone back to our timeline but the likelihood is nil. There's a near infinite number of them and there's still the sequential nature of time to deal with. It's all very complicated, but I am working it in a new formula that describes how the quantum mechanics and relativity would work together into a cogent description of that reality."
Marshall is encouraged by the enthusiasm of the I Am Time Loop project and its fans, even if they're a little misguided.
"This is a neat idea in general but neat ideas don't necessarily transfer into reality. I've seen others where people have tried to start a movement to make a time machine, but that only went so far. The subject of time travel is misunderstood enough, so while it's great to get the interest up, more solid information would probably be helpful. I mean, it doesn't really matter how many followers they get that promise to travel back in time, because none of them are working on time travel and the whole idea reflects that they don't quite understand it. Ironically, they say leadership is overrated but it's people like me, who are determined, focused and don't care about movements, that make breakthroughs. My hero, when I was a teen, was Todd Rundgren who said things like, 'I'd rather live by a dream than live by a lie, Don't you follow me now. Suffer them slings and arrows, be a real man, The world doesn't own me'. If I cared about what other people thought, if I gave a damn about what was socially acceptable according to some crowd, none of the things that I've accomplished would exist (bio http://informalscience.org/
