I realize that there are unsolved problems in quantum mechanics that can be 
solved by adding dimensions, whether spatial or time.  I also know that 
added dimensions are describable mathematically, and that some (Tegmark) 
hold that this makes them real.  However, as Jonathan points out with 
respect to Geddes's speculation, extra dimensions are not yet testable. 
Until they are, we can just as well invoke fairy dust - or God - or 
whatever - to explain the QM problems.

I've read this and the author's prior two papers on multi-dimensional time.

It appears that his mathematical formulation is able describe a variety of 
quantum-mechanical properties by adding one or more additional time 
dimensions to the classical derivations of motion, momentum, energy, etc. As 
a result he ends up with a 3-space, 3-time dimension theory that is simple 
and elegant. (The additional two time dimensions are closed loops on the 
scale of the Plank length.)

I'm not nearly knowledgeable enough on the subject to pick out any logical 
errors.  However, the papers are somewhat disorganized so it's hard to see 
what assumptions are being made or what contradictions with established 
theories or experiment there might be.  This also may be a language issue as 
it's clear English is not the author's native tongue.

But--the papers do not make any testable predictions that I can see, which 
is a big red flag.

In addition, the author is a "wave function collapse" kind of guy. I'm 
curious how his derivation would hold up from the MWI perspective.
