| Message | Dear Dr. Musser- I enjoyed reading your recent article in Sci Am concerning a possible gravitational equivalent to the magnetic field. This should be easy to test, since a gyroscope should be analogous to an electromagnet. If gyros were mounted inside buoyant spheres, weighted so they'd float with their axes horizontal, it seems likely that even a small interaction might be detectable. If the gravitational inductance field is completely analogous to the magnetic field, my guess is that they should interact opposite to magnets - i.e. like poles should attract. |

| Message | Dear George, I’m the commissioning editor at a small publisher based in the UK (though our books are published worldwide). Apologies for emailing you out of the blue, but I’m looking for an author to help with a new concept that I’m developing called “The Rules of the Universe: Revealing the Mathematical and Physical Constants that Shape Our Cosmos”. I found your details on the NASW website (having seen your book about String Theory on Amazon) and wondered if you might be interested. The project is still at a very early stage. For the time being, I'm hoping to find someone who can (for a fee) develop a synopsis and write the text for some sample spreads. If you’d like to know more about the project, please let me know; I’d be happy to fill you in on the details and answer any questions that you might have. Kind regards, James -- James Evans Executive Editor Quid Publishing Level 4 Sheridan House 114 Western Road Hove BN3 1DD +44 (0)1273 716026 |

| Message | George, Hello, my name is James Knapp and I'm a recently published Science Fiction author...my next project involves elements of string theory and I was wondering if I couldn't trouble you to bat a few hypothetical questions around. I'm no physicist but I want to stay as rooted in fact as I can - that said the things I'm wondering about are a little 'out there' that the material I've found so far don't really cover (complete 'what if' stuff). If you'd be willing to field some very speculative questions I'd appreciate it. Thanks, James |

| Message | Dear Mr. Musser: I enjoyed reading the special edition of Scientific American on "the end", and your article in particular. I find notions of time to be a particularly intriguing topic, and I've been pleased to see this subject featured in a number of recent articles in SA. I suppose the thing that makes time so interesting is that all the greatest minds of our civilization have not yet figured out what it is. I am by no means a scientific genius, but I do at least understand the basics of String Theory. Frankly, I find String Theory to be troubling. That's not because of the mathematics (which I accept), but rather because I think the grand unifying theory ought to be more intuitively appealing. My discomfort with String Theory led me to develop another framework that I call Elastic Space Theory. Simply put, if we consider Space as being quantized (as in Loop Quantum Gravity), then we can do away with the inconvenient extra dimensions of Space found in String Theory. As the universe expands, the "pieces" of space must stretch. Thus, per my Elastic Space Theory "Time is the stretching of Space". I would be pleased to send you a short paper which expands on the concepts of Elastic Space Theory. If you wish to read it, please respond with an e-mail address where I can send an attachment. Yours truly, Brian Greaves Dundas, Ontario |

| Message | I've been working on the following program. The super-classical limit of the not mathematically well-defined QED in a curved spacetime is the mathematically well-defined Einstein-Maxwell-Dirac system. (One could get a similar system for the standard model.) As a super theory, EMD violates the positivity condition in the Penrose-Hawking Singularity Theorem. Thus, it is possible that there would be complete solutions without any singularities-Yau has in fact constructed some. Furthermore, it is known that the Einstein-Maxwell-Dirac system admits of solitonic solutions, i.e. classical electrons and photons. This is the kind of theory Einstein was hoping for. EMD is also a totally geometricized theory as a non-commutative geometry; here, the charge e and the mass m of the electron are geometric invariants of the non-commutative geometry analogous to pi! I'm trying to redo standard Big Bang Cosmology (e.g. as in Weinberg's recent text) in this context. |
