French brothers, Igor and Grichka Bogdanov, both had their PhD theses accepted by the physics department at Bourgogne university, France, and have published papers in respectable physics journals, such as *Annals of Physics* and *Classical and Quantum Gravity*.

Their theory apparently concerns the "topological state" of spacetime, at "scale zero". For example, the abstract from Igor's thesis starts off:

We propose in this research a new solution regarding the existence and the content of the initial spacetime singularity. In the context of topological field theory we consider that the initial singularity of space-time corresponds to a zero size singular gravitational instanton characterized by a Riemannian metric configuration (++++) in dimension D = 4. Connected with some unexpected topological data corresponding to the zero scale of space-time, the initial singularity is thus not considered in terms of divergences of physical fields but can be resolved in the frame of topological field theory. We get this result from the physical observation that the pre-spacetime is in a thermal equilibrium at the Planck scale.

and concludes:

... we conjecture that the problem of inertial interaction might be explained in terms of topological amplitude connected with the singular zero size gravitational instanton corresponding to the initial singularity of spacetime.

Commenting in the usenet newsgroup sci.physics.research, physics professor John Baez (one of the world's leading mathematical physicists) says he "can [...] assure you that the abstracts seem like gibberish to me, even though I know what most of the buzzwords mean. The journal articles make for rather strange reading [...] Some parts almost seem to make sense, but the more carefully you read them, the less sense they make."

Baez goes on to extract the start of Igor's paper *"Topological theory of intertia*" (*Czechoslovak Journal of Physics*, 51 (2001), 1153-1236.) to illustrate his point:

The phenomenon of inertia - or "pseudo-force" according to E. Mach [1] - has recently been presented by J. P. Vigier as one of the "unsolved mysteries of modern physics". Indeed our point of view is that this important question, which is well formulated in the context of Mach's principle, cannot be resolved or even understood in the framework of conventional field theory.Here we suggest a novel approach, a direct outcome of the topological field theory proposed by Edward Witten in 1988 [3]. According to this approach, beyond the interpretation propoosed by Mach, we consider inertia as a

topological field, linked to the topological chargeQ= 1 of the "singular zero size gravitational instanton" [4] which, according to [5], can be identified with the initial singularity of space-time in the standard model.

and the conclusion, that

whatever the orientation, the plane of oscillation of Foucault's pendulum is necessarily aligned with the initial singularity marking the origin of physical space S^{3}, that of Euclidean space E^{4}(described by the family of instants I_{β}of whatever radius β), and, finally, that of Lorentzian space-time M^{4}.

According to rumours reported by Baez, the Bogdanovs are "journalists and science fiction writers, both in their late 40's". After gaining fluency in some of the jargon of modern physics by interviewing French string theorists, they "spread rumors that they were geniuses and their theses were a milestone in theoretical physics".

Having made almost a state event of their thesis defences (inviting the national media, wining and dining the president of France, renting a large venue for the occasion) they were both rewarded with passes. Their theses can (at the moment) be found on the "Theses Online" site, at the urls given below.
