The Law of Everything (aka Lagrangian) in Eight Equations?

Authors: Paul J. Werbos
Comments: 3 Pages.

Previous work has argued that many of the puzzling effects in quantum theory can be explained in principle as the emergent statistical outcome of "chaotic enough" nonlinear PDE, if no additional assumptions such as classical time-forwards statistics or renormalizations are grafted on to what can be deduced from the PDE. But what kinds of PDE could be suitable? This paper provides one (unified) candidate, based on a classical linkage of general relativity with a form of electroweak theory with modified Higgs field, hopefully yielding modified "quarks" as well as electrons as solitons. Ansatz included.

Could Hyperbolic 3-Manifolds and Hyperbolic Lattices be Relevant in Zero Energy Ontology?

Authors: Matti Pitkanen
Comments: 9 Pages.

In zero energy ontology (ZEO) lattices in the 3-D hyperbolic manifold defined by H3 (t2-x2-y2-z2=a2) (and known as hyperbolic space to distinguish it from other hyperbolic manifolds emerge naturally. The interpretation of H3 as a cosmic time=constant slice of space-time of sub-critical Robertson-Walker cosmology (giving future light-cone of M^4 at the limit of vanishing mass density) is relevant now. ZEO leads to an argument stating that once the position of the "lower" tip of causal diamond (CD) is fixed and defined as origin, the position of the "upper" tip located at H3 is quantized so that it corresponds to a point of a lattice H3/G, where G is discrete subgroup of SL(2,C) (so called Kleinian group). There is evidence for the quantization of cosmic redshifts: a possible interpretation is in terms of hyperbolic lattice structures assignable to dark matter and energy. Quantum coherence in cosmological scales would be in question. This inspires several questions. How does the crystallography in H3 relate to the standard crystallography in Eucdlidian 3-space E3? Are there general results about tesselations H3? What about hyperbolic counterparts of quasicrystals? In this article standard facts are summarized and some of these questions are briefly discussed.

Do Blackholes and Blackhole Evaporation Have TGD Counterparts?

Authors: Matti Pitkanen
Comments: 9 Pages.

The blackhole information paradox is often believed to have solution in terms of holography stating in the case of blackholes that blackhole horizon can serve as a holographic screen representing the information about the surrounding space as a hologram. The situation is however far from settled. The newest challenge is so called firewall paradox proposed by Polchinsky et al. These paradoxes strengthen the overall impression that the blackhole physics indeed represent the limit at which GRT fails and the outcome is recycling of old arguments leading nowhere. Something very important is lacking. On the other hand, some authors like Susskind claim that the physics of this century more or less reduces to that for blackholes. I however see this endless tinkering with blackholes as a decline of physics. If super string had been a success as a physical theory, we would have got rid of blackholes. If TGD is to replace GRT, it must also provide new insights to blackholes, blackhole evaporation, information paradox and firewall paradox. This inspired me to look for what blackholes and blackhole evaporation could mean in TGD framework and whether TGD can avoid the paradoxes. This kind of exercises allow also to sharpen the TGD based view about space-time and quantum and build connections to the mainstream views.

Some Solutions to the Clifford Space Gravitational Field Equations

Authors: Carlos Castro
Comments: 9 Pages. Submitted to the International Journal of Theoretical Physics.

We continue with the study of Clifford-space Gravity and find some solutions to the Clifford space ($ C$-space) generalized gravitational field equations which are obtained from a variational principle based on the generalization of the Einstein-Hilbert-Cartan action. The $C$-space connection requires $torsion$ and the field equations in $C$-space are $not$ equivalent to the ordinary gravitational equations with torsion in higher $2^D$-dimensions. We find specific metric solutions in the most simple case and discuss their difference with the metrics found in ordinary gravity.

Background Independent Relations Between Gravity and Electromagnetism

Authors: Peter Cameron
Comments: 6 Pages. added a reference to a note on the black hole information paradox

As every circuit designer knows, the flow of energy is governed by impedance matching. Classical or quantum impedances, mechanical or electromagnetic, fermionic or bosonic, topological,... To understand the flow of energy it is essential to understand the relations between the associated impedances. The connection between electromagnetism and gravitation can be made explicit by examining the impedance mismatch between the electrically charged Planck particle and the electron. This mismatch is shown to be the ratio of the gravitational and electromagnetic forces between these particles

Theory of Everything by Illusion

Authors: Kimmo Rouvari
Comments: 12 Pages.

Theory of Everything is The Holy Grail of Science. Scientists all over the world have searched it for a long time, without any convincing outcome. The best effort so far has been so called M-theory, which can't be falsified. Presented theory is a new theoretical platform which functions as the true theory of everything.

Is Quantum Gravity a Linear Theory?

Authors: Andrey Simonian (RUSSIA), Pyotr Svirov (RUSSIA)
Comments: 26 Pages.

The main idea of our quantum gravity model is following: in usual quantum mechanics we can represent any state of the many-particle system as sum over products of one-particle functions, generally, a path integral. In quantum gravity we also represent each state as such superposition. In the last part we try to make numerical calculations using our quantum gravity theory. In the case of interaction with arbitrary electromagnetic and gravitational field the wave function is similar.

To Understand the Four Cosmological Interactions

Authors: U.V.S. Seshavatharam, S. Lakshminarayana
Comments: 10 Pages. Authors request the science community to kindly look into this new approach

Considering the Hubble volume, cosmic critical density, Hubble mass and Avogadro number - in this paper an attempt is made to fit and understand the mystery of cosmic, atomic and nuclear physical parameters. This is a new approach and may be given a chance in understanding the four fundamental cosmological interactions.
