I noticed one error sentence in my old summary of my Usenet articles
(Readme.all): the following lines are false (due my confusion mixed from Indian Wisdom texts and the Holy Bible texts): **************************START of error lines***************** "There also exist structure called God's houses, which is certain number of mini-universes arranged on straight line like pearls on ribbon." **************************END error lines********************** Summary files (three together) are stored in: ftp://ftp.funet.fi/.m/pub/doc/misc/H...das/Readme.all (collected 19.10.1994) (stored 26.10.1994) other two summary text files (ASCII) are Readme.MID a(stored 6.11.1996) and Readme.SEE (stored 3.11.1996). I'am sorry about the error. Best Regards, Hannu Poropudas |

Complaint about Alan M. Schwartz unbusinesslike
posting in News groups sci.astro, sci.physics and sci.physics.particle. Alan M. Schwartz ( = Uncle Al) his real name and his present email address mentioned in his article "Affine versus metric gravitation parity test" 22 Nov 2004 (04.80.Cc, 11.30.Er). His real name Uncle Alan M. Schwartz is mentioned also in article " Galileo; inertia, and free fall", 21 Nov 2001 11:42:21 -0800, Message_ID = written by (Auntie_Al) in Newsgroup alt.sci.physics) I ask that how a person who call himself a scientist writes such a **** about which is a copy below ?

Critics about Uncle Al's writing
(Schwartz Alan M. 2004. Affine versus metric gravitation parity. 12 pages. 31.1.2005 online Uncle Al's homepage. 12 Nov 2004, 04.80.Cc, 11.30.Er http://www.mazepath.com/uncleal/qz.pdf ): "A teleparallel gravitation stress-energy pseudotensor antisymmetric to parity transformation constructs volume integral for total gravitation four-momentum and total angular momentum. It obtains by comparing vectors at different points of spacetime- a coframe field - unlike GR. When the coframe field changes the pseudotensor changes (not gauge - invariant; not covariant under general coordinate transformations) [8]. This defines an integral energy-momentum as a redistribution of energy between material and gravitation (coframe) fields obeying an exact conservation law. The Lagrangian for GR can arise from the coframe field only and be antisymmetric to parity transformation. Extremal parity test masses may violate the EP." (Schwartz) EP = Equivalence Principle "The Weak EP assumes a flat gravitation field is a local approximation around a given world-point. Stronger EP statements include the Weak EP [1]." (Schwartz) "Affine / teleparallel theories embody spacetime torsion. They ignore the EP and can violate it [3]." (Schwartz) Above text are from (Uncle Al = Alan M. Schwartz) Schwartz Alan M. 2004. Affine versus metric gravitation parity. 12 pages. 31.1.2005 online Uncle Al's homepage. 12 Nov 2004, 04.80.Cc, 11.30.Er Critics: The weak point of the writing (and hence the whole writing may be questionable) may be the following: "It obtains by comparing vectors at different points of spacetime- a coframe field - unlike GR." I think that "comparing vectors at different points of spacetime" is a mathematical problem which is not solved in GR . Parallel transport is one tool in trying to solve this in GR but it depends on the path in question. The problem in trying to generalize equation covariat_div(T) + sum_mu nabla_mu(T) = 0 ,where T is called the stress-energy tensor into integral form is best explained by Michael Weiss and John Baez ("Is Energy Conserved in General Relativity" in Physics FAQ dated 7.11.2000): We would need an extension of Gauss's theorem. Now the flux through a face is not a scalar, but a vector (the flux of energy-momentum through the face). The argument just sketched involves adding these vectors, which are defined at different points in spacetime. Such "remote vector comparison" runs into trouble precisely for curved spacetimes. The mathematician Levi-Civita invented the standard solution to this problem, and dubbed it "parallel transport". It is easy to picture parallel transport: just move the vector along a path, keeping its direction "as constant as possible". The parallel transport of a vector depends on the transportation path. But parallel transportation over an "infinitesimal distance" suffers no such ambiguity. (It's not hard to see the connection with curvature). To compute a divergence, we need to compare quantities (here vectors) on opposite faces. Using parallel transport for this leads to the covariant divergence. This is well-defined, because we are dealing with an infinitesimal hypervolume. But to add up fluxes all over a finite-sized hypervolume (as in the contemplated extension of Gauss's theorem) runs smack into dependence on transportation path. So the flux integral is not well-defined, and we have no analogue for Gauss's theorem (Weiss, Baez). Pseudotensors may indicate that total energy is not properly defined at least in GR. I investigated also related problem when I defined +, -, * and / operations for my directed geodesic lines on a sphere surface (special case) in my surface algebras but I think that question remained somehow open to further investigations (definitions succeeded when directed geodesic lines started from the same point but how to define +, -, * and / operations for directed geodesic lines which starts from different points remained somehow open except the case of - operation in first case where one directed geodesic line was moved to start from the same starting point as others). Steve Carlip wrote: Local conservation of energy holds only in a stationary gravitational field in GR. In particular, an an expanding Universe is not stationary, and there is no local energy conservation law. Also in GR, no local gravitational potential energy density can be defined. The principle of equivalence implies that there can be no covariant gravitational stress-energy tensor due one can always choose coordinates in which the geodesics are arbitrarily close to straight line in a small region, which implies that the gravitational energy in that region is arbitrarily close to zero; but a tensor that vanishes in any coordinate system vanishes in every coordinate system. The best one can hope for is a "quasilocal gravitational energy", energy defined in a finite region. (Steve Carlip: " energy in a comoving volume, where is the energy going ?", sci.astro.research, 10.12.2001 and "Gravitational Potential in GR", sci.physics.relativity, 23.2.1998). If I remember right H-M said years ago that the Weak Equivalence Principle (local property) is correct but the Strong Equivalence Principle (global property) is wrong.
