Mi estimado Edu, si bien recuerdo, en la antiguedad, los libros
de ciencia solo se escribian en latin y creo que uno de los
problemas que tuvo nuestro gran Galileo, fue escribir sus obras
cientificas en italiano. No hace mucho vi un documental historico
donde se dijo, que dos o tres personas habian sido asesinadas
porque tradujeron la Biblia al ingles. Increible pero cierto
pero en la villa del señor hay de todo, alguna vez recuerdo que
un doctor y profesor de astronomia, no queria debatir conmigo
porque el simple hecho que yo utilizaba un alias. Que gran
suerte tenemos de tener a un Simplicio en este foro, que como
el doctor Tom van Flandern, no tiene problemas, ni prejucios
de discutir sus ideas y defender sus posiciones en los foros.
He estado unos dias apartados, por varias razones y porque
esperaba una respuesta del invitado, alguien que por cierto
siempre he admirado mucho, sobre todo por su valentia ante
tanta opresion y supresion de la ideologia cientifica imperante.
Tambien he estado trabajando en mi modelo, para ver si ya lo
puedo presentar y si no es mucho perdir quisiera que usted
simplicio, Escipion o cual de los invitados tenga la paciencia
de leerlo y de criticarlo cuando lo llegue a exponer en otro
hilo de estos foros. No hay que ser un cosmologo de profesion
para teorizar sobre el universo, aunque por supuesto conocer
de astronomia, cosmologia y metodologia cientifica ayudaria
muchisimo.
Tambien he estado estudiando sobre los ultimos comentarios de
Simplicio, sobre los supuestos errores de Van Flandern de inter-
pretar la TGR como un campo y no como una geometria del espacio
tiempo, tema que por seguro respondere muy pronto.

Saludos a todos al igual que lolo toro soy un seguidor de este hilo y no me habia animado a participar debido a no tener el nivel de conocimientos que aqui se plantea pero tengo una duda y me gustaria que me la clarificaran,como saben una de las pruebas de la TGR es la medicion de la desviacion de la luz de una estrella durante el eclipse total de sol de 1919 me gustaria saber si se ha descartado como posible causa de este fenomeno a la refraccion de la luz de la estrella debido a su paso a traves de la atmosfera solar por otra parte en lo personal no me gusta la TGR debido a que no entiendo como una teoria que pretende explicar el funcionamiento de nuestro universo no se pueda aplicar para explicar su origen(Big Bang) y hayan tenido que recurrir a la cosmologia cuantica tambien es criticable segun mi opinion lo que se esta haciendo con los resultados preliminares de la sonda probe B, en donde da la impresion de que estan ajustando los resultados a la fuerza para que concuerden con la TGR y no se considero al principio del experimento todos los factores que podian influenciar el resultado final para concluir los felicito por este hilo debido a todos los aportes que han hecho en especial para los aficionados a la astronomia y que continue ahora mas que nunca ya que se aproxima la inauguracion del LHC y se van a clarificar muchas dudas sobre el origen del universo y habra mucho tema por debatir.
En mi opinión el análisis hecho con los resultados de estos experimentos es una muestra ejemplar de manipulación de datos para lograr conclusiones inexistentes, más allá del posteriormente reconocido falseamiento de datos del astrónomo Real de Inglaterra (Dyson) y de "Sir Arthur Eddington".
Pero una cosa es que el debate deban realizarlo los cientÃficos, que deben, y otra que los legos en la materia nos abstengamos de intervenir.
A veces, solo a veces, tengo la sensación de que la cosmologÃa se parece cada vez más a un club privado en el que todos sus miembros deben pasar un rito de iniciación para que su opinión sea tenida en cuenta, y en su currÃculo deben figurar las muescas dejadas por años de estudios, trabajo de campo como investigador, publicaciones en revistas "oficiales", etc. Como en todo gremio que se precie de serlo, pero dejando poco o nulo resquicio para los aficionados.
Sin embargo, sentido común lo tenemos todos (o casi, algunos nos dimos por perdidos), y podemos formarnos una idea conceptual del problema, distinguir cuando algunos cientÃficos parecen haberse fumado algo, e incluso plantear cuestiones interesantes, que si bien triviales pueden aportar un punto de vista alternativo difÃcilmente visible dentro del bosque.
Hay que escuchar a todos, aún a los más ignorantes, pues nunca sabes de donde puede venir una gran idea.
Para terminar, os incluyo un enlace que, aunque ya lo hemos visto en este hilo, conviene releer de vez en cuando.

Hola a todos,
Les tengo una sorpresa, traduje los comentarios de Simplicio
y se los envie a Van Flandern y este en menos de dos dias ha
podido responder, asi que aqui le incluyo su respuesta.
saludos
Cuantin.
Thanks for your message. First, let me remark that my time is very limited, and I will be on travel for a week starting Thursday. So if there is follow-up to this message, your readers will need to be patient.
May I also point out that our web site, http://metaresearch.org, has computer translations available, which can be turned on for most pages. Although these are not very good translations, they might assist some of the non-English-speaking participants in your discussion.
Your correspondent’s name “Simplicio†is of course quite ironic. In my original version of “The speed of gravity – what the experiments sayâ€, I quoted this exchange:
Sagredo: But of what kind and how great must we consider this speed of light to be? Is it instantaneous or momentary or does it, like other motion, require time? Can we not decide this by experiment?
Simplicio: Everyday experience shows that the propagation of light is instantaneous; for when we see a piece of artillery fired, at great distance, the flash reaches our eyes without lapse of time; but the sound reaches the ear only after a noticeable interval.
Galileo’s Two New Sciences
If your Simplicio were faithful to the experimental facts, he might just as easily have said today: “Everyday experience shows that the propagation of gravity is instantaneous; for when we see a source mass at great distance, the gravity reaches us without lapse of time; but the photons reach the eye only after a noticeable interval.â€
His commentary is far too long and shows a failure to read many of the relevant published articles on this subject, or even the web versions available on our site. Also, much of his English is difficult to follow, though I sympathize (being someone who speaks no Spanish), and have tried my best to follow it. I will precede his comments with the notation [S] for Simplicio.
> [S]: In the classic theory of fields Newton's law of universal gravitation and Coulomb's law for charges are not valid when existing relative motion. Both are rigorously only for bodies at rest. The theoretical reason for their invalidity is that these laws describe actions at distance with infinite speed in clear contradiction with the special theory of relativity and the modern concept that interactions are executed through actual physical fields.
This introductory remark takes us right to the core of the matter. “Action at a distance†is a logical impossibility, but is a phrase we can use as an approximation of reality when interaction speeds are much faster than light. With that qualification, then I agree: near-instantaneous forces are a clear contradiction of special relativity (SR). However, that is of no importance because SR is now a falsified theory, replaced by Lorentzian relativity (LR). This was published in: “Experimental Repeal of the Speed Limit for Gravitational, Electrodynamic, and Quantum Field Interactionsâ€, T. Van Flandern and J.P. Vigier, Found.Phys. 32:1031-1068 (2002). A preprint under title “The speed of gravity – Repeal of the speed limit†is available at http://metaresearch.org/cosmology/gravity/speed_limit.asp.
If we do not agree that SR is a theory able to be falsified, and that the discovery of something propagating much faster than light in forward time would in fact falsify it, then we will certainly not agree on much else. One can read more about LR and why it has replaced SR at http://metaresearch.org/cosmology/gravity/LR.asp. Note especially that the math of the relativity of motion is unchanged, but the physics underlying that math is strikingly different.
> [S]: Newton for Law for low speeds (v <<c) gives results that fit very well with the experimental measurements,
Indeed it does, but *only* if one uses infinite force propagation speed. Any effort to reduce the interaction speed to the speed of light (c) leads to a grossly wrong theory with orbits that spiral outward. The same remark applies to electrodynamics. That is why geometric GR has needed to deny that gravity is a force, because if it is a force, the propagation speed cannot possibly be as slow as c.
> [S]: Newton's law is obtained in General Relativity as an approximation through the solution of Schwarzschild.
Clearly, S has never derived this approximation. The derivation can be seen in Einstein, A., Infeld, L., and Hoffmann, B. (1938). "The gravitational equations and the problem of motion." Ann.Math. 39, 65-100; or in Robertson, H.P. and Noonan, T.W. (1938). Relativity and Cosmology. W.B. Saunders Co., Philadelphia, 45. What is significant to note is that, whereas the Schwarzschild solution describes the field very well and has interaction speeds limited to c, the conversion to equations of motion uses *instantaneous* gradients of the field, not retarded gradients. These instantaneous gradients are the ones that would exist if the target bodies were at rest in the field. But when target bodies move, they see and sense only retarded gradients; yet the derivation uses instantaneous ones for no better reason than they must do so to get the “right†equations of motion.
This purely mathematical choice is an implicit recognition that propagation delays cannot be used in connection with gravitational forces if one wishes to describe reality.
> [S]: the experimental verification of relativistic effects in nuclear power plants and cosmic radiation confirm for neutral particles the validity of Special Theory and the Four Universal Principles and thus, indirectly, the inconsistency of interactions with infinite speed.
The same 11 independent experiments also verify LR. The only way to tell which theory is right, SR or LR, is to look for something propagating faster than light in forward time. Gravitational force has exactly that property, so LR is right and SR is wrong.
So why are particle speeds limited in accelerators? When SR was believed and taken literally, it was thought that particle masses must increase toward infinity as speeds approach c. But we now know that “rest mass†and “gravitational mass†do not change with speed, so we no longer speak of particle inertial masses approaching infinity, but rather of particle momentums approaching infinity. But there is a simpler explanation for the apparent inertia of bodies traveling near speed c. The forces attempting to push them faster are themselves limited to speed c, so the speed differential between particle and pushing force approaches zero as speed approaches c. Such forces ultimately can never push something faster than they themselves travel. However, a force not limited to speed c, such as gravity, could easily push a particle faster than speed c. (This of course is in an LR context, where nothing ever happens to “timeâ€, but only to clocks. So we mean “faster than light in forward time, not the time reversal that would be required by SR.)
The bottom line is that particle accelerator experiments have different interpretations in different models, and shed no light on the issues about gravitational force propagation speeds.
> [S]: From the standpoint of the Special Theory and the Theory of Fields, the General Theory should be considered only as a rough model. Within this framework is not worthy amending the metric space-time by matter (geometric design), which can be used as an auxiliary mathematical treatment but without physical substance
It is important to know that general relativity (GR) has always had two different physical interpretations of the same math: the “field†and the “geometric†interpretations. Feynman concluded only that the geometric interpretation was unnecessary. Vigier and I now conclude (in the paper previously cited) that the geometric interpretation is falsified because it provides no cause to initiate new motion for a target body at rest in a field, and requires creating the new 3-space momentum of the target body from nothing (a form of miracle, forbidden by deep reality physics).
Even Einstein eventually abandoned the mysticism of a purely mathematical “space-timeâ€, and began to speak in more concrete physical terms. In A. Einstein, Ether and the theory of relativity, Springer, Berlin (1920), reprinted Dover (1983), p. 23 we read: “we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense.â€
> [S]: it happens that the Special and the General Theories are incompatible and mutually exclusive.
However, unlike SR and GR, LR and GR are compatible!
> [S]: The General Theory, in its modern formulation (geometric) is trying to solve the former conditioning postulating that there are not gravity forces, giving a geometric explanation
For this statement to make any sense, one must begin by changing the definition of the word “forceâ€. The standard meaning of “force†is “the time rate of change of (3-space) momentumâ€. And because orbiting bodies are obviously changing their 3-space momentum, a force is acting by definition.
We must be careful not to mix 3-space definitions and 4-space definitions in one conversation. While math thinking favors 4-space, physical thinking (the only way to make physical sense of these equations) favors 3-space. And not coincidentally, astronomers use a Euclidean 3-space exclusively for making their measurements. So I recommend avoiding 4-space definitions and terms because they obscure the physics.
> [S]: The Lorentz transformations are deducted assuming a speed limit, which can only possess the fields, being the only possible mathematical transformations that keep the properties of space and time (inertial systems).
The “gamma†part of Lorentz transformations works well for predicting GPS clock behavior, among many other things. The “time slippage part†is apparently useless, as I explained in http://metaresearch.org/cosmology/gravity/gps-twins.asp. As electromagnetic clocks approach the speed of light, they slow, then stop, and finally break if pushed faster than c. By contrast, as gravitational clocks approach the speed of light, they remain invariant at all speeds, and provide a type of “universal time†against which the degree of simultaneity of all events can be judged in a unique, frame-independent way.
> [S]: this is inconsistent with the principle of equivalence between mass and energy
Not so. Specifically, conservation of momentum holds at all levels and in all interactions. The interpretation of “energy†is different, to no one’s surprise. Your kinetic energy right now is zero relative to the room you am in, but is large enough to vaporize you if your orbital speed around the Sun is considered. So does this super-energy exist physically inside you, or is it simply a mathematical device to describe the work you could to if you encountered some other reference frame?
> [S]: According DR Flandern we should go back to Lorentz focusing on space and time (absolute system).
The real Van Flandern, now speaking, says no such thing. LR tells us that every local gravitational potential field provides its own preferred frame, so there can be no preferred frame to the universe.
> [S]: to believe that time of a physical system itself is not depending on the acceleration. It is a common mistake of many physicists but too rude to an expert.
Claims without clear definitions are useless. If “time†is simply a human concept invented to measure change, as in deep reality physics, then it makes no sense that any material, tangible entity can interact with a concept in the human mind and change it. In LR, time is never affected, but clocks are affected, just as a temperature change affects the rate and readings of a pendulum clock but does not change “timeâ€.
> [S]: One of the arguments used by Van Flandern [sic] is that the speed of gravity is different from the electromagnetic speed. In this case the interaction between charges, which invariably hold mass, occurs for electric and gravitational fields with various delays on the same charged body.
“Electromagnetic†usually refers to light, as in “electromagnetic spectrumâ€. “Electrodynamic†is used to refer to forces between charges. Vigier and I argued that both electrodynamic and gravitational forces greatly exceed the speed of light. The Sherwin-Rawcliffe experiment showed that even when changes *accelerate*, each responds to the other’s instantaneous position, and not to some extrapolated, delayed position. This is why the hypothetical force carriers, mis-named “virtual photonsâ€, are said to travel with infinite speed -- to avoid a failure of QED theory to explain charge dynamics if these hypothetical force carriers propagated with the speed of light.
> [S]: Laplace calculation (1) is not valid in the theory of the fields. It is only a classical mechanistic solution that does not consider the gravitational field as a real physic field. In the fields theory the field has momentum and energy, and participates inexorably in the conservation of the angular movement of the system.
This reflects a poor understanding of what fields can, and cannot, do in dynamics. Actually, the field provides only the bending, redshift, and propagation delay of electromagnetic waves. Orbital dynamics could not be caused by a field unless the field’s parts propagated faster than light (which is the point of all the experiments cited in my papers). Instead, gravitational force imposes a density gradient onto the gravitational potential field near masses, just as it does to atmospheres. A “static†field around a stationary source mass cannot create its own gradient in the absence of a force, nor can it initiate new motion in a target body at rest in its field. And when two large source masses move fast (as in binary pulsars), field theory cannot explain how each always accelerates toward the other’s instantaneous position, and not toward either its retarded position or even its extrapolated, retarded position.
I repeat: the field produces only the small effects of light-bending, gravitational redshift of light, and radar propagation delay (Shapiro effect). It cannot create its own gradients, and a field gradient cannot initiate motion in a target body. But external gravitational forces can impose gradients onto fields near masses, thereby causing the small relativistic effects (especially on light) through the mechanism of refraction.
> [S]: In my opinion this conjecture by Van Flandern [sic] does not meet the minimum required to rule out universal principles: the principle of causation, the Special Theory of Relativity and the Maxwell equations.
I hold strongly to the principle of causation, and have used it to disprove SR. That is the core of our disagreement. Give me one reason why LR should not be considered superior to SR for explaining all relevant experiments, for doing so with a greater simplicity than SR, and for resolving the conflict between SR and GR? -|Tom|-
Pienso que dos dias lo tengo en castellano. Lo interesante
de todo esto, es que no solo TVF respondio a Simplicio, y
a nosotros, sino que lo puede seguir haciendo, si tenemos
paciencia ya que como la mayoria, el esta muy ocupado en
otros menesteres.
Aunque esto de la traduccion no es nada facil, por ejemplo el
escrito de Simplicio, lo traduje con un programa y se lo di a
rectificar a una amiga bastante entrenada en la traducciones para
que lo arreglara y despues lo revise y corregi un poco yo, que creia
que entendia el ingles y el español cientifico bastante "bien" y asi
todo, TVF lo encontro algo dificil de entender desde nuestro ingles.
Le confieso, que me gustaria dedicarme mas a mejorar esto de las
traducciones cientificas. Quizas en el futuro le pueda dedicar
alguna horas a la practica de la traduccion del ingles al español
y vice versa, pero si por ahora encontraramos alguien mas competente
seria mucho mejor.
Simplicio, te ha salido un duro contrincante. El tal Van Flandern se ha puesto el equipo de camuflaje nocturno para una incursión rápida en la base enemiga.

Clon maldito (Cuantin), me hubiera gustado que me consultes antes de enviar una traducción de mi post al Dr. van Flandern. Afortunadamente no lo hiciste pues creo que te hubiera dicho que no lo hagas... y luego me habrÃa arrepentido de negarme a tener esta posibilidad poco común.
No obstante, acabo de comprar un bate de baseball que pienso usar en tu cabeza.
Deseo aclarar que una discusión de este tipo probablemente va a incluir aspectos más complejos, rigurosos y abstractos, que en general he tratado de evitar, por lo cual podrÃa resultar mas difÃcil de digerir. Tengan en cuenta que se trata de dos visiones distintas de un tema central de la FÃsica.

Hola a todos,
Mi estimado Simplicio,
Como dice un viejo provervio, " Mas sabe el diablo por viejo, que
por diablo.". Esta a punto de pedirle permiso, pero como diste un
respuesta tan formal, pense que mucho le interesaria una respuesta
de TVF. Tambien no estaba del todo seguro que TVF responderia, ya
que pense que estaria muy ocupado con el proximo simposio de cosmologia
que ya esta por venir y donde el es uno de los anfritiones.
Bueno a riesgo dispare y de suerte mate a dos pajaros de un tiro y este
foro cada vez se pone mas interesante. En cuanto al bate de baseball,
esto pensando en una tecnologia del movimiento por sintonia, en movimiento
por cambios de marcos de referencias, por lo que sera muy dificil
que me alcances, ademas siempre tengo otros clonos de respuestos, que
podran suplantarme si a este lo llegas a terminal.
Muchisimas gracias por el esfuerzo, pero el problema no fue el programa
que utilice, ya que posteriormente fue revisado y arreglado por dos
personas, mas bien considero que el problema esta mas bien en la forma
de pensar de ambas culturas y la complejidad del tema. Es muy buena
idea que responda en ambos idiomas, asi nos sera mas facil seguirlo
y procesarlo.

la definición de la palabra “fuerzaâ€. El significado estándar de la “fuerza†es
“el Ãndice de tiempo de cambio del momento tridimensionalâ€. Y porque los cuerpos
orbitando, están cambiando obviamente su momento tridimensional, una fuerza está
actuando por definición.
We must be careful not to mix 3-space definitions and 4-space definitions in one
conversation. While math thinking favors 4-space, physical thinking (the only way
to make physical sense of these equations) favors 3-space. And not coincidentally,
astronomers use a Euclidean 3-space exclusively for making their measurements. So
I recommend avoiding 4-space definitions and terms because they obscure the physics.
Debemos tener cuidados de no mezclar las definiciones del espacio en tres dimensiones
y las definiciones del espacio en 4 dimensiones. Mientras que el pensamiento matematico
favorecen el espacio en cuatro dimensiones, en el sentido fisico (la única manera de tener
sentido fÃsico de estas ecuaciones) favorece a el espacio de 3 dimensiones.
astrónomos utilizan un espacio euclidiano de 3 diemsiones exclusivamente para hacer sus
medidas. Por ende recomiendo tan el evitar el de 4 dimensiones porque obscurecen la
fÃsica.

The “gamma†part of Lorentz transformations works well for predicting GPS clock behavior, among many other things. The

The real Van Flandern, now speaking, says no such thing. LR tells us that every local gravitational potential field
provides its own preferred frame, so there can be no preferred frame to the universe.
El Van verdadero Flandern, ahora hablando, no dice tal cosa. (RL) nos dice que que cada campo potencial gravitacional local
proporciona su propio marco preferencia, por lo que no hay marco preferido del universo.

a common mistake of many physicists but too rude to an expert.

Claims without clear definitions are useless. If “time†is simply a human concept invented to measure change, as in deep
reality physics, then it makes no sense that any material, tangible entity can interact with a concept in the human mind and
change it. In LR, time is never affected, but clocks are affected, just as a temperature change affects the rate and
readings of a pendulum clock but does not change “timeâ€.
Las demandas sin definiciones claras son inútiles. Si el “tiempo†es simplemente un concepto humano inventado para medir el

tratada, y mucho menos para descartar los Principios Universales, el Principio
de Causalidad, la TeorÃa de Relatividad Especial y las ecuaciones de Maxwell.

I hold strongly to the principle of causation, and have used it to disprove SR. That is the core of our
disagreement. Give me one reason why LR should not be considered superior to SR for explaining all relevant experiments, for
doing so with a greater simplicity than SR, and for resolving the conflict between SR and GR? -|Tom|-

Me atengo fuerte al principio de causalidad, y lo he utilizado para refutar RS . Ésa es la base de nuestro
desacuerdo. ¿Darme una razón por la que LR no debe ser considerada superior al RS para explicar todos los experimentos
relevantes, para hacer tan con una mayor simplicidad que RS, y para resolver el conflicto entre el RS y GR? -|Tom|-
