Einstein and Popper have established a doctrine that has proved
victorious: you can legitimately obtain any result through thought experiments but no such result can refute the theory since, for refutation, only REAL experiments matter. In fact, the doctrine is more than victorious since, especially for inertial frames, relevant REAL experiments are difficult even to imagine. So you are allowed to obtain time dilation in a thought experiment and the result will even enter textbooks but if in another thought experiment this time dilation is shown to be contradictory, there will be no consequences: the first positive result will remain unchallenged in textbooks. In fact, ALL the corollaries of the principle of constancy of the speed of light can be shown to be contradictory for the simple reason that the principle is false (that is, there is an original contradiction between the false "c" principle and the true "c+v" principle).

In fact, the doctrine is more than victorious since, especially for inertial frames, relevant REAL experiments are difficult even to imagine. Since the Principle of Inertia is just as idealized as any thought experiment, it too is under your broad-stroked attack. The inertia principle can never be tested in a gravity-free region of space because, as far as we know, there is no such thing. Imagining a free particle to travel in a straight line forever is a thought experiment in itself! Physics is a lot about imagining where no thoughts have gone before. |

See an example in http://www.wbabin.net/valev/valev7.htm . Pentcho Valev Thought experiments are designed to test the internal logical consistency of a theory. This does not in any way guarantee that the theory has any bearing on reality. It is essential that a theory also produce (unique) predictions of what will be observed in an experiment. Success in this venture is what increases likelihood that the theory has something to do with reality. You are under the misapprehension that relativity predicts contradictory things in thought experiments. It does not, and your perception is perhaps due to a limited or faulty understanding of the thought experiments. You apparently are also ignoring the experimental tests that have been brought to bear against relativity. PD |

Explanation: http://www.ebicom.net/~rsf1/sekerin.htm (fig 3) So, this guy seems to think the current explanation of variable stars is lacking and provides a different one. I'm unclear why the current explanation is lacking, why his is better, and what this has to do with relativity in the first place. The link to Velikovsky on the front page does not give me confidence that he isn't a fruitloop. (Or stars explode twice in three months). Variable. Stars. Not. Nova. Alan -- Defendit numerus |

In fact, the doctrine is more than victorious since, especially for inertial frames, relevant REAL experiments are difficult even to imagine. Do you know of a single -real- experiment that falsifies relativity. If so, please give us a reference in the refereed literature. Relativity predicts the motion of the stars. In the outer edge of the galaxy, its predictions are wrong. General relativity has been falsified by those observations. There are multiple efforts to patch it back together so those predictions work. But GR as it exists today has been falsified. The main virtue of relativity theory is that it leads to empirically correct predictions. If you ignore the predictions where it fails, sure. That is the one and only Gold Standard of a science. How well does it predict. That is all that matters. And the lesson here is: relativity does not make correct predictions all the time. |

Do you know of a single -real- experiment that falsifies relativity. If so, please give us a reference in the refereed literature. Relativity predicts the motion of the stars. In the outer edge of the galaxy, its predictions are wrong. You're already wrong, and it doesn't matter in the least whether you're talking about relativity or classical physics in the above. Predictions from a theory are based on: 1) The theory itself. 2) Input data. For example, even using Newtonian mechanics, in order to predict the motion of a given planet in the Solar system, you need (in addition to newton's laws of motion and Newton's law of gravity) good input data ragarding locations and masses of all the other planets (not to mention the Sun, of course). Failing this, you get wrong predictions, and this has nothing to do with the correctness (or lack of) of the theory. Since the data regarding mass distributions in galaxies is rather sketchy, there is no sufficient information to decide whether this illustrates a problem with the theory or not. General relativity has been falsified by those observations. You can repeat this till you're blue in the face and the statement is still incorrect.
