~ In the proposed version of the theory of involution of photons, there is no decay of a photon, but an expansion of the space of the Universe, as a result of which the wavelength of the photon increases, and due to the fact that the speed of light in the process of this expansion remains the same, the frequency of the photon decreases accordingly. 122173. 2 So if instead we said: @ArturodonJuan is correct.

Nature (Nature) The first postulate upon which Einstein based the theory of special relativity relates to reference frames. C 1990; 262. You can also search for this author in Oh this is wonderful! Even today this is by many not fully understood and cause for misinterpretations and misunderstanding thus non-intuitive. Photonics are obviously inert particles and therefore will fill the space of the Universe. 1 However, this paper does not contain any discussion of Lorentz's theory or the possible difference in defining simultaneity for observers in different states of motion. If such a motion were possible then the wave would be stationary relative to the observer. (10) 1 If you remember the effect of the index of refraction from The Law of Refraction, the speed of light is lower in matter. Travelling from Frankfurt airport to Mainz with lot of luggage. sound propagates in a medium. Am J Phys 1982; 52: 119-124. = Although more limited than Einsteins second postulate (which also connects the value of k to a specific physical phenomenon), it is nevertheless an additional postulate required by the theory before it can be said to yield definite information about the world. As with many fundamental statements, there is more to this postulate than meets the eye.

Jammer indicates that Ernst Mach demythologized the absolute time of Newtonian physics. The receiver (observer) is now subject of Einstein's Special Relativity (SR) and not Galilean relativity. This definition is naturally extrapolated to events in gravitationally-curved spacetimes, and to accelerated observers, through use of a radar-time/distance definition that (unlike the tangent free-float-frame definition for accelerated frames) assigns a unique time and position to any event.[18]. Golovkin BG (2022) Proof of Einsteins postulates. f =2, 2 the speed of light is maximum: v= The speed of light in a vacuum is the same in all coordinate systems moving rectilinearly and uniformly relative to each other. Anything of interest? The RM Santilli Foundation Announces. Obviously, such a negligible mass density of photonics at the modern level of science and technology practically does not allow detection of the influence on the motion of bodies and the processes occurring in the Universe. =70.940.11//M v+u 1980 1981. v the point is John that the 1st postulate says that, @robertbristow-johnson: No, your claim in the comment above is false because you misquote the first postulate. 1. Guts AK. v Ugarov VA. Special theory of relativity. Then the Lorentz transformation expresses how the coordinates are related: The equation t = constant defines a "line of simultaneity" in the (x, t) coordinate system for the second (moving) observer, just as the equation t = constant defines the "line of simultaneity" for the first (stationary) observer in the (x, t) coordinate system. C (6) U 1 For a given observer, the t-axis is defined to be a point traced out in time by the origin of the spatial coordinate x, and is drawn vertically. 2 3 When you are flying in a commercial jet, it may appear to you that the airplane is stationary and the Earth is moving beneath you. 2 You are using a browser version with limited support for CSS. Isn't the "constant speed of light" postulate valid also for sound waves? Paradoxes of the theory of relativity. Explain. , the frequency of the generated sub quanta is extremely high, then over time the photons form sub quanta of the average frequency, and in the limit of their aging ( Table 1 shows the values of the speed of light, depending on its frequency, calculated by the formula (28). = 1, will be practically the same What do I need to build special relativity? The first postulate of special relativity is the idea that the laws of physics are the same and can be stated in their simplest form in all inertial frames of reference. Second postulate (invariance of c) C As can be seen from the above, the answer to the question about the truth of the formula for the addition of velocities (21) for light is explained by the fact that during the transition to the IRS-2, moving relative to the IRS-1, the energy of the relative motion of the IRS does not transform only into a change in the speed of light, but is redistributed between a change in frequency and a change in the speed of light, and change in accordance with formulas (21) and (48). +vu Let us consider how the frequency of light changes when it passes to another IRS. inertial system exists. Also, I can see that special relativity follows directly from the relaxation of the second Galilean postulate and the acceptance of Maxwell's laws, but what arises when you also relax the third Galilean postulate (homogeneity of space & time)? 2 ,(16) It would have electric and magnetic fields that varied in strength at various distances from the observer but were constant in time. 10 const 3 DOI: 2022 Golovkin BG. The speed v only generates a frequency Doppler shift of the received frequency of the EM waves but does not affect the propagation speed of the received waves which is always fixed at speed c in a vacuum. (48) The purpose of this work is to find the value of the fundamental constant C, to find the dependence of the speed of light on frequency, the formula for the change in the frequency of light in the transition to another Inertial Reference System (IRF) and to prove, within the accuracy of modern research methods, the truth of the SRT postulates, called Einsteins postulates.

Explain what an inertial frame of reference is. An exclusive feature of photonics, as the limit of involution of photons, is that it is in Absolute rest in absolutely all frames of reference! AS is well known, Einstein's special theory of relativity rests on two postulates: (1) the postulate of relativity; (2) the postulate of constant light velocity, which says 1 "that .

Bronstein MP. = The Lorentz transformations used in STR were originally derived based on the postulate of the nonrelativistic law of addition of velocities without using the postulate of the maximum speed of light [4,5]. Special relativity resembles trigonometry in that both are reliable because they are based on postulates that flow one from another in a logical way. in the range of -rays were formed.

The basic provision of the article is the existence of photonics, the reality of which is hypothetical. s v According to the experimental data, visible light with a frequency of 1015 s has a speed [22]: v Substituting (51) in (54), we obtain a formula for the mass of a moving body, which coincides with a similar STR formula: m in a vacuum, but they do not specify the frame of reference in which light has this speed. R E u Based mostly on his analysis that the laws of electricity and magnetism would not allow another speed for light, and only slightly aware of the Michelson-Morley experiment, Einstein detailed his second postulate of special relativity. . 1 In papers [12,13], theoretical analysis and classification of hypotheses about the redshift in the spectra of galaxies, as the main reason for the aging of photons, were carried out. Relaxation of this postulate means that almost anything could happen: in particular, nonlinear transformation laws. Deceptively simple and counterintuitive, this and the first postulate leave all else open for change. PTZ: We're glad you're here. u .

A Possible Experimental Test of Einstein's Second Postulate. @RealPattern "SR is not constistent with Galilean relativity." Modern relativity is based on Einsteins two postulates. Santilli RM. 2 Due to the "principle of relative motion", moving observers within the aether also assume that they are at rest and that the speed of light is constant in all directions (only to first order in v/c). This conclusion implies that light in a vacuum must always travel at speed relative to any observer. =h In Minkowski's view, the nave notion of velocity is replaced with rapidity, and the ordinary sense of simultaneity becomes dependent on hyperbolic orthogonality of spatial directions to the worldline associated to the rapidity. The general approach to the problem is to obtain the corresponding functional equation, the solution of which leads to the formula for the addition of parallel velocities [9]. ) The second postulate upon which Einstein based his theory of special relativity deals with the speed of light. 0 The first is that the laws of physics must be the same in any inertial frame of reference (The inertial frame of reference applies to observers that are moving at constant speed or are at rest, i.e., it is not accelerating). Einstein's two postulates of special relativity reads, according to Wikipedia: 1. , Electromagnetic phenomena in a system moving with any velocity smaller than that of light. w Among the changes are the loss of agreement on the elapsed time for an event, the variation of distance with speed, and the realization that matter and energy can be converted into one another. A simple explicit example is a collision of two objects. It should be noted, however, that the experimental Calculating the sign of an indefinite constant is equivalent to the assumption of the presence of a maximum speed, that is, in essence, to the second postulate. does not depend either on the frequency of the primary radiation or on the speed of its source, then such sub quanta, naturally, should be considered limiting particles - photonics. v How to play the "Ped" symbol when there's no corresponding release symbol, Brute force open problems in graph theory. This is no coincidence; what Maxwell had discovered is that light is an electromagnetic wave. )(14) Photonics, i.e., has zero speed and nonzero frequency (34).
