  It has been critically argued by V. A. Leus (Sobolev Institute of Mathematics, Novosibirsk, Russia) that in my proof that Einstein’s Special Theory of Relativity is logically inconsistent and therefore false, I violated the basic tenets of Special Relativity and foisted an alternative theory upon Einstein’s. A careful study of the critical analysis reveals however a failure to address the key arguments I adduced to prove Special Relativity logically inconsistent, and a concomitant invocation of Einstein’s theory to try to argue that my analysis is incorrect because it does not concur with Einstein. There is therefore no proof advanced of any alleged error in my analysis. In my paper I did not introduce an alternative theory. The aforementioned critical paper affords opportunity in rebuttal to amplify the invalidity of A. Einstein’s tacit assumption, in constructing the Special Theory of Relativity, that systems of clock-synchronised stationary observers consistent with Lorentz Transformation can be mathematically constructed. Since such systems of observers have in fact no mathematical existence the Special Theory of Relativity is logically inconsistent. It is therefore invalid. The consequences for physics, astronomy, and cosmology, are significant.

Introduction</title><p>The recent critical paper [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] by V. A. Leus (Journal of Applied Mathematics and Physics) has not addressed the two key arguments I have adduced in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] to prove logical inconsistency of Special Relativity. Instead, a comparison is made of conclusions I drew from my analysis with conclusions Einstein drew from his theory, concluding that my analysis is wrong because my conclusions do not concur with Einstein’s. But that is the whole point: Einstein’s conclusions are erroneous because his theory is logically inconsistent, despite its historical standing.</p><p>The two key arguments I adduced in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] are:</p><p>1) Einstein defined time by means of his clocks. However clocks do not define time. Clocks no more define time than a pressure gauge defines pressure, than a speedometer defines speed, than a graded spring defines gravity. Measuring instruments are invented to measure something other than themselves. Einstein’s clocks measure only themselves. By defining time by means of his clocks, Einstein detached time from physical reality.</p><p>2) Einstein’s method of clock-synchronisation is certainly inconsistent with the Lorentz Transformation, recently proven by Engelhardt [<xref ref-type="bibr" rid="scirp.85392-ref3">3</xref>] , the proof generalised by Crothers [<xref ref-type="bibr" rid="scirp.85392-ref4">4</xref>] . Why then is Einstein’s method of clock-synchronisation inconsistent with the Lorentz Transformation? The answer to this question is given in my paper [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] : to wit, Einstein tacitly assumed that he can construct systems of clock-synchronised stationary observers consistent with Lorentz Transformation. His systems of observers can contain any number of observers. However, in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] I investigate Einstein’s tacit assumption and prove that it is false by first explicitly constructing a system of stationary observers consistent with Lorentz Transformation, proving that these observers cannot be clock-synchronised. I then explicitly constructed a system of clock-synchronised observers consistent with Lorentz Transformation, proving that these observers cannot all be stationary. Therefore Einstein’s tacit assumption is proven false, rendering his theory logically inconsistent and therefore invalid.</p><p>The paper [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] proceeds without any reference to these issues and essentially compares the consequences I drew from (a) and (b) above with the conclusions Einstein drew from his theory.</p></sec><sec id="s2"><title>2.

This is the essence of his tacit assumption: that he can construct systems of clock-synchronised stationary observers consistent with the Lorentz Transformation. It has been proven in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] that such a construction is impossible. The passage in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] has removed from the passage in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] , Einstein’s requirement of a system of clock-synchronised stationary observers. The Lorentz Transformation of itself is not the basis for Einstein’s time dilation and length contraction; systems of clock-synchronised stationary observers and the Lorentz Transformation are both required.</p><p>An objection to <xref ref-type="fig" rid="fig1">Figure 1</xref> above is raised with the following assertion:</p><p>“The depicted drawing is rather bewildering than helpful.

Moreover, my <xref ref-type="fig" rid="fig1">Figure 1</xref> above is a standard representation drawn from the literature, including that of Einstein himself. Note the reference I supplied in the caption to my <xref ref-type="fig" rid="fig1">Figure 1</xref>. <xref ref-type="fig" rid="fig1">Figure 1</xref> is just a reconstruction of figure 12.18 in the cited reference there, “( [<xref ref-type="bibr" rid="scirp.85392-ref4">4</xref>] , &#167;12.1)”, which is now reference ( [<xref ref-type="bibr" rid="scirp.85392-ref5">5</xref>] &#167;12.1) herein. In their book Einstein and Infeld ( [<xref ref-type="bibr" rid="scirp.85392-ref6">6</xref>] &#167;III) present sections of <xref ref-type="fig" rid="fig1">Figure 1</xref> above, as follows:</p><p>The insinuation that I have drawn an inaccurate figure for relativist representations of Einstein’s clocks is not correct. Moreover, the point is that all these diagrams depicting stationary and moving clocks are meaningless.</p><p>In ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;1) there appears a quote from the caption of <xref ref-type="fig" rid="fig1">Figure 1</xref> in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] , reproduced above as <xref ref-type="fig" rid="fig1">Figure 1</xref>:</p><p>“Only at x = ξ = 0 do the clocks depicted read the same time in both systems, where t = τ = 0 .”</p><p>A vague and protracted objection is raised in relation this condition. However, this condition is clearly evident in Einstein’s <xref ref-type="fig" rid="fig3">Figure 3</xref> below, as well as in <xref ref-type="fig" rid="fig1">Figure 1</xref> above. Since Einstein defined time by means of his clocks and their dial readings, dial readings of certain clocks in the K and k systems can look the same at some stage in the relative motion depicted in the figures. This does not mean that the same time interval has been recorded by these clocks, because the clocks are periodic.</p><p>In ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;1) it is asserted:</p><p>“In the second section of his paper [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] the author considers a range of events occurring at positions x σ i = x i in different moments of time t i , which are specified as follows:</p><p>t σ i = t i = t 1 + ( σ i − 1 ) v x 1 c 2</p><p>where t i is at will.”</p><p>This is not correct. The expressions that actually appear in ( [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] &#167;2) are:</p><p>x σ = σ   x 1 (1)</p><p>t σ = t 1 + ( σ − 1 ) v x 1 c 2 (2)</p><p>where in σ ∈ ℜ , x 1 ≠ 0 . Expressions (1) and (2) convey very different outcomes to those alleged in ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;1). The author of [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] has not addressed the right equations. The author’s variable i does not even have a counterpart in expressions (1) and (2). The equations adduced in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] are quite meaningless.</p><p>In relation to <xref ref-type="fig" rid="fig3">Figure 3</xref> in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] , for what the author calls a “neutral point”, is the statement:</p><p>“The time t = T is elapsed in the K system, so the origin of the k system ξ<sub>o</sub> = 0 is located at the point x = vT. The event (x<sub>n</sub>, t<sub>n</sub>), where x<sub>n</sub> = γvT/(γ + 1), t<sub>n</sub> = T, is subject to the Lorentz Transformation (1):” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;1)</p><p>The term x<sub>n</sub> is the author’s “neutral point”. The term ξ<sub>o</sub> and Equation (1) in ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;1) implicate the expressions I adduced in ( [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] &#167;2) for systems of stationary observers consistent with the Lorentz Transformation, namely:</p><p>τ = β ( t σ − v x σ / c 2 ) ,       x σ = σ x 1 , ξ σ = β ( x σ − v t σ ) = β [ ( σ β 2 + v 2 c 2 ) x 1 − v t 1 ] , t σ = t 1 + ( σ − 1 ) v x 1 c 2 ,       η = y ,     ς = z , β = 1 / 1 − v 2 / c 2 ,       σ ∈ ℜ . (3)</p><p>However, “The time t = T is elapsed in the K system” is inconsistent with Equation (3) above, because there is no common time t for the stationary observers of Equation (3)―they cannot be clock-synchronised, contrary to Einstein’s tacit assumption. The “time t = T is elapsed in the K system” is in fact just Einstein’s common time by his false tacit assumption. Furthermore, the “neutral point” x<sub>n</sub> is moving:</p><p>“The neutral point is moving along the x-axis in positive direction with speed v n x = v γ / ( λ + 1 ) .” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;1)</p><p>None of the observers x<sub>σ</sub> in Equation (3) are moving―they are all stationary by mathematical construction (none are functions of time). The neutral point’ argument simply invokes Einstein’s Special Theory of Relativity, which is already proven false by Equation (3). There is nothing in the arguments in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] levelled against Equation (3) above that prove them inconsistent with Lorentz Transformation or inconsistent with Lorentz invariance. These crucial issues are not even addressed.</p></sec><sec id="s3"><title>3. Systems of Clock-Synchronised Stationary Observers and Lorentz Transformation</title><p>Paper ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;2) quotes from [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] :</p><p>“Either way, Einstein’s system of clock-synchronised stationary observers is inconsistent with the Lorentz Transformation.” ( [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] &#167;2)</p><p>The following remarks then appear:</p><p>“This conclusion is fatally wrong. The very notions “stationary-moving” are quite relative: from the point of view of any K-observer the K system is stationary and the k system is in motion, but from the point of view of any k-observer the k system is stationary and the K system is the moving one.” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;2)</p><p>This passage clearly attests that neither my arguments nor those of Einstein have been understood by the author. Einstein’s systems K and k of clock-synchronised stationary observers are each clock-synchronised and stationary with respect to themselves. Einstein then sets his system k of clock-synchronised stationary observers into motion with respect to his system K of clock-synchronised stationary observers; his system K he calls “the stationary system”:</p><p>“Now, however, as we know how to judge whether two, or more, clocks show the same time simultaneously and run in the same way, we can very well imagine as many clocks as we like in a given CS. Each of them will help us to determine the time of events happening in its immediate vicinity. The clocks are all at rest relative to the CS.

That one system is then set into constant rectilinear parallel motion with respect to the other system does not alter this. Einstein’s moving system of clock-synchronised stationary observers is k and his stationary system of clock-synchronised stationary observers is K. There is a difference between systems of clock-synchronised stationary observers and the relative motion of such systems, which has not been recognised in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] . Note also that Einstein asserts that time is defined “by means of stationary clocks in the stationary system.” This is fundamentally incorrect―clocks do not define time.</p><p>I repeat, for emphasis, the objection in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] to my statement that Einstein’s system of clock-synchronised stationary observers is inconsistent with the Lorentz Transformation:</p><p>“This conclusion is fatally wrong.” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;2)</p><p>However, my statement is correct. Engelhardt [<xref ref-type="bibr" rid="scirp.85392-ref3">3</xref>] proved that Einstein’s method of clock-synchronisation is inconsistent with the Lorentz Transformation. I generalised his proof [<xref ref-type="bibr" rid="scirp.85392-ref4">4</xref>] from t = 0 to t ≥ 0, Einstein’s entire time domain. Einstein synchronised his clocks for both his “stationary system K” and his “moving system k”:</p><p>“We have so far defined only an ‘A time’ and a ‘B time’.

However, according to Einstein’s clock-synchronisation method this is impossible because all clocks in his moving system k are synchronised, so that when t &gt; 0, τ &gt; 0 too. Thus, Einstein’s clock-synchronisation method is inconsistent with the Lorentz Transformation [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.85392-ref3">3</xref>] [<xref ref-type="bibr" rid="scirp.85392-ref4">4</xref>] .</p><p>Systems of stationary observers consistent with the Lorentz Transformation cannot be clock-synchronised. In &#167;5 of [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] I mathematically constructed a set of clock-synchronised observers consistent with the Lorentz Transformation, proving thereby that they cannot all be stationary observers. Systems of clock-synchronised stationary observers consistent with the Lorentz Transformation cannot be mathematically constructed. Einstein’s tacit assumption that they can be mathematically constructed is false, yet they are essential to his theory. Therefore his Theory of Relativity is false because it contains an insurmountable logical inconsistency.</p><p>In &#167;3 of [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] I drew conclusions as to lengths of moving rods in relation to systems of stationary observers consistent with the Lorentz Transformation. I proved there that systems of stationary observers consistent with the Lorentz Transformation observe length extension, not length contraction. In [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] an objection is raised to this deduction, with the following:</p><p>“Then in the Section 3 the author addresses the procedure of length measurement. There is a thin rigid rod fixed along the abscissa ξ in his own k system. Let (ξ<sub>1</sub>, τ<sub>1</sub>) and (ξ<sub>2</sub>, τ<sub>2</sub>) be the simultaneous event (τ<sub>1</sub> = τ<sub>2</sub> = τ) of measurement the location of its two ends, so that the rod’s length is L<sub>ξ</sub> = ξ<sub>2</sub> − ξ<sub>1</sub>. The inverse Lorentz transformation gives us these events viewed from the K system:</p><p>( x 1 , t 1 ) = [ λ ( ξ 1 + v τ ) , γ ( τ + v c 2 ξ 1 ) ] ;     ( x 2 , t 2 ) = [ λ ( ξ 2 + v τ ) , λ ( τ + v c 2 ξ 2 ) ] .</p><p>Here the procedure of measurement lost its simultaneity. Thus, the value (x<sub>2</sub> - x<sub>1</sub>) ≠ L<sub>x</sub><sub> </sub>because the rod has shifted during the time interval (t<sub>2</sub> - t<sub>1</sub>) for the distance ΔL = v(t<sub>2</sub> - t<sub>1</sub>). In this case the real rod’s length would be</p><p>L x = ( x 2 − x 1 ) − Δ L = γ ( ξ 2 − ξ 1 ) − γ v 2 c 2 ( ξ 2 − ξ 1 ) = γ ( 1 − v 2 c 2 ) ( ξ 2 − ξ 1 ) = L ξ γ .</p><p>The rod is contracted by the factor γ despite the author’s assertion.” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] , &#167;2)</p><p>This is not correct. The objection is merely Einstein’s theory, as the common time “(τ<sub>1</sub> = τ<sub>2</sub> = τ)” immediately attests. However, relative to the system k the times τ<sub>1</sub> and τ<sub>2</sub> cannot be equal because, by Equation (3), a system of stationary observers consistent with the Lorentz Transformation cannot be clock-synchronised. The inverse Lorentz Transformation adduced in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] for a system of stationary observers is:</p><p>t = β ( τ σ + v ξ σ / c 2 ) ,       ξ σ = σ ξ 1 , x σ = β ( ξ σ + v τ σ ) = β [ ( σ β 2 + v 2 c 2 ) ξ 1 + v τ 1 ] , τ σ = τ 1 − ( σ − 1 ) v ξ 1 c 2 ,       y = η ,       z = ς , β = 1 / 1 − v 2 / c 2 ,       σ ∈ ℜ . (7)</p><p>Neither Equation (3) nor Equation (7) have been directly addressed in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] . Instead, Einstein’s theory has been employed to argue that Equation (3) and Equation (7) must be wrong because they do not concur with Einstein’s theory. But, again, that is the very point: Einstein’s tacit assumption that he can construct systems of clock-synchronised stationary observers consistent with the Lorentz Transformation is false, so his theory is logically inconsistent. His theory is not consistent with the Lorentz Transformation. Equations (3) and (7) are consistent with the Lorentz Transformation. It is therefore to be expected that Equation (3) and Equation (7) do not concur with Einstein’s theory. Consider two identical rigid rods; to each one attached a coordinate system. When there is no relative motion the length of each rigid rod is l<sub>0</sub>, as shown in <xref ref-type="fig" rid="fig4">Figure 4</xref>.</p><p>Now, following Einstein, impart constant motion at speed v &gt; 0 to the system k as in <xref ref-type="fig" rid="fig5">Figure 5</xref>. The moving rod attached to the “moving” system k, as perceived by the stationary observers in the “stationary” system K, has a length Δx and the rod in K has the length l<sub>0</sub> according to observers in K.</p><p>By Equation (3) above,</p><p>Δ x = β l 0 = l 0 1 − v 2 c 2 .

Einstein however maintained that the moving rod is shorter than the stationary rod, owing to his false assumption.</p><p>In ( [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] &#167;4) I showed that although no observer in the stationary system K of stationary observers is clock-synchronised, every observer x<sub>σ</sub> of the stationary system K observes the same time interval in K and the same time-dilated interval as Einstein in the moving system of stationary observers k, but they do so at the expense of length contraction and of clock-synchronised stationary observers, which is irreconcilable with Einstein’s theory. The entire objection to this is simply:</p><p>“In Section 4 the author manipulates with a time interval.” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;2)</p><p>A derivation of Einstein’s time-dilation is then presented in [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] to obtain the very same relation obtained in [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] .</p></sec><sec id="s4"><title>4.

The author neglects basic tenets of the SRT, foists his own and confuses this makeshift ‘theory’ with Einstein’s creature.” ( [<xref ref-type="bibr" rid="scirp.85392-ref1">1</xref>] &#167;3)</p><p>That [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] refutes Special Relativity is no basis for rejection of the refutation. The allegation that I neglect the “basic tenets of the SRT” is simply not true, for it is the basic tenets of SRT that I prove to be false, owing to inherent logical inconsistency.

The reason why is somewhat subtle: Einstein’s tacit assumption that he can construct systems of clock-synchronised stationary observers consistent with the Lorentz Transformation is false [<xref ref-type="bibr" rid="scirp.85392-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.85392-ref8">8</xref>] .</p><p>The Special Theory of Relativity is logically inconsistent. Therefore it is false. The Lorentz Transformation is meaningless.</p><p>The consequences for physics, astronomy, and cosmology, are profound. All aspects of theoretical physics where the Theory of Relativity has been employed must be re-examined because they cannot hold good.
