Résumé :

RESUMO Tradicionalmente, ser realista sobre algo significa crer na existência independente desse algo. Em termos ontológicos, isto é, acerca do que há, o realismo científico pode ser entendido como envolvendo a adoção de uma ontologia que seja cientificamente informada. Mas, segundo alguns filósofos, a atitude realista deve ir além da ontologia. A forma como essa exigência tem sido entendida envolve fornecer uma metafísica para as entidades postuladas pela ciência. Discutimos como duas abordagens em voga encaram o desafio de fornecer uma metafísica para a ciência: uma forma de naturalismo e a abordagem Viking/Toolbox. Por fim, apresentamos uma terceira via, que adota o melhor das duas abordagens: o método metapopperiano, que foca em descartarmos quais as alternativas erradas, ou melhor dizendo, os perfis metafísicos incompatíveis com certas teorias. Apresentamos o método metapopperiano, um método de metametafísica capaz de avaliar objetivamente quais os perfis metafísicos que são incompatíveis com certas teorias científicas. Para isso, usaremos como estudo de caso a mecânica quântica, mostrando resultados obtidos previamente. Com esse método, podemos ver como a ciência pode ser usada para evitar o erro em questões metafísicas. Essa seria, na nossa opinião, uma forma de desenvolver uma relação produtiva entre ciência e metafísica.

Résumé :

By applying a method of virtual quanta we derive formulae for relativistic non-thermal bremsstrahlung radiation from relativistic electrons as well as from protons and heavier particles with power-law momentum distribution N(p)dp = k p-qdp. We show that emission which originates from an electron scattering on an ion, represents the most significant component of relativistic non-thermal bremsstrahlung. Radiation from an ion scattering on electron, known as inverse bremsstrahlung, is shown to be negligible in overall non-thermal bremsstrahlung emission. These results arise from theory refinement, where we introduce the dependence of relativistic kinetic energy of an incident particle, upon the energy of scattered photon. In part, it is also a consequence of a different mass of particles and relativistic effects.

Résumé :

Questa tesi si focalizza sullo studio di due ambiti di ricerca principali: teorie di campo non relativistiche e complessità olografica. Nella prima parte riesaminiamo la classificazione generale dell'anomalia di traccia per teorie di campo 2+1 dimensionali accoppiate a una geometria di Newton-Cartan e revisioniamo anche il metodo dell'heat kernel, che è utilizzato per studiare azioni effettive a un loop e permette quindi di calcolare le anomalie per una data teoria. Applichiamo questa tecnica per estrarre i coefficienti esatti dei termini di curvatura dell'anomalia di traccia sia per uno scalare che per un fermione liberi e non relativistici, trovando una relazione con l'anomalia conforme della controparte relativistica in 3+1 dimensioni che suggerisce l'esistenza di una versione non relativistica del teorema a su cui commentiamo. Proseguiamo l'analisi dello scalare e del fermione libero e non relativistico con il metodo dell'heat kernel accendendo una sorgente per la massa delle particelle: in questa geometria, troviamo che non c'è anomalia gravitazionale, ma l'anomalia di traccia non è invariante di gauge. In seguito consideriamo un modello specifico che realizza un'estensione supersimmetrica N=2 del gruppo di Bargmann in 2+1 dimensioni con superpotenziale non nullo, ottenuto dalla riduzione dimensionale lungo una direzione nulla del modello di Wess-Zumino relativistico. Controlliamo che il superpotenziale è protetto contro le correzioni quantistiche come nella controparte relativistica, così trovando une versione non relativistica del teorema di non rinormalizzazione. Inoltre, abbia una forte evidenza che la teoria è esatta a un loop, a causa della struttura causale del propagatore non relativistico e a causa della conservazione della massa. Nella seconda parte della tesi revisioniamo le congetture olografiche proposte da Susskind per descrivere l'evoluzione temporale del ponte di Einstein-Rosen in teorie gravitazionali: la complessità=volume e la complessità=azione. Queste quantità possono essere usate come un modo per studiare dualità, e noi consideriamo sia il volume che l'azione di buchi neri in spazi AdS_3 warped, che costituiscono delle deformazioni non banali dell'usuale AdS_3, aventi isometrie al bordo non relativistiche. In particolare, calcoliamo analiticamente la dipendenza temporale della complessità trovando una derivata temporale asintotica proporzionale al prodotto della temperatura di Hawking e dell'entropia di Bekenstein-Hawking. In questo contesto, esistono estensioni delle proposte olografiche quando lo stato duale in teoria dei campi è misto, cioé consideriamo soltanto una sottoregione del bordo. Calcoliamo la struttura delle divergenze ultraviolette, il comportamento sub/super-additivo della complessità e la sua dipendenza dalla temperatura per buchi neri warped in 2+1 dimensioni, quando la sottoregione è uno dei bordi disconnessi dello spaziotempo. Infine, calcoliamo analiticamente la complessità=azione per una sottoregione data da un segmento nella geometria del buco nero BTZ, dimostrando che è uguale alla somma di un termine divergente direttamente proporzionale alla lunghezza della sottoregione, più un termine proporzionale all'entropia di entanglement. Mentre questo risultato suggerisce un forte legame tra complessità ed entropia di entanglement, dimostriamo che nel caso di due segmanti disgiunti nella geometria del BTZ ci sono dei termini finiti aggiuntivi: quindi, la precedente elegante struttura rimane vera solo per le parti divergenti.
This thesis focuses on the investigation of two broad research areas: non-relativistic field theories and holographic complexity. In the first part we review the general classification of the trace anomaly for 2+1 dimensional field theories coupled to a Newton-Cartan background and we also review the heat kernel method, which is used to study one-loop effective actions and then allows to compute anomalies for a given theory. We apply this technique to extract the exact coefficients of the curvature terms of the trace anomaly for both a non-relativistic free scalar and a fermion, finding a relation with the conformal anomaly of the 3+1 dimensional relativistic counterpart which suggests the existence of a non-relativistic version of the a-theorem on which we comment. We continue the analysis of non-relativistic free scalar and fermion with the heat kernel method by turning on a source for the particle mass: on this background, we find that there is no gravitational anomaly, but the trace anomaly is not gauge invariant. We then consider a specific model realizing a N=2 supersymmetric extension of the Bargmann group in 2+1 dimensions with non-vanishing superpotential, obtained by null reduction of a relativistic Wess-Zumino model. We check that the superpotential is protected against quantum corrections as in the relativistic parent theory, thus finding a non-relativistic version of the non-renormalization theorem. Moreover, we find strong evidence that the theory is one-loop exact, due to the causal structure of the non-relativistic propagator together with mass conservation. In the second part of the thesis we review the holographic conjectures proposed by Susskind to describe the time-evolution of the Einstein-Rosen bridge in gravitational theories: the complexity=volume and complexity=action. These quantities may be used as a tool to investigate dualities, and we investigate both the volume and the action for black holes living in warped AdS_3 spacetime, which is a non-trivial modification of usual AdS_3 with non-relativistic boundary isometries. In particular, we analytically compute the time dependence of complexity finding an asymptotic growth rate proportional to the product of Hawking temperature and Bekenstein-Hawking entropy. In this context, there exist extensions of the holographic proposals when the dual state from the field theory side is mixed, i.e. we consider only a subregion on the boundary. We study the structure of UV divergences, the sub/super-additivity behaviour of complexity and its temperature dependence for warped black holes in 2+1 dimensions when the subregion is taken to be one of the two disconnected boundaries. Finally, we analytically compute the subregion action complexity for a general segment on the boundary in the BTZ black hole background, finding that it is equal to the sum of a linearly divergent term proportional to the size of the subregion and of a term proportional to the entanglement entropy. While this result suggests a strong relation of complexity with entanglement entropy, we find after investigating the case of two disjoint segments in the BTZ background that there are additional finite contributions: then the previous elegant structure holds only for the divergent parts.

In this work, one searchs to investigate the influence of violating terms of Lorentz and CPT (in "vectorial"and "axial"couplings ) on the equation of Dirac, and its non-relativistic limit. Firstly, its solutions of wave-planes, relation of dispersion and eigenvalues are gotten. After that, the limit of low energies is worked and determined the non-relativistic Hamiltonian. In the case of the vectorial coupling, the breaking terms do not induce any modification on the spectrum of hydrogen (in the presence or absence of external magnetic field), what it is in accordance with the fact of this background only to determine the displacement at the momentum of the system. In the case of the pseudo-vectorial coupling, however, the non-relativistic Hamiltonian possesss a term that modifies the spectrum, inducing an alteration of energy similar to Zeeman effect (in the absence of external magnetic field). Such effect is then used to establish the upper limit on the magnitude of background:bz < 10¡10eV . In the second part of this work, is analyzed the influence of a fixed background, violating of Lorentz, in a non-minimum coupling on the sector of fermions, on the equation of Dirac. The non-relativistic regime is considered and the Hamiltonian accomplished. The effect of this Hamiltonian on the spectrum of hydrogen is determined in calculations of first order (in the absence of external magnetic field), revealing the presence of energy shifting that modifies the fine structure of the spectrum and makes possible the imposition of a upper limit on the breaking product:gvz < 10¡14(eV )¡1. In the presence of external magnetic field, a correction of energy also is gotten, implying in the limit:gvz < 10¡25(eV )¡1. In the case where the non-minimum coupling is of the type torsion, no first order correction is shown in the absence of external field; in the presence of a external field, a second Zeeman effect is observed, implying in:gvz < 10¡25(eV )¡1. Such results show that the effect of Lorentz violating can more significantly be investigated in way to the presence of a external field.
Neste trabalho, busca-se investigar a influência de termos violadores de Lorentz e CPT (em acoplamentos "vetoriais"e "axiais") sobre a equação de Dirac, e seu limite não-relativistico. Primeiramente, são obtidas as suas soluções de onda-plana, relação de dispersão e autovalores. Em seguida, o limite de baixas energias é trabalhado e o Hamiltoniano não-relativistico determinado. No caso do acoplamento vetorial, os ter- mos de violação não induzem qualquer modificação sobre o espectro do hidrogênio (na presença ou ausência de campo magnético externo), o que está de acordo com o fato deste background determinar apenas um deslocamento no momento do sistema. No caso do acoplamento pseudo-vetorial, entretanto, o Hamiltoniano não-relativistico possui um termo que modifica o espectro, induzindo uma alteração de energia similar ao efeito Zee- man (na ausência de campo magnético externo). Tal efeito é então usado para estabelecer um limite superior sobre a magnitude do background: bz < 10¡10eV Na segunda parte deste trabalho, é analisada a influência de um background bz xo, violador de Lorentz, em acoplamento não-minimo sobre o setor de férmions, sobre a equação de Dirac. O regime não-relativistico é considerado e o Hamiltoniano estabelecido. O efeito deste Hamiltoniano sobre o espectro do hidrogênio é determinado em cálculos de primeira ordem (na ausência de campo magnético externo), revelando a presença de desvios de energia que modificam a estrutura fina do espectro e possibilitam a imposição de um limite superior sobre o produto de violação: gvz < 10¡14(eV )¡1. Na presença de campo magnético externo, uma correção de energia é também obtida, implicando no limite:gvz < 10¡25(eV )¡1.No caso em que o acoplamento não-minimo é do tipo torção, nenhuma correção de primeira ordem é exibida na ausência de campo externo; na presença de um campo externo, um segundo efeito Zeeman é observado, implicando emgvz < 10¡25(eV )¡1. Tais resultados mostram que o efeito de violação de Lorentz pode ser mais sensivelmente investigado em meio à presença de um campo externo.

Résumé :

In this thesis we study inflation from a string theory point of view. The first part of the work is dedicated to reviewing how this mechanism can solve the main problems of the Standard Hot Big Bang (HBB) Cosmology and how it can be built in the context of General Relativity. The second part focuses on the application of the principles of string theory to inflation. In this framework an inflationary model can be viewed as an effective field theory in the super-gravity limit. In particular we concentrate on inflationary models in which the effective Lagrangian is obtained from the dimensional reduction of the Dirac-Born-Infeld (DBI) action, which describes the position and orientation of a $D7$-brane. This effective Lagrangian contains a non-trivial kinetic term. We study the effects of this non-trivial kinetic term on the speed of sound $c_s$, on the tensor-to-scalar ratio $r$ and on the spectral index $n_s$ in the case of monomial potentials, generalizing the work done by Ibanez and Pedro. We find that the system never enters the relativistic regime and therefore $c_s\simeq 1$. This justifies the truncation of the DBI action to second order derivatives. In the final chapter we see how the Swampland criteria, when applied to $DBI$ inflation, push the system into the relativistic regime and lead to a strong decrease of $c_s$.

Résumé :

A problem of non-relativistic quantum mechanics solved using regularization and renormalization techniques is presented in this thesis. After a general introduction of these techniques, they are applied to a problem in classical electromagnetism and to the bound state of a single quantum particle subjected to a two-dimensional delta-function potential, that is divergent if computed naively solving directly the Schroedinger equation or using the theory of propagators. The regularization techniques used are the cutoff regularization and the dimensional one and they both leads to the same outcome. An effective field theory approach, in which the potential is regularized through the real space scheme, is also presented. After regularization has been performed, the potential is renormalized re-defining the coupling constant. The running of the renormalized coupling constant is also found, i.e. the renormalization group equation.

Cataloged from PDF version of thesis.

Motivated by the AdS/CFT correspondence for relativistic CFTs, it seems natural to generalize it to non-relativistic CFTs. Such a dual description could provide insight into strong coupling phenomena observed in condensed matter systems. Scale invariance can be realized in non-relativistic theories in many ways. One freedom is the relative scale dimension of time and space, called the dynamical exponent z. In this thesis, we will mainly focus on the case where z = 2, however gravity duals for other values of z have also been found. In the first part of the thesis, we study NRCFTs that are Galilean invariant. Discrete light cone quantization (DLCQ) of V= 4 super Yang-Mills theory is an example of such a system with z = 2 scaling symmetry. A more realistic example of a system with the same set of symmetries is a system of cold fermions at unitarity. These non-relativistic systems respect a symmetry algebra known as the Schrödinger algebra. We propose a gravity dual that realizes the symmetries of the Schrödinger algebra as isometries. An unusual feature of this duality is that the bulk geometry has two extra dimensions than the CFT, instead of the usual one. The additional direction is a compact direction and shift symmetry along this direction corresponds to the particle number transformation. This solution can be embedded into string theory by performing a set of operations (known as the Null-Melvin twist) on AdS5 x S' solution of type IIB supergravity. This method also provides a way of finding a black hole solution which has asymptotic Schrödinger symmetries. The field theory dual of these gravity solutions happens to be a modified version of DLCQ V = 4 super Yang-Mills theory. The thermodynamics of these theories is very different from that of cold atoms. This happens to be a consequence of realizing the entire Schrödinger group as isometries of the spacetime. We give an example of a holographic realization in which the particle number symmetry is realized as a bulk gauge symmetry. In this proposal, the Schrödinger algebra is realized in the bulk without the introduction of an additional compact direction. Using this proposal, we find a confining solution that describes a non-relativistic system at finite density. We use the holographic dictionary to compute the conductivity of this system and it is found to exhibit somewhat unusual behavior. In the second part of the thesis we study gravity duals of Lifshitz theories. These are non-relativistic scale invariant theories that are not boost invariant. These theories do not have a particle number symmetry unlike the boost invariant NRCFTs. We present solutions of 1OD and 111D supergravity theories that are dual to Lifshitz theories. We present a black hole solution that is dual to a strongly interacting Lifshitz theory at finite temperature. We show that the finite temperature correlators in the interacting theories do not exhibit ultra-local behavior which was observed in free Lifshitz theories.

Résumé :

In this thesis, a non-relativistic model of tetraquark in a diquark-antidiquark configuration is investigated. Using a variation of the Cornell potential, the Schrödinger equation is solved numerically, and the four-body problem of the tetraquark is separated into to three two-body problems. The splitting structure is accounted for by a spin-spin interaction term. Several numerical fits are made to different types of meson data to obtain the free parameters of the model, and subsequently, the masses of diquarks and tetraquarks with different constituents are determined. An introduction to the subject of exotic hadrons is presented as well as an overview of the experimental progress concerning tetraquarks. The results obtained in this thesis are then discussed by comparison with other relativistic models and experimental results.
I detta arbete undersöks en icke-relativistisk modell av tetrakvarkar i en dikvark-antidikvark- konfiguration. Genom att använda en variation av Cornellpotentialen löstes Schrödingerekvationen numeriskt och det fyrkroppsproblem som tetrakvarkar utgör delades upp i tre tvåkroppsproblem. Modellen tar även hänsyn till systemets spinn-spinn-koppling. Flera numeriska anpassningar gjordes för olika typer av mesondata för att bestämma de fria parametrarna i modellen. Därefter bestämdes massorna av dikvarkar och tetrakvarkar med olika sammansättningar av deras beståndsdelar. En introduktion till exotiska hadroner presenteras samt en översikt av de experimentella framstegen gällande tetrakvarkar. Resultaten diskuteras och jämförs med andra relativistiska modeller och experimentella resultat.

Résumé :

We studied the physical meaning of tidal force singularities in non-relativistic spacetimes. Typical examples of such spacetimes include Lifshitz spacetimes, Schr\"{o}dinger spacetimes and hyperscaling violation spacetimes. First I will discuss the extension of singularity-free hyperscaling violation geometry. To understand the physical meaning of singularity in the deep non-relativistic IR bulk, I will calculate string scattering amplitudes to find a field theory interpretation of bulk singularity. Since geometric quantities like singularities or horizons are not physical observables in higher spin theory, we will discuss whether it is possible to resolve such singularities in non-relativistic spacetimes from higher spin theory context. We will show singularity resolution cannot be performed in $2+1$ dimensional higher spin theory. Finally, we will give an explicit construction of Schr\"{o}dinger spacetime solutions in $3+1$ dimensional higher spin theory.

Résumé :

This work deals with the new, relativistic direction in quantum econophysics, within the bounds of which a change of the classical paradigms in mathematical modelling of socio-economic system is oﬀered. Classical physics proceeds from the hypothesis that immediate values of all the physical quantities, characterizing system’s state, exist and can be accurately measured in principle. Non-relativistic quantum mechanics does not reject the existence of the immediate values of the classical physical quantities, nevertheless not each of them can be simultaneously measured (the uncertainty principle). Relativistic quantum mechanics rejects the existence of the immediate values of any physical quantity in principle, and consequently the notion of the system state, including the notion of the wave function, which becomes rigorously nondeﬁnable. The task of this work consists in econophysical analysis of the conceptual fundamentals and mathematical apparatus of the classical physics, relativity theory, non-relativistic and relativistic quantum mechanics, subject to the historical, psychological and philosophical aspects and modern state of the socio-economic modeling problem. We have shown that actually and, virtually, a long time ago, new paradigms of modeling were accepted in the quantum theory, within the bounds of which the notion of the physical quantity operator becomes the primary fundamental conception(operator is a mathematical image of the procedure, the action), description of the system dynamics becomes discrete and approximate in its essence, prediction of the future, even in the rough, is actually impossible when setting aside the aftereﬀect i.e. the memory. In consideration of the analysis conducted in the work we suggest new paradigms of the economical-mathematical modeling.

Résumé :

“Doppler boosting” is a well-known relativistic effect that alters the apparent luminosity of approaching radiation sources. “Doppler de-boosting” is the name of relativistic effect observed for receding light sources (e.g. relativistic jets of active galactic nuclei and gamma-ray bursts). “Doppler boosting” changes the apparent luminosity of approaching light sources to appear brighter, while “Doppler de-boosting” causes the apparent luminosity of receding light sources to appear fainter. While “Doppler de-boosting” has been successfully accounted for and observed in relativistic jets of AGN, it was ignored in the establishment of Standard candles for cosmological distances. A Standard candle adjustment of an Z>0.1 is necessary for “Doppler de-boosting”, otherwise we would incorrectly assume that Standard Candles appear dimmer not because of “Doppler de-boosting” but because of the excessive distance, which would affect the entire Standard Candles ladder at cosmological distances. The ratio between apparent (L) and intrinsic (Lo) luminosities as a function of the redshift Z and spectral index α is given by the formula ℳ(Z) = L/Lo=(Z+1)α -3 and for Type Ia supernova appears as ℳ(Z) = L/Lo=(Z+1)-2. “Doppler de-boosting” may also explain the anomalously low luminosity of objects with a high Z without the introduction of an accelerated expansion of the Universe and Dark Energy.

Résumé :

"Doppler boosting / de-boosting" is a well-known relativistic effect that alters the apparent luminosity of approaching/receding radiation sources. "Doppler boosting" alters the apparent luminosity of approaching light sources to appear brighter, while "Doppler de-boosting" alters the apparent luminosity of receding light sources to appear fainter. While "Doppler boosting / de-boosting" has been successfully accounted for and observed in relativistic jets of AGN, double white dwarfs, in search of exoplanets and stars in binary systems it was ignored in the establishment of Standard Candles for cosmological distances. A Standard Candle adjustment appears necessary for "Doppler de-boosting" for high Z, otherwise we would incorrectly assume that Standard Candles appear dimmer, not because of "Doppler de-boosting" but because of the excessive distance, which would affect the entire Standard Candles ladder at cosmological distances. The ratio between apparent (L) and intrinsic (Lo) luminosities as a function of redshift Z and spectral index α is given by the formula ℳ(Z) = L/Lo=(Z+1)^(α-3) and for Type Ia supernova as ℳ(Z) = L/Lo=(Z+1)^(-2). These formulas are obtained within the framework of Special Relativity and may require adjustments within the General Relativity framework.

Texte intégral

Résumé :

The hypothetical “Dimming effect” describes the change of the number of photons arriving from a receding light source per unit of time. In non-relativistic systems,the "Dimming effect" occurs due to the fact that as light sources move away, the distance between the emitter and the receiver constantly increases, and the photons always take longer to reach the receiver. This reduces the number of photons received per time unit compared to the number of emitted photons per time unit. Negligible for speeds incomparable with the speed of light c, the "Dimming effect" can be very significant for speeds above 0.1c. “Dimming effect” can possibly be tested in a physics labor-atory using a moving light source (or mirror) and photon counters located in the travel direction and in opposite direction. It can possibly also be tested utilizing the orbital movement of the Earth around the Sun. If confirmed, “Dimming effect” would allow astronomers to adjust values of the "Standard Candles", which are critical in cosmological models. Absence of “Dimming effect” will mean that the number of photons arriving per time unit does not depend on the relative speed of light source and observer,which is not so apparent

Texte intégral

Résumé :

“De-boosting” is a well-known relativistic effect that alters the apparent luminosity of radiation sources with the non-zero redshift parameter z. It exists in both Special Relativity and General Relativity frameworks and is proportional to (z+1)^(-2). While the “boosting” (for blueshift) and “de-boosting” (for redshift) of light sources has been successfully accounted for and observed in research of various astronomical objects, it was ignored in the establishment of Standard candles for cosmological distances. A Standard candle adjustment appears necessary for “de-boosting” for high z, otherwise we would incorrectly assume that Standard candles appear dimmer, not because of “de-boosting” but because of the excessive distance, which would affect the entire Standard candles ladder at cosmological distances. The “de-boosting” correction of the apparent luminosities of SNIa places the effective rest-frame magnitudes below the curve corresponding to the cosmological model with the parameters Λ=0 and (ΩM, ΩΛ) = (2, 0) on the Hubble diagram. This way, the “de-boosting” correction of the apparent luminosities of SNIa may further adjust and clarify cosmological models.

Résumé :

The hypothetical “Dimming Effect” describes the change of the number of photons arriving from a moving light source per unit of time. In non-relativistic systems, the “Dimming effect” may occur due to the growing distance of light sources moving away from the receiver. This means that due to the growing distance, the photons continuously require more time to reach the receiver, which reduces the number of received photons per time unit compared to the number of emitted photons. Understandably, the proposed “Dimming effect” must be tested (confirmed or rejected) through observations. a. This article provides the formula for the calculation of “Dimming effect” values using the redshift parameter Z widely used in astronomy. b. The “Dimming effect” can possibly be detected utilizing the orbital movement of the Earth around the Sun. In accordance to the “Dimming effect”, observers on Earth will view 1.0001 more photons per time unit emitted by stars located near the ecliptic plane in the direction of the Earth orbiting the Sun. And, in contrast, observers will view only 0.9999 photons per time unit emitted by stars located near the ecliptic plane in the direction opposite to the Earth orbiting the Sun. Calculating precise measurements of the same stars within a 6-month period can possibly detect this difference. These changes in brightness are not only for specific stars, as the change in brightness takes place for all stars near the ecliptic in the direction of the Earth’s orbit around the Sun and in the opposite direction. c. The “Dimming effect” can possibly be detected in a physics laboratory using a moving light source (or mirror) and photon counters located in the direction of travel and in the opposite direction. d. In theory, Dilation of time can also be used for testing the existence of the “Dimming effect.” However, in experiments on Earth this effect appears in only the 14th digit after the decimal point and testing does not appear to be feasible. e. Why is it important to test the “Dimming effect?” If confirmed, it would allow astronomers to adjust values of "Standard Candles" used in astronomy. Since “Standard Candles” are critical in various cosmological models, the “Dimming effect” can correct models and/or reveal and support new models. If it is proved that the “Dimming effect” does not exist, it will mean that the number of photons arriving per unit of time does not depend on the speed of the light source and observer, which is not so apparent.
